 <p>喷当代中国大陆的“考场作文”制度</p>
 <p>浅显的中国历史我们都学过。教科书上说什么“八股取士”是一种怎么怎么样的做法（诸如钳制思想，阻碍人类发展之类，我早就还给我可亲可敬的历史老师了）。那么，现在我的观点是：现代中国大陆的考场作文制度毒害人的程度，比八股取士什么玩意儿的深十倍乃至百倍！</p>
-<p>写得一手好文章，原是一件好事，在许多方面都有用的。但是，对于像我这样的，编一篇考场作文比便秘拉不出 (bi——) 还困难的人来说，写那种东西基本就是对我们的残害了。拿到作文题目，搜肠刮肚完还不知道如何去作的时候，已经十分惆怅了。然而，还有人追在你屁股后面，要你拉出来的 (bi——)！（这个比喻一点儿也不失当，因为这样憋出来的作文往往跟 (bi——) 一样臭）。便秘了还要逼人家拉出来，这是一种多么不人道的行为！肠在这种摧残之下，尚有发生直肠癌的可能性，而我们的榆木脑袋……</p>
-<p>好好好！你说写这种东西对我们有好处，那我们来看看到底有什么好处！我们来随便看几篇“考场佳作”的题目：什么“熄灭蜡烛，莫惊扰美”，什么“心有猛虎，细嗅蔷薇”，什么“纸梯”，超浓的“文学气息”，一看就不是实用的文章。（我不是故意挑的——因为那本书上可以找到的题目全都这样…）那么，这种题目，善于写作的人写出来，叫“美文”；我这号人写出来，必然就是 (bi——) 了。将来，善于写作的人从办公室里出来，可以写上两篇作为娱乐，陶冶身心。而我扫完大街回窝之后还要玩上一次便秘？！别开玩笑了！我不是 masochist （受虐狂）！再者，我还要为我仅剩的一点大脑负责呢！</p>
-<p>那么又有人说话了（我妈就是其中的一位）：“这对你将来写论文还有用处哩！”我对此实在无话可说。那么假设有万分之一的可能性，我高中毕业没去扫大街，还考上了名校——石油大学，我该写论文了。然后我的论文落笔一个“人生如梦，年华似雪”，抬笔又是“自然而缓慢的优雅的成长”…… (bi————————)! Pardon my French （对不起我爆粗了）！便秘的事就不用提了，因为光想象一下论文里要出现这种东西就得让我恶心上一个小时！</p>

 <p>如果你同意以上我的观点，你现在应该同意考场作文对我这样的废物一点儿好处也没有了。（如果你认为我还有救，那一定是因为你没救了。）那么为什么我要说这东西对普天下都有害呢？下面我就要喷喷这制度了。</p>

 <p>首先，最为可恨的一点，是每道作文题目必有的“自定立意”。第一次我看到这四个字，欣喜若狂，以为就可以把自己扫遍全天下大街大志表达出来了。殊不知有人已经在背后把立意分了三六九等，而我这个恰好处在下下等，发下来一看，20分！</p>

-<p>与此相比，英语作文就开明得多（或许是考虑到我们英语水平太低的缘故）。要写“十年后的我”，我就写我十年后扫大街，居无定所，饥一顿饱一顿，这还得了 80% 的分。这种东西上了语文考场作文，估计直接就零分啦！可今年某省的高考作文还要人大谈“大学的门与路”。故意歧视我们这些没学上的学渣是不是！这种出题人，就该让他们在全省乃至全国学渣的口水中淹死！</p>

 <p>嘛，我差不多喷完了。在此我特地公布一下前段时间我做的一个调查的结果。问题是：“你认为现在所写的语文考场作文，对你的将来……”调查的对象是本校本年级学生45名，其中不乏作文常被当作范文的。没有人选择“非常有用”或“不知道”，而选择“有一定用处”和“完全没用”的人数比大约为1:2——和我的预测基本相同。从此我们至少可以看出一点问题。但我们伟大的出题人们还在命这种题：“贴近社会生活，有人文气息，让考生有话说”。这种题，让我这种学渣有什么话说！</p>

 <p>文中提到的英语作文一事，是确有其事的。某种程度上是为写本文故意做的一次试验。</p>
 <p>文中提到的调查是存在的。不过调查对象全都是理科生（文科生当时和我们不在同一座教学楼里），结果自然是自动偏向对我的结论有利的。</p>
 <p>文中充满着我高中时代典型的自嘲。如果你看了本文的纸质版，你会感到（当时的）我对这种考场作文的痛恨从纸上渗出来（转写到屏幕上之后这种效果虽然有所减弱，但从标点符号和语言的使用上还是能看出一些来的——虽然什么东西从屏幕上渗出来听起来有些奇怪）。这种痛恨是如此的强烈，以至于我高中几乎没有写过一篇严肃的考场作文。大部分写出来的，都是用来气老师的。如此一来即使我不写作文作业，或者模拟考试答题纸作文面直接空白，老师也不会找我的麻烦——既免去我写作文的痛苦，又免去老师读我写的东西的折磨，真是两全其美。</p>
-<p>要是说高中从不练习写作如今有没有什么后悔之处，那么我 GRE 的作文不过关可以说勉强算是一点。但 GRE 作文不像高考英语，CET或者托福英语。后者考的是语言使用能力，而 GRE 考查的是思辨能力。所以从这个角度讲，就算我的高中语文考场作文次次满分， GRE 作文估计也达不到一半人的水平，那么也没有什么可后悔的地方了。</p>
-<p>举个随便编的例子来说， GRE 的作文题目可能是这样的：当地政府人员宣布了一项计划，计划在本地的河上建造一座水库。并且声称由于甲、乙、丙原因，水库建造后当地的居民人均寿命可以翻 10 倍。要求答题者分析政府的主张是否存在漏洞（当然是有的）。</p>

 <p>而中国的高考作文考的是什么？似乎首要是学生的政治“觉悟”，其次是使用华丽词句的能力。前者加上近年来越来越红的作文题目（见我2018年与山东考生一起写的高考作文（<a href="/blog/post/2018-06-07.html">链接</a>）），让人不得不怀疑考场作文成了灌输特定价值观的工具。至于使用华丽词句的能力，我想也许不是所有人都需要的吧。朴实无华的文字，只要传递了作者想要表达的信息，也就达到了目的；华丽的辞藻，反倒可能提高阅读的门槛，即便要表达的思想是如何卓越，也许也无法为大众所接受。</p>
 <p>思辨（或者称为批判性思维）能力，至少让人在与人争论时能够发现对方是否存在逻辑上的漏洞和谬误，并且可以帮助自己避免类似的错误。而对固定价值观的灌输，则恰恰相反：让人不问一切地接受得到的信息，成为容易上当受骗的天真幼稚之人。这两种教育方式，高下立判。</p>
-<p>如果你认为我在对我的“美国主子”表忠心，那你就错了。请不要忘记 GRE 是研究生水平的考试。在研究生考试考如此水平的思辨，还是太晚了。不然的话美国也不会有如此大数量的疫苗反对者 (anti-vaxxer) 或者地平说支持者 (flat earther)。我认为基本的思辨能力应该放在基础教育阶段。那样至少可以减少一些所谓保健品的诈骗案的数量。</p>

 <p>阁下看到这里，心里的感觉若是“哇这人他写了些什么我怎么什么都看不懂”，那确实怪不得阁下。表达能力低下大概是我另一个略微后悔高中从不写作文的地方。这种表达能力的低下，是跨越语言的——可能有人读到我的英文博客文章，感觉还相对通顺，但并不知道背后是经过我自己好多遍审阅改写才成为最终版本的。很多时候脑中根本无法组织用来描述我的想法的语言，这时才后悔年轻的时候没有练习写作；但一想到当时练习写作就意味要着写违心的或者毫无营养文字，这种后悔就直接烟消云散了。</p>

+<p>SBS 2.0 is archived and retired immediately. Old URLs will not be

 <p>Full changelog below:</p>
 <ul>
 <li>+ Static page generator using node.js.</li>
 <li>+ Content encryption with AES instead of simple XOR.</li>
-<li>+ Decryptor now remembers every correct passphrases in local storage and try to decrypt once the page has been loaded.</li>
-<li>+ Optional custom preprocessor pass for markdown/reStructuredText support.</li>
-<li>- Vim-like command buffer, animations and key bindings removed on the posts listing page.</li>

+support.</li>
+<li>- Vim-like command buffer, animations and key bindings removed on
+the posts listing page.</li>
 </ul>

 <h2 id="tocanch0" class="tvis"><em>STUDIO Canvas</em> acquired</h2>
-<p>Ever since I learned that ZUN uses a SD-90 as one of his major synthesizers <a href="https://www12.atwiki.jp/touhousoundfont/pages/22.html">here</a>, I’ve always been dreaming to get my hands on one of those. But these things are not particularly easy to find in China. There are plenty of deals on ebay though. However, after a failed purchase attempt made in 2016 which also led to the ridiculous suspension of my ebay account, I left the idea alone for multiple years. Things changed earlier this month, when <a href="https://owner203.com">owner203</a> helped me acquire my very own SD-80 and kindly delivered it from Japan.</p>
-<p>I did not go for a SD-90 since they are all ridiculously priced in 2019. The deal I tried to make back in 2016 would cost me around $300 (shipping included). Now they are all way beyond $400. This forced me to resort to lower-end models, namely the SD-80 and SD-20. There’s also the SD-50 which I almost bought back in 2014, before I found out it is essentially a stripped-down version of Roland SonicCell without the SRX expandability. Therefore although the SD-50 retains the compatibility with the synth engine found in SD-90 (both are from models supporting SRX, namely the XV-5080 and SonicCell), it comes with a complete new set of waveforms and patches which makes it sounds totally different. So the SD-50 is definitely a no go.</p>
-<p>The only choices left are SD-80 and SD-20. SD-20 can be found very cheap online (from $59). However SD-20 does have half of the polyphony and most editability of other STUDIO Canvas’ axed. Also gone are 3 entire sound banks (and presumably some waveforms). On the other hand, SD-80 costs a lot more (starting from ~$200), but is capable of generating everything the SD-90 can (the only missing part in SD-80 compared to SD-90 is the audio interface). After deciding no more compromise should be made, I went straight for the SD-80.</p>
-<p>The module arrived two weeks after the order was placed. It certainly wasn’t the happiest SD-80 in the world: the chassis bears quite a lot of scratches all around. The value knob takes a lot of force to turn and has a good amount of friction on it, to which I found a quick solution by simply pushing the knob downwards a little bit while turning it. Aside from the looks, the module itself is in perfect working order. It came with a power cord and its rack mount ears, but without any of its original paperwork or the CD-ROM. As most of the documentation and drivers can be found online, the only things I’ve lost are the demo midi files, which is still a shame.</p>

 <h2 id="tocanch1" class="tvis">The configuration</h2>
 <h3 id="tocanch2" class="tvis">Connection to the computer</h3>
-<p>Without the audio interface portion, it’s impossible to use the SD-80 with only a USB connection: you need something for it to connect to in order to make a recording.</p>
-<p>To begin with, I wanted to get something that accepts S/PDIF input for the audio interface. But those kind of things are scarce today. The closet model I could find in Chinese market was from an unknown vendor and comes with a very sketchy chip, whose official driver only supports up to Windows 7 32-bit. As a crappy digital interface may sound worse than a more decent analog one, I went for one of the cheapest audio interfaces available: a Focusrite Scarlett Solo (which is more than 5 times the price of the weird digital interface and probably still better than the one comes with SD-90 as it supports up to 192 KHz sampling rate).</p>
-<p>For a audio equipment novice, connecting things up wasn’t that straightforward: I tried connecting the phone output on the SD-80 to the line in of the audio interface and it kind of works. There is just one <em>tiny</em> problem: the left and right channels got mixed up into one, and is only on the right channel in a stereo recording. At first I thought it was my cable. But after a couple minutes of researching, I found out that every input on an audio interface is actually mono. <strong>WHY</strong>? Guess I’ll never know.</p>
-<p>So I got another TRS to XLR connector. After connecting the left channel of output 1 on the SD-80 to the microphone input on the audio interface and the right channel to line level input, it produces stereo recordings as expected. The resulting audio is very unbalanced though, due to the microphone input being much more sensitive than the line level input. In order to balance them I played a sine wave on the SD-80 and adjust the input level of each channel so that while turning down the volume knob on the SD-80, the level indicators on all channels stop blinking at the same time.</p>
-<p>The ‘direct monitor’ switch on Scarlett Solo enables live monitoring of the input without operating system intervention and therefore, without latency. However the direct monitor feature on Scarlett Solo is limited to mono only, so in order to get stereo monitoring, a round-trip through the computer is required.</p>

 <p>The editor for SD-80 works perfectly using wine.</p>
 <h3 id="tocanch4" class="tvis">Setting things up in Windows</h3>
-<p>Setting things up in Windows is somehow more tedious than it should be. Roland didn’t bother releasing a driver for Windows 10, but a web search indicates the driver for Windows 8/8.1 works on Windows 10 with a minor tweak.

 <h3 id="tocanch7" class="tvis">UPDATE: 2019-10-12</h3>
-<p>Now that I’ve been using my SD-80 for some time, I could say more about the sounds built into it.</p>
-<p>Piano sounds in the SD-80 are not super compelling, mainly because it’s too bright and thin. Sure it has improved a lot since the early days, but it’s still nowhere near the real thing.</p>
-<p>Guitars and basses are in a similar situation. Most of these are also nowhere near realistic. However there <em>is</em> something worth of noting in this category, which is distortion guitar. Dist guitar presets with MFX pre-applied are much more better sounding than the old plain sample-based sounds.</p>
-<p>Orchestral sounds are expressive, sometimes overly expressive. There are not much variations either: no spiccato or solo pizzicato sounds. With a bit of tweaking though, symphony tracks do sound decent on the SD-80.</p>
-<p>Lead sounds and pads are superb, especially those from the special sets. With the editor a lot more nice sounds could be created. A lot of presets with step modulation typical of that days could be found both built-in and on the Internet (as midi system exclusive messages).</p>
-<p>Drums are half decent. Somehow I don’t really like Roland’s choice of their acoustic drum sets. I would always turn to other virtual drums for acoustic drums. Electric drum sounds are pretty good, but there are simply not enough electric drum sounds inside the SD-80.</p>
-<p>Also I don’t really like how Roland arranges the sounds into 4 GM2 sound sets. This severely limits the number of different kind of instruments. For example, rather than a lot of different vocal sounds that can be found in the SC-8850, in the SD-80 we only have Voice Oohs, Voices Oohs 2, St.&nbsp;Vox Oohs and Enh.Vox Oohs.</p>
-<p>The GS and XG lite modes don’t sound very good, which contain sounds that are more like stripped down version of its native presets than a genuine GS or XG lite synthesizer. The GS sounds are almost pathetic: it only come with the same instrument map as the SC-55, and sounds really cheap. Compatibility wise, however, the SD-80 does a nice job. It does seem to support all NRPNs and control messages of these standards (even though it sometimes screw up parameter scaling). But due to the fact that there aren’t really a lot of usable sounds in these modes, I don’t find these modes particularly useful.</p>
-<p>The SD-80 has 32MB of sample content <a id="n6" href="#note6" class="note">[6]</a>, which is on par with both SC-8850 and XV-5080. This is quite surprising because some of the sounds in XV-5080 are so much more realistic than those in SD-80 or SC-8850. The XV-5080 managed to squeeze 1083 samples into the 32MB wave ROM while the SD-80 only comes with 589 samples, which are often of lower quality. I don’t quite get why Roland did this.</p>

 <h2 id="tocanch8" class="tvis">Working with the SD-80</h2>
 <h3 id="tocanch9" class="tvis">Fighting against latency</h3>
-<p>Even though Scarlett Solo can achieve a very low latency, there’s no way I can squeeze out enough processing power out of my ULV dual core i7 to handle it. Therefore I was forced to live with ~11 ms latency, which is not <em>that</em> high, but still a quite significant amount to deal with.</p>
-<p>Cakewalk’s glitchy latency compensation makes things even worse: it works in some projects but completely out of order for the others. In order to listen to a full mix, I have to make a short recording, which is really annoying. As this is much more expensive time-wise, I started using more guesswork before trying a full mix and it’s probably not good.</p>

-<p>Recording is simple and works as expected. However I seem to suffer from quite a high SNR value, which hovers around ~90 dB. Perhaps it’s my crappy cables making me pay.</p>

 <h3 id="tocanch11" class="tvis">Editing the sounds</h3>
-<p>The best thing about SD-80 is its editability. Neither SD-90 nor SD-20 came with the same level of editability upon launch. <a id="n7" href="#note7" class="note">[7]</a></p>
-<p>As claimed by the <a href="https://www.soundonsound.com/reviews/edirol-SD80">Sound On Sound review</a>, the editor for SD-80 is very similar to the one for XV-2020. The editor exposes a generic sample-based synthesis engine quite comparable to the one found in HALion (with more restrictions, of course). It lets you take full control of the synthesis engine and even create new patches not found anywhere else.</p>
-<p>The synthesis engine consists of four layers (with up to two samples <a id="n8" href="#note8" class="note">[8]</a> for each layer, plus frequency modulation), four filters (one for each layer), eight envelope generators (amplitude EG and filter EG for each layer), two LFOs <a id="n9" href="#note9" class="note">[9]</a> and a 4*4 modulation matrix. There are also 90 post-processing effects (some of which are combinations of multiple simple effects, hence the name ‘MFX’) to choose from for each channel.</p>
-<p>Restrictions aforementioned include inability to use external samples so you are essentially locked in to 589 built-in waveforms (which is probably fine because it’s not what the STUDIO Canvas line is aimed at), limited number of envelope nodes, limited modulation routing, restricted number of different MFX’s that can be used at the same time (3).</p>
-<p>The editor has quite terrible user experience. Guess it’s common for such decades-old software. It comes with a twenty-page pdf manual (which contains a lot of excerpts from the XV-5080 owner’s manual), which focus on the internals of the synthesizer, and a html manual, which focus on the interface of the editor.</p>
-<p>I’ve also tried editor software for other STUDIO Canvas modules using the same generation of XV engine. The SD-20 editor works seamlessly with SD-80, and it only offers basic parameters editing just like TTS-1. The SD-90 editor, despite being extremely similar to the SD-20 editor, doesn’t work at all, which is not surprising as it’s essentially the SD-20 editor plus an editor for the audio mixer and audio effects processor found in the SD-90, which the SD-80 lacks.</p>
-<p>By the way, if you have hi-dpi display and use Windows 10, be sure to use ‘System (Enhanced)’ scaling behavior for the SD-80 Editor. It scales perfectly that way.</p>

 <h2 id="tocanch13" class="tvis">Quirks</h2>
-<p>The SD-80 is GM2 compatible. However many midi files you randomly find may not play on it even when the device is in GM2 mode. If the midi file being played has any sort of bank selection event not recognized by the SD-80, the corresponding part will produce no sound at all.</p>
-<p>If your midi file has NRPN messages, things will get even worse. These things are essentially undocumented for the SD-80. All I could say is good luck keeping your eardrum intact. <a id="n10" href="#note10" class="note">[10]</a></p>
-<p>The manual says ‘This set (“classical” set) is also used when GM2 data compatibility is important’. However upon receiving the GM2 on message, the module automatically selects ‘contemporary’ set for every part. It seems impossible to change this behavior.</p>
-<p>The XG Lite mode has way more instruments available than what the manual has listed. Bank 18 patch 1 gives you ‘Piano 1d’ (presumably ‘Mellow Grand Piano’ in XG specification), which is not listed in the manual. It actually has 489 normal patches, 49 sfx patches, 2 sfx kits and 9 drum kits <a id="n11" href="#note11" class="note">[11]</a>. It’s quite irony to find out that they have more patches for their competitor’s standard than their own legacy standard. However these sounds are relatively lame when compared with authentic YAMAHA XG synthesizers of the same period. Particularly some sounds in different variant slot of the same patch number sounds almost identical. Roland obvious put less effort in these sounds in terms of sound designing.</p>
-<p>MIDI timing messes up if events flood in within a demisemiquaver worth of time. This quirk resembles the problem QMidiPlayer for Windows suffered from in its early days. But I’m pretty sure the cause is completely different. <a id="n12" href="#note12" class="note">[12]</a> Also this could be a common issue of old MIDI devices, as my old YAMAHA keyboards does the exact same thing.</p>
-<p>The sound generated by the SD-80/90 is phasey as could be heard in ZUN’s early works. If unsure, take a look at the spectrogram.</p>
-<p>The module, as all electric appliances do, generates heat. The manual says “A small amount of heat will radiate from the unit during normal operation”, and the chassis do get quite warm even when it is completely idle. This didn’t become an issue until later.</p>
-<p>Finally there are a couple of quirks in Roland’s former partner Cakewalk. Whenever the input signal level exceeds 0dB, instead of clipping the audio, it produces a loud cracking or popping sound in the record. Cubase and arecord have no such problem.</p>
-<p>Another quirk with Cakewalk is its metronome. Metronome settings in Cakewalk is saved on a per-project basis and there’s no way to change the default value (unless creating a template, which is useless for existing projects). By default it sends the metronome to the default MIDI device, which result in records with metronome clicks in them.</p>

Also I observed that all modules supporting 32 parts and 128 polyphony have two of these chips in them, while the ones with only one chip only supports up to 16 parts and 64 polyphony.

At that point, I was desperate to dive into it. So I simply tried all button combinations consisting of one to three buttons. The result didn’t let me down.

 <h2 id="tocanch20" class="tvis">Verdict</h2>
-<p>The SD-80, a product in Roland’s more budget-friendly Sound Canvas (Studio Canvas) line up, is a great sound module mainly focused at standards compliance at its time. In my opinion it’s the direct successor of the SC-8850, while the SD-90 is the direct successor of the SC-D70 (both are audio interfaces with a sound module integrated).</p>
-<p>The Studio Canvas family is Roland’s first and last line up of sound modules that map nearly all instruments to the GM2 instrument map. While making the instrument mapping less confusing, this instrument mapping has its limitations. No later Roland sound module does the same thing.</p>
-<p>Hardware wise, the SD-80 is extremely close to the XV-5080. But the SD-80 being a ‘Rompler’, its hardware capability is severely limited by Roland by matching them with worse wave ROM contents than its professional counterpart. This seems to be true across almost all professional and budget-friendly Roland synths in the 90s. (SC-88 has the same tone generator as JP-1080 (‘XP’), SC-88Pro has the same tone generator as JP-2080 (‘XP3’). SC-8850 and SC-8820 use a newer revision of the ‘XP’ chip (‘XP6’), which seems to be unused in a professional product.)</p>
-<p>Roland no longer makes ‘romplers’ today. Due to their unique sounds, these canvases might become a collector’s item in the future.</p>
-<h2 id="tocanch21" class="tvis">Things to do besides imitating ZUN</h2>
-<p>The SD-80 does not like QMidiPlayer very much. So the first thing to do is quite clear.</p>
-<p>Giving it a total makeup is the second thing on my bucket list. I’ll probably ditch the original top cover and front panel altogether and make some custom acrylic glass parts for it.</p>
-<p>Porting Linux to it might be a very fun (also atrocious) thing to do. The internals of the SD-80 is capable of doing much more than what it does as a STUDIO Canvas. It’s got the same main processor as the MC-909, just think about the possibility out there (this is also the reason why I call it a ‘trapped beast’ in the title of this post). The only thing against this is that I am shy of any experience with this level of hardware hacking.</p>
-<p>Setting up a web service where people upload their midi files and have them rendered with the SD-80 also sounds pretty cool. But I’m afraid I’ll receive something from Roland by then and it wouldn’t be fine for me. Is it really illegal to use a instrument on a time-sharing basis?</p>
-<p>Seriously though if I could pull it off, I’ll probably add a donation button and buy more classic sound modules for the site. Eventually it will turn into an online museum for sound modules… screw it I’m talking utter nonsense again.</p>
-<p>Also somehow extracting the waveforms and creating a instrument bank for HALion or Kontact is tempting. But the odds of being sued by Roland is even higher even though they did not explicitly disallow sampling their early products. To be honest I found it disturbing about the sampling restriction on these ‘unconventional’ instruments.</p>

 <h2 id="tocanch22" class="tvis">Newer Roland sound modules?</h2>
-<p>Newer Roland sound modules such as SonicCell and the latest INTEGRA-7 seems to maintain the compatibility with their original ‘XP’ synthesis engine to some extent – as they all support SRX expansion in a certain way. The synthesis engines are obviously improving over the years as Roland says the SRX expansion sounds built into INTEGRA-7 will sound a little different compared to earlier modules.</p>
-<p>However, disappointment strikes as soon as I saw the ‘READ’ button on screenshots of the editor software for the INTEGRA-7. I felt Roland really need to make more use of the USB bandwidth: the presence of that button implies the editor software still can’t reflect the realtime status of the synthesizer. <a id="n17" href="#note17" class="note">[17]</a> This is a huge drawback of using a hardware synthesizer that Roland still fails to fix to this day.</p>
-<p>Also, the INTEGRA-7 is super expensive for an amateur and Roland ended their budget <a id="n18" href="#note18" class="note">[18]</a> SOUND Canvas / STUDIO Canvas product line years ago. So no more Roland sound modules for me I guess.</p>

 <h2 id="tocanch23" class="tvis">Trivia</h2>
 <ul>
-<li><p>A XML file in the SD-80 editor (Script/SD-80EditorScript.xml) contains patch list and wave list for all SRX expansion cards, confirming the fact that the editor is based on an editor for some other sound module with expansion slots.</p></li>
-<li><p>There are two crystal oscillators on the main board of SD-80. X1 is a 24 MHz one and X2 is a 16.934 MHz one. Both are out of range of SH7706’s allowed external clock frequency (clock mode 0 has a input range of 25 MHz to 66.67 MHz, clock mode 1 has a input range 6.25 MHz to 16.67 MHz). MC-909, which has the same CPU as the SD-80, has a 16 MHz crystal as the CPU clock source and the CPU operates at 128 MHz. There’s also a 16.934 MHz crystal in the MC-909, which is tied to its tone generator (the same tone generator as the one inside SD-80, RA08-503 or ‘XV’). X2 in SD-80 is also very close to one of its tone generator chip. My blind guess is that the output from X1 in SD-80 goes through a frequency divider and the CPU operates at 96 MHz. XV-5050 also has a 16.934 MHz clock source tied to its XV chip. XV-5080 however doesn’t have a 16.935 MHz crystal directly tied to its XV chip, but rather a 11.2886 MHz one going through a 3:2 PLL producing a 16.9329 MHz clock.</p></li>

+<h2 id="tocanch0" class="tvis">A few notes upfront…</h2>
+<p>This post was supposed to come out as soon as it was finished. Well
+it looks complete but for some reason I couldn’t remember, I never made
+it public. Published 2024-02-17 without further modification.</p>
+<p>Original post starts below.</p>
+<p>If you are still unaware, the title is just sarcasm. As far as I
+know, the division I was working for does not work on any spyware.</p>
+<p>Also, this article is <strong>not</strong> approved by the propaganda
+division whatsoever. Everything is straight up garbage.</p>
+<h2 id="tocanch1" class="tvis">The Decision</h2>
+<p>As I have made up my mind to ‘strategically’ delay my graduation by a
+year, I initially hoped for taking the following months off and I did
+not plan for my graduation thesis at all. Therefore I intentionally
+skipped the subject selection process. All I wanted to do is chill for
+half an year and maybe make some contributions to several free software
+projects. Teachers noticed this and managed to persuade me to finish the
+graduation thesis this year. Only at this time did I realize how stupid
+I was – I am going to contribute to projects anyway, why don’t I take
+the chance to finish my thesis?</p>
+<p>However, as I have missed the opportunity to work on projects led by
+professors in my college, I had to look for intern jobs elsewhere. As I
+am not going to work for unethical companies, many companies my
+classmates are rushing into are not feasible for me. But actually I
+already have my choice in my mind: cause I am really interested in
+spying on how the ‘spyware corporation’ works on a daily basis.</p>
+<p>Finally, the choice was made. I tossed in my CV, which was put
+together in 5 minutes to them. Before long I got a quick reply. With
+everything settled down rather quickly, off I went.</p>
+<p>To sum it up, it was because:</p>
+<ul>
+<li>I was curious.</li>
+<li>I had plenty of time to waste.</li>
+<li>I wanted to get away from the campus I already spent 3 years
+in.</li>
+<li>with the additional benefit of finishing my graduation project.</li>
+</ul>
+<h2 id="tocanch2" class="tvis">The Workplace, the
+Colleagues and the Life</h2>
+<p>The workplace is nothing fancy. Dimly lighted, the work area is
+fairly cozy, possibly designed specially for us cavern-dwelling
+programmers. Computing devices are scattered throughout the enormous
+room, in which 90% of the local employees work.</p>
+<p>Co-workers here are competent to say at least (until they started
+rushing V20, as noted below). To list a few:</p>
+<ul>
+<li><a href="https://www.blumia.net/about.html">BLumia</a>: no more
+elaboration needed.</li>
+<li><a href="https://blog.justforlxz.com/about/">Kirigaya</a>: a little
+bit mean, a little bit naughty, but still nice guy to chat with.</li>
+<li><a href="https://github.com/zccrs">zccrs</a>: damn this guy
+definitely knows what he is doing when reviewing my shitty code. Rumors
+has it that he was once a wizard working for Nokia.</li>
+<li><a href="https://hualet.org/">Hualet</a>: that one who interviewed
+me. Passionate about free software. We talk quite a lot in private.</li>
+</ul>
+<p>Life quality in Wuhan was not a huge degradation compared to that of
+my university times, I’d put it that way. Commute times weren’t super
+long, foods here are nice (at least it rids me of the same kind of foods
+I had to have everyday on the campus), also I could for the first time
+cook for myself.</p>
+<p>Stereotype of the climate in southern China was broken: your clothes
+<strong>will</strong> be able to dry within a day, and you couldn’t
+really squeeze water out of the air.</p>
+<p>Public transit in Wuhan was tolerable until you got out of reach of
+the metro: the bus service was <strong>horrendous</strong>. There was no
+indication of where the actual station was, and the bus stops randomly
+‘roughly around’. I tried it once and dreaded having to take a bus ever
+since (fortunately, I didn’t).</p>
+<p>I lived in a rental room provided by Ziroom, which is essentially an
+apartment rental service broker. The apartment was shared by 5 persons,
+from which formed 2 couples, and … you guessed it, me. The room was
+relatively small (around 14m<sup>2</sup> in area), but super snug
+compared to my dorm in university. The real reason I find it that way,
+however, could ultimately be the fact that I was the only one inside and
+could do what ever I want.</p>
+<p>Interactions with roommates were minimal. In fact, I intentionally
+avoid interactions with my roommates because I was that type of a
+person.</p>
+<p>By the way, cooking is really deep a rabbit hole and I’m just getting
+down into it.</p>
+<p>All in all, it was a freshing experience for ‘an extremely spoiled
+child’ (as all my family members told me). I had fun, and I came back
+with every body part intact. I’m content with it.</p>
+<h3 id="tocanch3" class="tvis">My work</h3>
+<p>I mainly worked on the following things:</p>
+<ul>
+<li>Adding basic optical disc authoring functionality to the file
+manager.</li>
+<li>Move network configuration in the control center to the new code
+base.</li>
+<li>Giving the computer view in the file manager its new look.</li>
+<li>Random bug fixes in the file manager.</li>
+<li>A small portion of utility classes in DTK.</li>
+</ul>
+<p>There’s a lot of other miscellaneous stuff I did, some of which
+involves seizure-inducing programming languages
+<a id="n1" href="#note1" class="note">[1]</a>. I’m not going to list those things here.</p>
+<p>Actually, I promised to help revamping the infrastructure when I
+entered Deepin, mainly to improve its transparency (like Debian).
+However…</p>
+<ul>
+<li>They didn’t care.</li>
+<li>I wasn’t given time to do anything about it.</li>
+<li>I barely learned enough about how the current infrastructure
+works.</li>
+</ul>
+<p>And the promise was thrown straight out of the window.</p>
+<h3 id="tocanch4" class="tvis">Payment</h3>
+<p>Now looking back, I guess I was basically free labor <a id="n2" href="#note2" class="note">[2]</a> , donating my time to Deepin. I
+literately don’t care though, because I didn’t came for the money. It
+could be cringe-inducing to say, but their payment actually exceeded my
+initial expectation.</p>
+<p>By the way I actually even saved up a couple thousand during my time
+there. (Setting aside the fee ETS charged me for TOEFL and GRE of
+course. Those are nothing but f*cking cash grabs.) Guess it’s due to my
+extremely thrifty (stingy even) nature <a id="n3" href="#note3" class="note">[3]</a>.</p>
+<h3 id="tocanch5" class="tvis">Final Days &amp; The days after</h3>
+<p>I made my final commit on November 15th, and ended my internship on
+the same day.</p>
+<p>I stayed in Wuhan for another 30 days intermittently, finishing my
+final TOEFL test, visiting places, meeting with people, and most
+frequently of all, chilling in my ‘secret bear den’ (which refers to my
+rental room, obviously). Quite shockingly, I somehow managed to keep
+basically the same sleep schedule as the one before my internship
+ended.</p>
+<p>I returned home on January 3rd, and I was as lucky as one can ever
+be, cause all the coronavirus shenanigans just started to cook up.</p>
+<h2 id="tocanch6" class="tvis">Shitty Code</h2>
+<p>Never have I felt so involved with a programmer humor post until I
+have to actually deal with an old code base.</p>
+<h3 id="tocanch7" class="tvis">pasteFilesV2 also deletes
+file</h3>
+<p>When called with some obscene parameters, this function actually
+delete a file. What the hell.</p>
+<p>Even my code is arguably less shitty in this regard.</p>
+<h3 id="tocanch8" class="tvis">Practically no coding
+conventions.</h3>
+<p>Mixing tabs and spaces. Different indentation conventions.
+Incompatible naming schemes and even misspelled words in identifiers.
+You name it.</p>
+<p>In fact, deepin does have coding conventions, as listed <a href="https://hualet.org/blog/2019/07/23/deepin-qt/c-%E4%BB%A3%E7%A0%81%E9%A3%8E%E6%A0%BC%E6%8C%87%E5%8D%97/">here</a>
+and <a href="https://hualet.org/blog/2019/07/30/deepin-%E5%BC%80%E5%8F%91%E8%80%85%E8%A7%84%E8%8C%83/">here</a>.
+<a id="n4" href="#note4" class="note">[4]</a>
+Unfortunately, they are actively broken everyday in most projects.</p>
+<p>In defense of deepin though, this problem bothers a lot of other open
+source projects as well. My limited experience working with KDE’s
+codebase has already exposed that at least parts of KDE (namely
+libksysguard) suffers from the same problem.</p>
+<h2 id="tocanch9" class="tvis">Weirdness, quirks and
+other strange things</h2>
+<h3 id="tocanch10" class="tvis">“Developers’ lives matter!”</h3>
+<p>C’mon. If you have to equip your developers with computers that have
+inferior specs than your system requirements, don’t expect them to be
+super productive.</p>
+<p>Of course I understand they are currently under a rather tight
+budget, but they are offering quad core Core i5 to testers and new
+employees (some of which are quite incompetent, as described in the next
+section).</p>
+<p>Also, they refrain to provide necessary hardware for development.
+When I was adding optical disc authoring functionality to the file
+manager, my request to have a dedicated external optical drive was
+denied for some bizarre reason, and I had to share two optical drives
+with the testing department and the technical support department. This
+significantly hindered the development of the said feature, until I
+found a spare internal drive in the warehouse.</p>
+<p>Sometimes my friends there joked about the dessert as promised by the
+recruiter wasn’t being resupplied in time. For me, the dessert was
+really a surplus – I just want a computer that takes less than half an
+hour to build something!</p>
+<h3 id="tocanch11" class="tvis">Incompetent coworkers
+start to pop up</h3>
+<p>At a certain point of time (around June), I noticed a significant
+increase of personnel inside deepin. Many of these new employees are
+improperly trained. They don’t know how to incorporate git into the work
+flow (some know nothing about basic git concepts, or even about Linux at
+all), don’t look up documentation when troubled (instead they turn to
+CSDN <a id="n5" href="#note5" class="note">[5]</a> for help). As a result, the company had to spend
+extra time teaching them basic stuff, which to me seems a real waste of
+time.</p>
+<p>These incompetent employees are a major source of pain for project
+leaders. Some of them spent an entire day trying to figure out the cause
+of a very simple bug, without any level of success. Fortunately for
+deepin, most of them can reach some degree of competency after a few
+weeks of work (although they are still sometimes seen typing git
+commands from their notebooks).</p>
+<h3 id="tocanch12" class="tvis">“Designer-driven” development</h3>
+<p>This is a truly hilarious one. Here at Deepin (especially the project
+I’m personally working on, the file manager), product manager doesn’t
+decide what the program should be capable to do, the artistic designer
+does. The artistic designer almost has sole dictation on the
+specification of the product in this regard. We as developers can
+certainly dispute, but cases in which the designers changed their minds
+were rather rare, and most effort we made to persuade them was
+futile.</p>
+<p>By the way the current artistic designer is a very dedicated Apple
+fanboy. Expect some very Apple-ish bullshit in the next release.</p>
+<h3 id="tocanch13" class="tvis">Code review, or “code
+flattery”?</h3>
+<p>Code review is mandatory for every commit in Deepin. However policy
+of code review varied from people to people. The only one that really
+took it seriously was zccrs, who could almost always pick out the code
+where I screwed up <a id="n6" href="#note6" class="note">[6]</a>.</p>
+<p>On the other end of the spectrum was my friend, BLumia. His code
+review was usually just going through my code once, and seldom demand
+changes. At first I thought he was just giving me free passes, until I
+noticed obvious mistakes made by other coworkers that somehow slipped
+through code review. <a id="n7" href="#note7" class="note">[7]</a></p>
+<h3 id="tocanch14" class="tvis">Privacy issues?</h3>
+<p>I didn’t get to work on anything that actively connects to the
+Internet. So my position basically stayed the same as stated in my last
+article. To reiterate:</p>
+<ul>
+<li>They did a poor job dealing with public relationship.</li>
+<li>Telemetry should be off by default, or the user should be prompted
+whether they want it on installation.</li>
+<li>It’s free software though! You can check the code and strip
+everything unwanted.</li>
+</ul>
+<p>However, it’s probably getting even worse for Deepin (the
+distribution) users. I was told that an identifier of the user’s
+computer along with its specification might be used in the future. If
+you want to keep using DDE, but you still value your privacy, maybe
+consider moving to another distribution and install DDE there
+<a id="n8" href="#note8" class="note">[8]</a>.</p>
+<h2 id="tocanch15" class="tvis">Dick moves</h2>
+<h3 id="tocanch16" class="tvis">… as taken literally</h3>
+<p>As the amount of employees increases, space originally designated for
+everything else was re-purposed into work area. We had to move around
+while still working. Things were not looking good.</p>
+<p>Finally at the end of September, the company moved. This is regarded
+as the reaction to their increasing demand of workforces (as the old
+place has become very jam packed due to the sky rocketing number of
+staff), but it was also a very under-prepared dick move. Formal
+announcement of the move wasn’t published until the very last day. The
+new place is in the middle of nowhere and barely furnished. There are
+also two more completely empty floors, which are the source of later
+pains.</p>
+<p>The new place is much farther away, taking almost an hour by metro,
+or 40 minutes by commute shuttles. This forces me to get up a lot
+earlier, which is very disturbing. My overall life quality had
+definitely taken a punch after that.</p>
+<p>The place is actually bought from Huawei, who left a complete mess
+behind when they withdrew themselves from the place. Soon after we moved
+in, drilling and hammering sounds could be heard up stairs left and
+right. It was actually very nerve wrecking.</p>
+<p>As the company hasn’t yet settled down completely, many promised
+treatments are thrown out of the window. These include: desserts served
+during work hours (which are actually served as usual, but the amount
+didn’t increase as the number of employee rises. As a result, it’s
+basically gone.), monthly birthday celebration for employees, showering
+facilities, etc.</p>
+<p>This dick move made some of the coworkers staring to reconsider their
+life choices seriously.</p>
+<h3 id="tocanch17" class="tvis">Rushing V20</h3>
+<p>V20 is going to be the next major release of Deepin. Initially the
+planning for this release was rather relaxed: this major overhaul was
+projected to take about a year to mature, during which another one or
+two maintenance releases of the current Deepin 15 were planned. However,
+for some reason unknown to us <a id="n9" href="#note9" class="note">[9]</a>, the deadline was pushed back by a huge margin: now it’s
+expected to be released somewhere between Q4 2019 and Q1 2020.</p>
+<p>Now, suddenly the rapid increase of personnel makes sense. But I have
+to question the quality of the resulting software – and it’s not looking
+too good for them either. Many of the new applications suffer from major
+performance deficiency: one of the development snapshots of Deepin
+picture viewer takes more than two minutes to startup, and completely
+blacks out if the window is resized, the new archive manager can cause
+major lags on the file manager. Hell, even my own creation, the new
+computer view for Deepin file manager, suffers from some performance
+issues while resizing. But I simply didn’t have the time to address it
+completely.</p>
+<p>Wheels have been reinvented during the sprint, lots of them. In fact,
+it seems to be one of their goals to out-source no applications from
+other desktop environments. They even created a browser (based on the
+Chromium code base, of course) with the help from Qihoo 360 and an IME
+with the help from Sougou. I could give Deepin credit for the effort,
+but the quality of these wheels are questionable at best.</p>
+<h3 id="tocanch18" class="tvis">Lacking / bad community
+interaction</h3>
+<p>This is more or less the same thing as what I have already wrote in
+‘The “Deepin is spyware” problem’. But now that I have more insight, I
+could write more on this topic.</p>
+<p>Deepin is a for-profit company, feature requests from commercial
+customers always take priority. As the number of employees barely meets
+the need to develop those features, requests from the community are
+usually ignored straight away. Such filtering happens before the
+developers could see the feature requests – we won’t know about them
+unless we browse the support forum ourselves.</p>
+<p>The ‘designer-central’ process is very problematic too. In my
+opinion, Deepin’s chief designer is extremely self-centric, narcissistic
+even. This resulted in some very serious uproar in the community such as
+this one:
+https://github.com/linuxdeepin/developer-center/issues/1210#issuecomment-496341368
+Sometimes even the developers couldn’t put up with these design choices,
+and added hidden options for switching to something more sensible.</p>
+<h3 id="tocanch19" class="tvis">Illegal business practice</h3>
+<p>Namely, deepin-wine breaking GNU LGPL.</p>
+<p>Deepin has been distributing a fork of an outdated branch of wine
+without releasing the source code for quite some time, which is a very
+explicit disregard to wine’s license.</p>
+<p>They have promised to release the source code, but has yet to do so.
+In the mean time, wine has made three stable releases. So far they have
+only came up with a single justification: the fear of their domestic
+commercial competitors <a id="n10" href="#note10" class="note">[10]</a>‘stealing’ their hard work. If
+this bullshit stands for even a second, everybody on this planet would
+have been a drug dealer ’cause laws don’t do shit.</p>
+<p>To be frank, we have dozens of (L)GPL breakers here in China and we
+never stop producing even more of them. We have Allwinner and XiaoMi, to
+name a few. FFmpeg’s original hall of shame page would give you a even
+longer list, and you will find the names of some gargantuan Chinese tech
+companies in it.</p>
+<p>I don’t even think Deepin’s international acceptance has anything to
+do with its commercial success (or lack thereof). Do they even have any
+overseas commercial customers? If Deepin has really been a commercial
+success, I probably wouldn’t have to develop with a computer equipped a
+shitty Pentium that otherwise would find its home in the dumpster.</p>
+<h3 id="tocanch20" class="tvis">Restructure shenanigans</h3>
+<h3 id="tocanch21" class="tvis">Walking away from “the
+founders’ spirits”</h3>
+<p>This is definitely, definitely a huge misstep and a real deal
+breaker.</p>
+<p>IMO Deepin was once among the best meritocracy free software
+community in China. However with the changes applying to their roadmap
+since v20, everything started to disintegrate.</p>
+<p>Barriers were deliberately added to the community contribution
+process (the repositories on GitHub are now merely synced with internal
+repositories). Writing documentation was considered slacking (happened
+to me a couple of times), making the already terrible documentation
+situation even worse. They basically stopped even trying to make the
+development process transparent to the public.</p>
+<p>User’s freedom was thrown out of the window. Community edition now
+requires logging into an online account to enable root access, which is
+basically the first step to a complete vendor lock down. I imagine many
+users would resort to other distros and install DDE instead (if they
+still fancy using DDE in its new look and feel).</p>
+<p>Don’t get me wrong. DDE was (and still is) a beautiful desktop
+environment (even only superficially as some people might thought). It
+has followers who will use it no matter what. However, it demands a
+fork. A fork with its founders’ spirits in mind.</p>
+<h2 id="tocanch22" class="tvis">Epilogue</h2>
+<p>I’ve actually tried out the current public beta of Deepin V20 as of
+writing this section, and the majority of the issues I mentioned above
+still hold up. Grave performance degradation seems a lot less common
+though, although my shitty-performing computer view code has barely been
+touched since I left. A lot of applications are still in dare need of
+polishing. They’d better keep those commits flowin’.</p>
+<p>At this point of time I don’t even know what I was rambling about. It
+was 1:40 in the morning. Did I just typed over 15000 characters only to
+diss Deepin? Nope. Dwelling on our past success never makes us progress.
+It’s the reflection upon the mistakes we made that does.</p>

-<p>The 220V to 110V converter brick I have to carry around has been bugging me since the very first day I got my SD-80. Because the unit only consumes around 10 watts of power, I’ve always been dreaming of alternative ways to power it. When I first cracked my module open, I measured the power rails going out from the power supply unit: there is a ±15V pair, plus a +5V rail.</p>
-<p>My top candidate was a solution based around USB-PD. I’ve seen people modding their ThinkPads to charge through USB Type-C on r/ThinkPad, so I thought that module plus some DC-DC converter circuitry will do the job. I also had a fallback plan, which is basically to use any switching mode power supply that accepts universal voltage has two output rails (one positive and one negative), and stick some additional regulator circuitry to generate the 5V output.</p>
-<p>The USB-PD trigger module is actually very easy to come by nowadays, especially for someone in China. While others struggles to find these weird stuff on ebay and aliexpress, we just source them straight from taobao (which is essentially aliexpress for domestic users). There are even ready-to-use multi-rail voltage converter modules out there (they are either based around LM337/LM317, or TPS543x). Finally I picked the (seemingly) most popular PD trigger module people use to mod laptops from YZXstudio, and an adjustable voltage converter module based around TPS5430. The pictures below are from their sellers.</p>

-<p>I also bought some basic tools for soldering (Chinese knock-off of Quick 936A, lead-based solder and solder wick – I was too dumb to remember purchasing any flux) to make sure I can do the modding in my dorm.</p>
-<p>I waited a few days for all packages to arrive. After that I tested every component I need and they worked just fine. It’s time to pull the trigger. I started with desoldering the AC input socket. That went decently smoothly. My confidence started to build up and proceeded to desolder the original SMPS module, which is a rectangular daughter board that has quite a few pins soldered on both sides of the board. Things went horribly wrong (particularly because I didn’t have any flux and the original lead-free solder refused to flow or blend with my leaded solder) and I started ripping tracks off the base board. Finally I decided it was an impossible task for me to desolder it without completely destroying both boards, so I simply drilled the pins out of the board. While the base board wasn’t totally destroyed, it was pretty close. I soldered wires directly to the components on the base board (because tracks on the other end have been ripped off). At this time my soldering job was just totally awful because I was pissed and it was super late into the night. Anyway, when I finally piecing everything together, it somehow worked.</p>
-<p>Next it was time to put everything back into place. I had the idea of designing a 3d-printed holder for the USB Type-C extension cable that fills the hole for the original AC socket, however I couldn’t even afford a proper 2d-printing setup, let alone a 3d one. So I have to scrap that idea for now. None of the screw holes on the converter board can fit the holes on the chassis, so I just taped the module down. It was a complete mess inside my SD-80 now, but at least everything still worked (until a couple minutes later). I did mention that I had the wish to make custom acrylic chassis for my SD-80 some day in the future, hopefully I can get this mess fixed by then.</p>

 <p>Of course this is undesirable. So I had to find a fix to this.</p>
-<p>Fortunately, nothing on the main board seemed to be hurt. I can just bypass the volume control and get the correct output on output 1 using some jumper wires. So the fault is contained in the volume board. I’ve basically sent -15V straight into the base of two transistors, but measuring those transistors didn’t reveal anything wrong with them. So I had to assume I have fried the amp chip (NJM4565). I got a few replacements (NJM4580, compatible spec-wise) from taobao, and replaced the “faulty” NJM4565 (still without using flux). But the audio output is still messed up and the opamp chip still gets very hot after the replacement. I decided to give up for now, and look into the thing later. Meanwhile I just tucked some of the wires from CN6 into CN7 so that I can still get analog output from output 1 on the back panel.</p>

-<p>Since I have always wanted to record my SD-80 through a digital link (even before frying the analog output), I have been keeping an eye on cheap digital recording solutions. Modern professional audio interfaces never come with digital input on budget models. Among the older interfaces, UA-25(EX) from Roland (EDIROL / Cakewalk) seems to be a reasonable choice. There are also a bunch of different models from various brands of the same era that have digital inputs. However these models are virtually impossible to get in China. Then some cheapo consumer grade stuff caught my attention – several relatively nameless brands have “sound cards” for home theater uses that have digital I/O. Those are priced at roughly 200~300 Chinese yuan. Among those I found a more widely recognized brand called Terratec. They have PCI-e and USB sound cards that comes with digital I/O and are available for purchase in China. Price are on the higher end (300+ CNY), however still way cheaper than the cheapest professional audio interface that doesn’t have digital I/O (those start from ~800 CNY). Plus these models seem to have a reasonable Linux user base, so I got their Aureon 7.1 USB.</p>
-<p>This thing feels extremely cheap on first sight, weights close to nothing, and is made entirely out of plastic. It comes with an extremely thin S/PDIF fiber optical cable which looks so fragile that a single touch may break it. It does work out of the box. ALSA recognizes it as “Aureon 7.1 USB” without further clue about the chip it uses, however the Windows driver is more telling. Its control panel associates the chip with a Taiwanese company called Cmedia, and the kernel driver is named <code>cm106.sys</code>. Upon further investigation this thing is likely to be based on their CM106 chip (which is an ancient solution from 2003), or its pin-compatible successor CM6206. I don’t have interest in disassembling it right now (update: confirmed by a teardown later. It’s indeed based around the CM6206), but either way it’s a cheap consumer grade solution.</p>
-<p>SD-80’s digital output is fixed at 44100 Hz sample rate. So the sound card must also record at 44100 Hz to make a correct recording (unless it has internal resampling). This is easily doable under Windows (just select the appropriate sampling rate in the device properties dialog). It’s also reasonably easy with Jack, where you can just start the server on that specific device with the correct sampling rate. But this is not that easy to achieve for pulseaudio. By default, recent versions of pulseaudio auto detects cards with the <code>module-udev-detect</code> module, which doesn’t allow setting a different sample rate for a single sound card. Setting <code>alternate-sample-rate</code> doesn’t work either because this card supports digital signals at 48000Hz which in my case is the value for <code>default-sample-rate</code>, and therefore would not fallback to <code>alternate-sample-rate</code>.

 <p>(This part is written Q4 2021)</p>
-<p>Yes I did upgrade to a UA-25 (non-EX). I got mine for about $60 (after a long struggle against eBay’s virtually non-existent customer service to lift a stupid suspension on my account).</p>
-<p>Gentoo Linux handles this new interface without any problem. The troublesome part is Windows (again). Just like the SD-80, Roland didn’t release any Windows 10 driver for the UA-25. <a href="https://chrisoft.org/blog/post/2019-04-25.html#tocanch4">The trick</a> I used to make their SD-80 Windows 8/8.1 driver install on Windows 10 worked fine, and the driver installed correctly. But things quickly went down hill. Whenever I open an application that uses ASIO, the driver freaks out and causes audio dropouts like crazy. This glitch makes the driver basically unusable.</p>
-<p>I tried drivers for different Windows versions. Nothing changed. When I was desperate and searching around the web, I discovered that UA-25EX has an official Windows 10 driver. UA-25EX is virtually the same as UA-25 except it comes with an improved limiter section which I assume has largely nothing to do with the driver. So I decided to try some “mad hax”.</p>
-<p>Windows driver for UA-25EX is only available from Microsoft as a Windows update package. Roland says if you have a UA-25EX, the package will automatically install itself once you plug it in. But I don’t have a UA-25EX: I only have a UA-25. So I had to go to the Windows Update Catalog, looked for the driver package there, and download the build for my computer (which turned out to be much harder than it needs to be, but I won’t go deeper into that here). I extracted the package, and modified the USB product ID the driver is designed for in the INF file:</p>

-<p>Just change <code>PID_00E6</code> to <code>PID_0074</code> (and also the comment if you wish). AND IT FRICKING INSTALLED. ASIO also worked perfectly. (Insert a thousand-word essay trashing Roland’s bad practice here.)</p>
-<p>So did the upgrade work? Nope. The DC bias is still there. Now it’s more likely that the DC bias is from the SD-80 itself. Also another very telling clue is that when the sound generator inside the SD-80 is reset, the DC bias immediately goes away. I did some additional research on the Internet and discovered people have theorized that the DC bias is from the effect processor. They are having a <a href="https://gearspace.com/board/electronic-music-instruments-and-electronic-music-production/1302162-roland-xv5080-spdif-issue.html">similar problem</a> with their XV-5080 and XV-5050 as well, both of which have the same synth engine as the SD-80. By replicating their experiments and getting the same result, I personally conclude that the DC bias comes from the amp / gain / filter section of the integrated effects processor. So I guess I’ll have to keep using high-pass filters on the output for now.</p>
-<p>So the only upgrade is that now I can record S/PDIF signal with native ASIO. Besides that, it’s actually a downgrade: Output from the computer will be muted if the digital input of the UA-25 is enabled. This forced me to keep using the analog input for monitoring.</p>

-<p>Kalas was extremely keen on preserving the sounds of SD-90/80 during our communications. I have the intention to keep these legendary Roland sounds around long into the future as well. We discussed the following possibilities. Note that due to the locked-down nature of SD-90/80, we referred to them mostly as “Romplers”, but these methods listed below apply to those expandable models as well, especially considering they are nothing but romplers that you can add more ROMs to, and the architecture of Roland’s PCM synth.</p>
-<p>In this section I’ll start using the word “SD-90” and “SD-80” interchangeably, and by saying “SD-90”, I’m actually referring to the synthesizer module built into it. If Roland was being honest when they were saying “the newly developed multitimbral MIDI sound module, as built into the well-received SD-90” when they were introducing the SD-80 <a id="n3" href="#note3" class="note">[3]</a>, it should be safe to assume they are virtually the same thing. I know this is kind of sloppy. If you want to read more on this, checkout the <a href="#tocanch33">“More on SD-80 vs SD-90 vs SD-20”</a> section.</p>

Indeed there are a couple of sound modules / synthesizers that has been emulated with reasonable success. <a href="https://github.com/munt/munt">Munt</a> has an amazing emulation of Roland’s LA synthesis found in the MT-32 or D-50. <a id="n4" href="#note4" class="note">[4]</a> Yamaha’s FM synthesis chips have been reverse engineered from inside out: there are <a href="https://github.com/gtaylormb/opl3_fpga">implementations on FPGA</a>, multiple nearly perfect software implementations, and other bizarre stuff.

-<p>However, I personally don’t think emulation is the way to go for SD-90/80. The success (or lack thereof) of these emulated models does have their reasons:</p>

Roland has never made their synthesizer chips available to third-party vendors, and therefore it’s impossible to take advantage of public datasheets.</li>

 <li>They are relatively sample.</li>

 </ul></li>
-<li>Most emulated sound modules in MAME have been a failure in terms of real-world usability. The emulated MU-series either freezes, produces no sound at all, or makes loud unexpected noise when playing the demo track. The SC-55 emulation barely works – they only got the CPU working and running its dumped control ROM. Please don’t get me wrong: the fact that some emulated MU model could make any sound is almost a miracle for me, and definitely a huge achievement despite the far-from-ideal results it currently has, as Yamaha’s sample based synth chips (<code>GEW/SWP</code> stuff) are no easy nut to crack. This approach is highly unlikely to work for the SD-90/80 because unlike gaming consoles, getting the CPU to run its system code doesn’t mean much for synthesizer emulation. It’s the emulation of the actual synth/DSP chip that matters. And the XV chip found in SD-90/80 is a <strong>monstrosity</strong> compared to the early SWP chip in the MU-series. For this reason, I find a pure emulation based solution difficult to implement for SD-90/80.</li>
-<li>Munt is successful because instead of an instruction-to-instruction emulation, it’s more like a software reimplementation of the LA synth. It doesn’t try to run the control ROM on an emulated Intel 8098 CPU, but instead only use it for determining some characteristics of the software implementation of the LA synth. This approach makes the most sense when trying to recreate SD-90/80 in software form, but still definitely require tons of reverse engineering (either blackbox or whitebox).</li>

 <h3 id="tocanch8" class="tvis">Sampling the Rompler</h3>
-<p>Many people have attempted to sample the SD-90. We already have the (in)famous THFont from forever ago that contains some samples from the SD-90, plus <a href="https://musical-artifacts.com/artifacts/1367">these</a> efforts to create a complete set of sampled instruments from the SD-90. However, these folks aren’t doing it in the most efficient way IMHO. Since the SD-90/80 is extremely editable, one can craft presets ideal for raw sample extraction (no filters, no LFO, just a plain tone with a constant amplitude envelope). Since many preset instruments in the SD-90/80 consist of multiple layers using different samples, instead of sampling the patches, one can sample every individual waveform and layer the samples in a way similar to the original presets to make close imitations of SD-90/80 instruments. If done properly under ideal conditions, the resulting sample library should be around the same size of SD-90/80’s sample ROM, but decompressed (my guess is ~64 MiB <a id="n6" href="#note6" class="note">[6]</a>).</p>
-<p>If you’re only going to use the vanilla SD patches without any sort of modification (including filter response, envelope, and effect parameters), those existing samples will work just fine and they are probably the most accurate out there if recorded properly. Of course, the “efficient” approach of sampling sacrifices some level of that accuracy (due to a different engine being used for playing back the samples). But in exchange you get the highest level of freedom to recombine the raw samples into custom patches including tweaking all possible parameters and effects available in the synth engine of your choice (which is a huge plus for me personally, as I love to create whacky patches).</p>
-<p>One problem for extracting the samples is that, a single waveform in the SD-80 may contain different samples assigned for different key ranges. This is often called a “multisample” by some sources. The way the samples are mapped to the keys must be figured out before actually sampling them. I have written a small(ish) python script to do exactly that. It records the SD-80 playing two different keys at the same pitch one after another, and compare them by calculating the correlation. If the correlation is lower than a threshold, the two keys use different samples. This approach works reasonably well for most samples, but for a few analog synth samples, it works poorly. For those samples, I had to resort to relying on the human ear (DTW, dynamic time warping, is also used sometimes, but it usually has poor results for these samples as well). Also the XV engine have some weird quirks near the keys C7-D8 (96-110). The actual waveform produced within that range varies very slightly from time to time. This is possibly due to the effect of <a href="https://en.wikipedia.org/wiki/Aliasing">aliasing</a> becoming prominent for these high-pitched notes. I have already figured out key-sample mapping for all multisamples (they are not guaranteed to be correct, due to reasons mentioned above).</p>
-<p>Another problem is looping. Roland uses sample looping extensively in their PCM synths. It’s basically their secret sauce to squeeze thousands of instruments into a unit with only tens of megabytes of samples. Sample loop points can also be computed using cross-correlation. But is nowhere near perfect. Of course it can be done manually, but that would be a tedious task.</p>

 <h3 id="tocanch9" class="tvis">Dumping and Deciphering</h3>
-<p>The wave ROM in the SD-80 is a standard part despite the custom Roland engravement on it <a id="n7" href="#note7" class="note">[7]</a>. This is expected because Roland has been using standard mask ROM parts from various manufacturers for the wave ROM. This means the content of SD-80’s wave ROM can be easily dumped.</p>
-<p>This might be shocking for some of the readers, but Roland does compress their samples. This is evident from the specification of XV-5080 “Wave memory: 64MB (16-bit linear format)” while the XV-5080 only has 32 MiB wave ROM. The compression, previously unknown to me, has been identified to be a variant of the differential pulse-code modulation (DPCM) called FCE-DPCM by <a href="http://www.dtech.lv/techarticles_roland_exp.html">some amazing person</a>. The same person seemed also figured out the structure of the wave ROM used by sample-based synthesizers from Roland of that general era. Unfortunately, I wasn’t able to find the article on the technical details of the compression method at the time of writing. Anyway, hats off to Edward of dtech.lv!</p>
-<p>I <strong>will surely</strong> make a dump of the wave ROMs of my SD-80. However, I want to do it in an nondestructive manner – I don’t want to get a ROM dump and an unusable SD-80 (or end up with no valid ROM dump and an unusable SD-80). Since I have proved my SMT soldering job is terrible and shall never be in the vicinity of a SMT board holding a soldering iron or hot air gun, I might try some clipping the chip instead. I’m considering to try <a href="https://www.360-clip.com/uni-48.htm">this</a> clip from 360-clip. It claims to be applicable to any 48-pin TSOP chips. If that’s true, with the help of this clip and a Raspberry Pi <a id="n8" href="#note8" class="note">[8]</a>, I can suck that juicy content out of the wave ROM chips of the SD-80.</p>
-<p>Once we have the ROM dump, we can start trying to figure out its structure. If we somehow managed to do that, we would be able to feed the decompressed samples together with the already dumped patch parameters to some existing or new, custom sample-based software synthesizer, and achieve decent results mimicking the SD-90/80. Patches that make use of MFX would certainly be a pain to deal with. However one can always simulate MFX with external DAW effects. To hear the difference MFX makes for various preset patches that use it, see the <a href="#tocanch37">“What role does MFX play?”</a> section.</p>
-<p>I believe this approach is very similar to that one used by Munt (although I only read a small part of Munt’s code base, and I didn’t read anything about their reverse engineering approach). The SH3 CPU plays a relatively minor part in the tone generation of SD-80. Instead, we should focus on replicating the sounds of the XV engine. Also, an logic-level reverse engineering of the XV chip doesn’t seem reasonable because it’s such a huge and complex chip (or rather, a huge gate array). Just save the hassle, treat it like a blackbox and try to reproduce its output using a software implementation should be able to produce acceptable result on its own.</p>
-<h4 id="tocanch10" class="tvis">Extra rambling about the ROM chip</h4>
-<p>In the part number of <code>μPD23C128040ALGY-***-MJH/MKH</code>, the <code>***</code> part is the ROM code. When a mask ROM chip is commissioned, the customer (Roland in this case) needs to submit the desired ROM content and their choice for various other options (in case of <code>μPD23C128040ALGY</code>, they can choose how the logic level on a certain pin controls the outputs). The manufacturer then arrange the mask according to this information and assigns a ROM code to this specific mask <a id="n9" href="#note9" class="note">[9]</a>. Therefore, for two chips of the same type, if they have the same ROM code, their contents should be identical. This way we can guess with fair amount of certainty that the XV-3080, XV-5080 and XV-5050 have identical wave ROM contents (they all use <code>μPD23C128040ALGY-849-MJH</code> and <code>μPD23C128040ALGY-850-MJH</code>).</p>
-<p>Among the chips with Roland markings in the SD-80, the XV chip and 8-bit MCU with Roland-programmed ROM has other markings that matches Roland’s internal part numbers (the numbers with a prefix R, like <code>R01455956</code> and <code>R02902867</code>), and followed by a indicative part number of the actual chip (<code>137</code> and <code>RA08-503</code>). However, none of these features matches on the wave ROM chips. The wave ROM chips has internal part number <code>R02678601</code> and <code>R02678612</code>, while the numbers on the service manual are <code>03010612</code> and <code>03010623</code> respectively. The indicative part also doesn’t match either: the chips in my unit have <code>23C128L-529J</code> and <code>23C128L-535K</code>. While the J/K variant and the <code>23C128L</code> part does match, what I presumed is the ROM code doesn’t (529 vs 525 on IC28, 535 vs 526 on IC29). What does this mean? I don’t really know. My SD-80 is built relatively late into production (date code on the main board is 2004-08-27, date on the service manual is May 2002 – when the SD-80 was initially released). Maybe Roland did revise the wave ROM content. If that’s the case, it would be interesting to find one with the original ROMs and compare them. I wouldn’t expect there to be any significant differences, though.</p>

-<p>The executable contains references to “Automation”, “User Rhythm” and such. Apparently they still left some code from the plugin version of the HQ engine in this converter.</p>

 <h3 id="tocanch15" class="tvis">Roland Cloud</h3>
-<p>Roland has been pushing their subscription service “Roland Cloud” since 2018. When it first came out there was no plugin of my interest. The deal breaker for me back then was there was no permanent licensing option. If you know me, I’m strongly opposed to the subscription model used for software products.</p>
-<p>Starting from May 2020 though, Roland started offering “lifetime keys”, which now puts this service within my radar. I took the ultimate tier trial and installed every piece of plugin replicating SRX boards and the XV-5080, as well as the then-new “Zenology” synth. I’ve got mixed results.</p>
-<p>The software aspect is okay. It’s much better than SoundCanvas VA I’ve used years ago, which has glitchy TVA and TVF and was never fixed. The user interface scales perfectly on high DPI screens. Editing experience of the SRX/XV plugins is basically the same as the editors for later Roland PCM synths (such as the SonicCell and the Integra-7) – that is, much better than the original XV or SD-80 editor. These plugins still have terrible performance as most previous Roland software synths do (each instance needs plenty of processing power – if you use a computer that predates the release of these plugins, the performance will probably suffer).</p>
-<p>The sound is … fine? Didn’t give me the same astonishment when I heard a real XV-5080 on YouTube though (I thought “no way this thing only has 32 MiB of sample content!”). For most patches, they sound “close enough” to an actual XV-5080, despite a handful of caveats. The synth engine do behave nearly identical to actual XV-based synths, at least according to my tests. The XV-5080 plugin is especially underwhelming, considering the original XV-5080 is expandable and can also load external samples. If only the XV-5080 plugin could load samples and patches from other SRX plugins installed, it would have been a lot better (although this is solved by Zenology, it has its own issues). The MFX uses a different set of effect types from the original XV-5080 and SD-80: they are modeled after synths after the Fantom-S era). However I’d say the effects bearing the same name as XV effects do sound largely the same.</p>
-<p>The executables contain a resource folder named “WROM”, and it contains the wave ROMs used by the plugins. They are all exactly 32 MiB. The wave ROM files contains a similar 32-byte header to dumps of actual wave ROM of earlier Roland PCM synths (see the JD-800 wave ROM dump from Edward of dtech.lv).</p>
-<p>I do have some major complaints though. Each executable contains a copy of the wave ROMs. If you choose to install all plugin formats, that will install 4 copy of exactly the same wave ROM on your computer. Also it’s impossible to combine the sounds of different SRX boards. Most samples originated from Spectrasonics are missing from the SRX plugins but are reincluded in the EXZ expansions which can be used in Zenology, indicating a copyright dispute between the two companies that was resolved later <a id="n11" href="#note11" class="note">[11]</a>. These problems can be partially solved if you use the newer Zenology plugin instead. But Zenology is riddled with its own issues. It uses a nearly entirely new set of MFX (identical to the MFX from their 2019 Fantom-6/7/8 workstations and other “ZEN-CORE” based products), and completely lacks reverb effects. Effects that have the same name in Zenology and XV-based synths doesn’t necessarily behave the same. And Zenology still can’t load samples from different sample groups to left and right channels of a single voice. I know it’s a thing in the original XV, but since it’s a software reimplementation, they don’t have to stick to the same restrictions do they? Also, why are all these plugins monotimbral? If your answer is “just use multiple instances”, I would remind you that these are Roland software synths, and they don’t perform well if you add multiple to your virtual rack…</p>
-<p>Recreating patches of the SD-80 using these plugins does seem to be possible, and there are already plenty of people doing that. See the section <a href="#tocanch32">“SD-80’s sound content”</a> for details. However it does still rely on proprietary Roland software products (which, if they want to, can cease the support at any time), requires pricy licenses, and on top of all that, a crappy authenticating system.</p>

-<p>From this point on the service manuals from Roland have become less useful. They stopped listing the ICs in their parts list. However the block diagram and schematics remain.</p>
-<p>Roland introduced the so-called “SuperNATURAL” sounds with their Fantom-G series, together with its new expansion board format (ARX). These boards has a CPU built on it (the same SSC7 CPU used in Integra-7). The CPU is connected to a set of RAM named “Effects RAM” in Roland service manuals. Fantom-G by itself doesn’t appear to have any “SuperNATURAL” sounds preloaded, and these new sounds clearly breaks some of the limitations of the old synth engines. This leads to my suspicion that the ARX boards have self-contained synth engines on board, and the new “SuperNATURAL” engine is either software based, or the SSC7 chip has some sort of extra bits that doesn’t belong to the CPU (that is, an integrated ASIC DSP block). The SSC/SSC7 chip is seen on all ARX boards, as well as the Integra-7.</p>
-<p>Along with this new CPU thing, there are new effect processors/DSPs: WSP and ESC2. WSP is found in a few relatively earlier (2009-ish) models, while ESC2 is appears in almost all post 2010 Roland synths (Integra-7, probably all Boutique models, and the latest Fantom-6/7/8 series). A single ESC2 chip is able to provide 16 individual effect slots in the Integra-7. However sometimes two of these chips can be seen in some of the Boutique units.

 <h3 id="tocanch32" class="tvis">SD-80 is an XV-5080 …</h3>
-<p>… locked into performance mode and with samples cherry-picked by Roland?</p>
-<p>Indeed, the address mapping <a id="n17" href="#note17" class="note">[17]</a> for the SD-80 is almost fully compatible with that of XV-5080. Even a lot of parameters that make no sense for the SD-80 are preserved: SD-80 has a parameter to select which wave expansion board to use, wave groups (which the SD-80 only has one), as well as parameters for “multi-partial” patches, which on the XV-5080 is a way to put together patches that use samples loaded into the RAM. Only the first one has its description changed to “reserved” in the documentation. The SD-80 doesn’t have any wave expansion board slots hidden inside, nor does it have support for external sample loading.</p>
-<p>Of course from the form factor side of things, the SD-80 looks more like a cut-down version of XV-5050 which is a full 1U rack unit while the SD-80 has a 3/4 rack design. However the SD-80 does retain XV-5080’s 128 polyphony and dual XV guts.</p>
-<p>What is called “Performance” in XV-5080’s address map is called “Multitimbre” in SD-80’s address map. They have the exact same content inside (well, not really exact – SD-80 has quite a few extra parameters in the “Multitimbre Common” section, mainly to expose some GM2 parameters and parameters that earlier SoundCanvases had in their address maps). On the XV-5080, you can save the performance to one of its 64 performance memory slots. Configuration of all 32 parts of the synthesizer is restored from the save slot when a performance is loaded. Just like the XV-5080, the SD-80 has a name assigned to its “Multitimbre”, which is set to “Native Mode” upon entering its native mode. But there are no memory slots for “multitimbres” in the SD-80, nor is the name of multitimbre shown anywhere (either on the LCD screen, or in the SD-80 Editor), rendering this name useless. This name is not read-only. You can change it as you wish using system exclusive messages, and is preserved until the next native mode reset message is received.</p>
-<p>Since the SD-80 is straight up the same when compared to the XV-5080 in terms of synthesizer engine, and also has extremely similar MIDI implementation <a id="n18" href="#note18" class="note">[18]</a>, the SD-80 can be seen as a XV-5080 with locked-down samples.

This is a huge step forward from the lame set of a few parameters offered by earlier GS models.

-<p>So the content of the SD-80 is actually a mixture of XV-5080, SRX wave expansion boards, SR-JV80 boards, earlier SoundCanvas patches and maybe a few new sounds. Reusing stuff isn’t surprising for Roland, nor should it be considered “bad”. They’ve been known to do this <a href="https://www.soundonsound.com/reviews/roland-sc88">since the early SC days</a>, where they used JV- and SR-JV80 expansion board sounds in the old SC series. Evidently, the waveforms come with XV-5080 itself include everything from the JV-2080/1080, which are in turn partially from the JV-880, and eventually from the JD-800… I’ve also noted that SuperQuartet has a substantial overlapping set of instruments with SRX-03. All I want to say in this section is that if you want to get some particular sounds from the Studio Canvas, instead of waiting for a second-hand offering, maybe look somewhere else.</p>
-<p>Since the content of SD-80 is mostly just cherrypicked XV/SRX content, it really doesn’t need any additional praise from me. However I think it’s worth pointing out that Roland’s samples of that era, just like sounds from most other vendors, are heavily looped. They have loop periods that are quite short (usually less than a second). They are also usually heavily preprocessed. As the amount of memory used for reproducing the instruments saw a huge boom in the 2000s, they no longer sound downright “fake” or “plasticky” compared to romplers from a decade ago. However when compared against huge modern sample libraries, most instruments from these 2000s Roland romplers sound more “idealistic” rather than “realistic”, just like your average Japanese anime girls with unrealistically huge eyes. Not saying that such sound is bad, though.</p>
-<p>The GS sounds and XGLite sounds of the SD-80 are completely trash. The GS sound set is pretty much just the SC-55 map in later SoundCanvas models using SD-80 samples. The XGLite sound set however, is notably larger than the average bottom-of-the-line Yamaha Portatones from the early 2000s (the XGLite instrument listing in SD-80/90’s manual is incomplete. Check my first SD-80 post for a complete list). There are probably only 5 or so usable sounds offered in these modes in total (most of which are in the XGLite sound set, which is kind of ironic for a Roland sound module). It’s not worth it to switch modes just for those sounds, especially since these modes don’t support low-level editing like the native mode.</p>
-<p>The SD-80 features 1050 instruments and 30 drum sets, which is a significant decrease from the last generation SC-8850 (1640 instruments and 63 drum sets). The loss of SC-8850’s ethnic and analog instruments is a shame. But the quality of instruments does receive a general uplift.</p>

Roland’s waveform compression scheme usually results in a ~50% compression ratio. Therefore the content is roughly equal to 64 MiB of uncompressed 16-bit PCM wave.<br></span><span class="TText"><a id="note7" href="#n7">[7]</a>: The “23C128” kind of gave it away – they are the <code>μPD23C128040ALGY</code> mask ROM chips from NEC, which is the exact same type of ROM used in XV-5080. Unlike the XV-5080 though, the SD-80 makes use of both its J variant and K variant, while the XV-5080 only uses the J variant (these variants have symmetric pin configuration). <br></span><span class="TText"><a id="note8" href="#n8">[8]</a>: Well, the Raspberry Pi isn’t really suitable for this task because it doesn’t have enough GPIO pins. But there’s an easy workaround for that.<br></span><span class="TText"><a id="note9" href="#n9">[9]</a>: For readers who wonders what “mask” means in this context: you can treat a mask ROM as a huge array of tiny switches that can’t be turned on or off once manufactured. You can access the state of a group of switches by giving an address to its input pins. The mask is used as a template of the states of these switches during the manufacture process. This is electrical engineering amateur Chris trying to explain mask ROM in layman’s terms.<br></span><span class="TText"><a id="note10" href="#n10">[10]</a>: HyperCanvas (HQ-GM2) or Cakewalk TTS-1, which is a rebranding of the former; SuperQuartet (HQ-QT) and Orchestral (HQ-OR).

Earlier SC models employs a GS-specific address map which looks nothing like their counterparts.<br></span><span class="TText"><a id="note19" href="#n19">[19]</a>: And also the last time, since neither the SD-20 nor the SD-50 has such editability.<br></span><span class="TText"><a id="note20" href="#n20">[20]</a>: Apparently it’s from the SC-8850.<br></span><span class="TText"><a id="note21" href="#n21">[21]</a>: The multisample from Roland Cloud seem to have an extra sample in the highest register, which sounds like it’s processed with a low-pass filter with very low cut off frequency and makes it sound like garbage. This is also the case for the version included in the original SRX-09 boards.<br></span><span class="TText"><a id="note22" href="#n22">[22]</a>: The owner’s manual of the SD-80 contains blatant lies. It says “It is not possible for the edited sounds to be saved in the internal memory of the SD-80” (which is directly copied from SD-90’s manual), and goes on to teach you how to save a user patch.<br></span><span class="TText"><a id="note23" href="#n23">[23]</a>: For example, nearly all acoustic bass patches have a disabled tone with wave number 249 “TenBlwSaxVib” selected, and the Fiddle 2 vib patch have a disabled tone with wave number 276 “Blow Pipe” selected.<br></span><span class="TText"><a id="note24" href="#n24">[24]</a>: Wave #249 in XV-5080 is UprightBs 2A, and Wave #276 in SRX-09 is Fdl Pizz 1C (Fiddle Pizzicato).<br></span></div>

+integrated circuit chips on SD-80 main board” in the first section.
+Roland’s waveform compression scheme usually results in a ~50%
+compression ratio. Therefore the content is roughly equal to 64 MiB of
+uncompressed 16-bit PCM wave.<br></span><span class="TText"><a id="note7" href="#n7">[7]</a>: The “23C128” kind of gave it away –
+they are the <code>μPD23C128040ALGY</code> mask ROM chips from NEC,
+which is the exact same type of ROM used in XV-5080. Unlike the XV-5080

+state of a group of switches by giving an address to its input pins. The
+mask is used as a template of the states of these switches during the
+manufacture process. This is electrical engineering amateur Chris trying

+of the former; SuperQuartet (HQ-QT) and Orchestral (HQ-OR). A plugin
+called GrooveSynth (P5antom) bundled with several earlier Cakewalk

+DSP power.<br></span><span class="TText"><a id="note15" href="#n15">[15]</a>: Support for multisamples also exist in Fantom
+S/S88, so this is more likely due to an updated system software rather
+than changes of the synth engine.<br></span><span class="TText"><a id="note16" href="#n16">[16]</a>: There is evidence that some of them

+&lt;-&gt; JV-2080, SC-8850 &lt;-&gt; XV-3080). However the second half

+multisample from Roland Cloud seem to have an extra sample in the

+This is also the case for the version included in the original SRX-09
+boards.<br></span><span class="TText"><a id="note22" href="#n22">[22]</a>: The owner’s manual
+of the SD-80 contains blatant lies. It says “It is not possible for the

-<p>No, it isn’t an XV chip. It’s an XP7 (RA0C-003) chip. This chip is also used by the bottom-of-the-barrel model in the XV line-up, the XV-2020. This is likely the final iteration of the codename XP. The CPU is a SH7016, same as SC-8850 and SC-D70. Other major chips include two 4Mbit EDO DRAM chips (one for CPU and one for XP7), a 16Mbit flash memory for system and parameters, and two 128Mbit Wave ROM chips. The part number and mask ID of the wave ROMs are different from those used by the SD-80 (either in the service manual or my particular module), suggesting they may contain different data.</p>
-<p>This is a major let down, sort of speak. The hardware is almost as capable as the XV-2020 (which has a larger CPU RAM and flash memory chip, 16Mbit and 32Mbit respectively). The XP7 is even capable of using 40 types of classical JV/XP insertion effects (MFX), which is not used at all by the SD-20. Maybe the reduced system resources prevented Roland to squeeze the XV-level editability inside.</p>
-<p>The XP7 chip runs much hotter compared to the XV chip in the SD-80. It’s almost too hot to touch when the synthesizer load is high. The XP7 chip in the SD-20 is clock much higher than any previous XP chips (33.868 MHz vs 24.576 MHz) to achieve the 44.1 kHz digital output, which is probably the cause of the excessive heat. For a more detailed technical assessment of the chip (and other Roland PCM synth chips), see <a href="https://chrisoft.org/blog/post/2020-11-20.html#tocanch16">my second post on SD-80</a>.</p>
-<p>There are 4 unpopulated switch headers on the board. Two are DPDT switches (SW4 and SW2), two seem to be buttons (SW3 and SW5). SW4 and SW5 seem to be electrically connected to the peripherals of the USB controller, SW2 and SW3 seem to be connected to the CPU. One side of SW4 seems to short the USB power. SW2 resets the unit. SW3 puts the unit into an inoperable state (USB indicator turns off, SPIDF output shuts down, does not respond to any key press / MIDI input). SW2 is weird. One side of the upper pole shorts the power to ground. The same side of the lower pole puts the unit into another inoperable state (just like frozen in place). The other side doesn’t do anything consistent. Sometimes the upper pole acts like a perpetual sustain pedal if engaged (no notes are released even after letting the connection go). All of these switches behave the same in test mode and doesn’t seem to affect boot mode selection.</p>

+XV-2020. This is likely the final iteration of the codename XP. The CPU
+is a SH7016, same as SC-8850 and SC-D70. Other major chips include two
+4Mbit EDO DRAM chips (one for CPU and one for XP7), a 16Mbit flash
+memory for system and parameters, and two 128Mbit Wave ROM chips. The
+part number and mask ID of the wave ROMs are different from those used
+by the SD-80 (either in the service manual or my particular module),
+suggesting they may contain different data.</p>
+<p>This is a major let down, sort of speak. The hardware is almost as
+capable as the XV-2020 (which has a larger CPU RAM and flash memory
+chip, 16Mbit and 32Mbit respectively). The XP7 is even capable of using
+40 types of classical JV/XP insertion effects (MFX), which is not used
+at all by the SD-20. Maybe the reduced system resources prevented Roland
+to squeeze the XV-level editability inside.</p>
+<p>The XP7 chip runs much hotter compared to the XV chip in the SD-80.
+It’s almost too hot to touch when the synthesizer load is high. The XP7
+chip in the SD-20 is clock much higher than any previous XP chips
+(33.868 MHz vs 24.576 MHz) to achieve the 44.1 kHz digital output, which
+is probably the cause of the excessive heat. For a more detailed
+technical assessment of the chip (and other Roland PCM synth chips), see
+<a href="https://chrisoft.org/blog/post/2020-11-20.html#tocanch16">my
+second post on SD-80</a>.</p>
+<p>There are 4 unpopulated switch headers on the board. Two are DPDT
+switches (SW4 and SW2), two seem to be buttons (SW3 and SW5). SW4 and
+SW5 seem to be electrically connected to the peripherals of the USB
+controller, SW2 and SW3 seem to be connected to the CPU. One side of SW4
+seems to short the USB power. SW2 resets the unit. SW3 puts the unit
+into an inoperable state (USB indicator turns off, SPIDF output shuts
+down, does not respond to any key press / MIDI input). SW2 is weird. One
+side of the upper pole shorts the power to ground. The same side of the
+lower pole puts the unit into another inoperable state (just like frozen
+in place). The other side doesn’t do anything consistent. Sometimes the
+upper pole acts like a perpetual sustain pedal if engaged (no notes are
+released even after letting the connection go). All of these switches
+behave the same in test mode and doesn’t seem to affect boot mode
+selection.</p>

The lack of advanced editing of any sort removes all possibility to explore custom sound design with the module. It’s a cheaply built unit that Roland asked for too much. Even for a Touhou music fanatic today, there are much cheaper ways to get access to the most sought-after instruments.</p>

+<p>R-BUS (also called RMDB2 / RMDB II on older products) is an obsolete
+proprietary interconnect format that carries bidirectional MIDI and
+digital audio data created by Roland. It was used on Roland products
+released from the late 90s to early 2000s.</p>
+<p>There was a physically incompatible and much rarer predecessor of
+R-BUS called RMDB (Roland Multipurpose Digital Bus). RMDB is not the
+subject of this article.</p>
+<p>Much of the information here is gathered from schematics inside
+service manuals for various Roland products, mainly the XV-5080 and
+VS-2400. These can be easily found with a search through the
+interwebz.</p>
+<p>This article assumes minimal electronics knowledge from the reader.
+As a matter of fact, the author is also a layperson in this space.
+Report of any issues in the article would be appreciated.</p>

+<h2 id="tocanch4" class="tvis">Electrical
+characteristics of the interface</h2>
+<h3 id="tocanch5" class="tvis">Power</h3>
+<p>The +5V supply is derived straight from the +5V rail that goes into
+the main board, with polarity protection (both in the XV-5080 and
+VS-2400) provided with a Schottky diode, and sometimes a current
+protected with a thermistor (not present in the XV-5080).</p>
+<p>The +5V pin measured 5.28V to ground on my XV-5080.</p>
+<h3 id="tocanch6" class="tvis">Digital Audio</h3>
+<p>The format of digital audio portion of R-BUS resembles <a href="https://en.wikipedia.org/wiki/I%C2%B2S">I²S</a>, but with a few
+key differences:</p>
+<ul>
+<li>There’s no bit clock.</li>
+<li>Sample data are transmitted as if they are 32-bit, despite only the
+first 24-bit is being used.</li>
+<li>Logic level on the data line is inverted.</li>
+</ul>
+<p>To give a standalone description of the R-BUS digital audio
+protocol:</p>
+<ul>
+<li>The frame sync (word clock) signal runs at the same frequency as the
+sampling rate.</li>
+<li>When frame sync is low, left channel of each channel pair is being
+transmitted, otherwise right channel is being transmitted.</li>
+<li>Each half cycle of the frame sync clock is divided into 32 periods,
+during each of which a bit of sample data is sent on every serial data
+line.</li>
+<li>Sample data are sent most significant bit (MSB) first. Each sample
+is 24-bit long, leaving 8 bits unused at the end of each half cycle of
+frame sync.</li>
+<li>Logic low on the data line means the bit being sent is 1, and high
+means it’s a 0.</li>
+</ul>
+<p>If you’d like a timing diagram of all this, please look up the
+datasheet of TC9271 made by Toshiba (used in the XV-5080 as its S/PDIF
+encoder chip). Figure 1b is a good representation of the relationship
+between frame sync (LRCK in the datasheet) and audio data. The LRS=H
+case in figure 3a shows how the frame sync signal sent over R-BUS should
+be interpreted.</p>
+<p>There are 4 serial data lines in each direction, giving the 8
+channels in total for each direction. Each direction has its own frame
+sync signal, which is shared among all data lines in that direction.</p>
+<h3 id="tocanch7" class="tvis">MIDI</h3>
+<p>What is sent over the MIDI wires in the R-BUS cable has not been
+confirmed by me.</p>
+<p>The MIDI interface is used differently on different Roland
+products:</p>
+<ul>
+<li>XV-5080 seem to ignore everything on the R-BUS MIDI interface,
+despite having all the facilities to handle it. Roland disclosed this in
+RPC-1’s user manual (see the section on XV-5080). I have not tested this
+claim.</li>
+<li>MV-8000 series with MV8-OP1 installed can use the R-BUS MIDI output
+as a separate MIDI port. Data going into the R-BUS MIDI port will be
+mixed with the built-in MIDI input.</li>
+<li>VM-3100Pro can pass through the MIDI data to its built-in MIDI
+ports, and can control the host sequencer if connected to a
+computer.</li>
+<li>V-Studio products can receive MIDI clock over R-BUS.</li>
+<li>Any aspects / products not mentioned here are unknown to me.</li>
+</ul>
+<p>Roland calls the signals that go in to / out of these pins “IPC” or
+“PC”. <a id="n9" href="#note9" class="note">[9]</a></p>
+<p>Inside both the VS-2400 and the XV-5080, the signal is generated /
+goes into a dedicated microcontroller (a M3888 1M2), specifically, a
+pair of its UART ports. An inverter is between the R-BUS connector and
+the MCU in each direction of the signal.</p>
+<p>Roland claims in VS-2480’s manual that R-BUS carries 8 channels of
+bidirectional digital audio (which are already fully accounted for in
+the previous section), plus MIDI, MMC (MIDI Machine Control) and MTC
+(MIDI Timecode).</p>
+<p>The factual portion of this section ends here. Everything below is my
+guesswork. Since MMC commands and MTC are both usually just sent as
+normal MIDI messages, it’s a reasonable assumption that, the only thing
+that is transmitted over these wires is MIDI, which is also why I named
+them MIDI TX/RX in my pin usage chart.</p>
+<p>Since MIDI is pretty much just UART with a bit of isolation, I would
+venture a guess that the signal sent / expected on these two pins is
+just inverted MIDI UART signal.</p>
+<p>It would be pretty trivial to build some experimental circuitry to
+test my theory. Maybe I’ll do it one day. However this may end up with
+nothing – as the XV-5080 will probably just ignore the MIDI data going
+through R-BUS.</p>

+half broken (headphone amp on analog output 1 fried due to my stupidity,
+see my <a href="https://chrisoft.org/blog/post/2020-11-20.html#tocanch2">second
+SD-80 post</a> for how it happened) and I only ever record it through
+its digital outputs anyway, I believe I can drastically reduce the
+footprint of it by taking out all the analog outputs and removing the
+now unused ±15V rail, making the device USB bus powered at the same
+time. There was also plans to add a second digital output to the modded
+SD-80, however the plan was never finalized, let alone implemented
+because of my lack of proper electronics knowledge and soldering skills.
+The idea was therefore shelved.</p>
+<p>Meanwhile in early 2022, I acquired a Roland XV-5080 (which I still
+have a long overdue review to write). I was also only recording that
+thing digitally and sometimes felt that wasting the other 3 stereo
+outputs is a shame. I did a bit of research and apparently the R-BUS
+port on its back outputs all 4 stereo outputs of the synth. Later I
+found out there was the DIF-AT and DIF-AT24 that can convert R-BUS to
+ADAT which is still fairly common on modern audio interfaces. However
+for a small box that doesn’t really do much, asking price for the DIF-AT
+is absolutely crazy – every single listing I saw was ~$200. And the
+DIF-AT24, which supports 24-bit ADAT output (in contrast to DIF-AT’s
+20-bit output), is pretty much unobtainium. So I decided to live with
+recording through its S/PDIF output for the time being.</p>
+<p>In September 2023, by pure coincidence, I found a listing on ebay of
+a chip described as “ADAT optical encoder/generator”, which was the <a href="https://www.coolaudio.com/docs/COOLAUDIO_V1401_DATASHEET.pdf">coolaudio
+V1401</a> that later would become the heart of my design. After reading
+its datasheet I decided it would pretty much make my SD-80 digital mod
+trivial, with the added benefit of carrying both stereo output channels
+on a single port. So I opened up the service manual for SD-80 and
+started to study which pin each signal should go to. However I quickly
+realized that performing the mod would require soldering around the XV
+chip inside the SD-80, which is still a thing that I’m not really
+willing to do; and that I could easily test out my theory on XV-5080’s
+R-BUS port because the digital audio output pins on XV-5080’s R-BUS port
+is pretty much directly connected to the XV chip through an
+inverter.</p>
+<p>To summerize … I came up with a solution for a problem that I made up
+for myself.</p>
+<h2 id="tocanch1" class="tvis">Background check on the chip</h2>
+<p>The seller of the chip claims the chip is an equivalent of the AL1401
+from Alesis, which sounds quite interesting as Alesis is actually the
+company behind ADAT (<u>Alesis</u> Digital Audio Tape, as for why it’s a
+tape not a optical interface… that’s a story for another time).
+Suspicion that this chip is a Chinese clone arose. So I did a bit of
+background on the company … <a id="n1" href="#note1" class="note">[1]</a></p>
+<p>Turns out, of course it is. While its roots can be traced to the US
+in the 90s, design team of coolaudio is now located in China
+<a id="n2" href="#note2" class="note">[2]</a>. Better still, it’s a brand
+of Music Tribe, which is Uli Behringer’s company. Yes it’s the same
+person who founded Behringer which is best known as the legal (/s) clone
+audio equipment manufacturer. <del>No wonder why coolaudio’s product
+portfolio is all clone chips.</del></p>
+<p>Well, the original AL1401 is pretty much impossible to find nowadays,
+so I really have no choice don’t I?</p>
+<h2 id="tocanch2" class="tvis">Ill-fated commencement</h2>
+<p>I ordered the V1401 chips before my end-of-year vacation travel. When
+I returned from my vacation, I found these in my mail box:</p>
+<div style="text-align:center;">
+<a href="//filestorage.chrisoft.org/blog/img/rbdt-pk.jpg"><img style="width: 50%;" src="//filestorage.chrisoft.org/blog/img/ssbsthumb_1024x1024_rbdt-pk.jpg"></a><br>Suspicious packets
+</div>
+<p>which may look suspicious to law enforcement… but they are actually
+just chips. Not the edible kind.</p>
+<p>My prior experience with electronics is only limited to reading
+schematics and disassembling (and destroying in the process) hundreds of
+home appliances. So I guess I have seen hundreds of printed circuit
+boards but I haven’t ever made or designed one of my own. I did take a
+class during my undergrad that involved programming FPGAs, which did
+have a “drawing schematics on a computer” component to it, but that
+didn’t have anything to do with PCB design.</p>
+<p>Since I do not have any prior experience working with EDA software, I
+toyed with an Chinese online EDA toolkit that literally has “easy” in
+its name (EasyEDA) and drew a tentative schematic for the supporting
+components. Apparently it wasn’t that different from what I used when I
+was taking the FPGA class, but at this stage I still haven’t confirmed
+many aspects of the characteristics of R-BUS yet. As a result there were
+a multitude of issues with this schematic. However it did help me come
+up with a list of components (“bill of materials” in more professional
+terms) needed for the project. I ordered these together with some
+prototyping supplies online, hoping to actually build a prototype once
+they have arrived.</p>
+<div style="text-align:center;">
+<a href="//filestorage.chrisoft.org/blog/img/rbdt-es.png"><img style="width: 50%;" src="//filestorage.chrisoft.org/blog/img/ssbsthumb_1024x1024_rbdt-es.png"></a> <br>The error-riddled
+schematic
+</div>
+<p>I need an audio interface with ADAT inputs because none of the bunch
+I already own has one. Since the Scarlett 18i8 3rd gen was on sale for
+$360 at the time, I decided to get one.</p>
+<p>When I was reviewing the datasheet for the components I ordered
+<a id="n3" href="#note3" class="note">[3]</a>, I
+found out that I’ve ordered the wrong optical transmitter. The part I
+ordered was TOTX1353 which only supports up to 500 kb/s data rate … less
+than 1/20 required by an ADAT data stream. However for some stupid
+reason that I couldn’t recall, I decided to try prototyping with it
+anyway.</p>
+<p>I soldered one of the V1401 chips to the SOIC carrier board. As this
+time I used plenty of proper, good quality flux as suggested the MacBook
+repair guy Louis Rossmann <a id="n4" href="#note4" class="note">[4]</a>, the result didn’t look
+nearly as bad as my previous SMD soldering attempts and I was quite
+happy with it.</p>
+<p>On the following day I started showing mild symptoms of a common
+cold. Later that night a fever kicked in. The next day I decided to use
+an expired Cornweed <a id="n5" href="#note5" class="note">[5]</a> test kit on myself and found out Cornweed was
+growing inside me (hence the name of this subsection).</p>
+<p>I got a week off from my workplace to get rid of the Cornweed. Since
+I already felt much better after one day, I started breadboarding. It
+was finished pretty quickly. But soon after that I found out there was
+more than one thing wrong with the optical transmitter module I chose –
+the module doesn’t have a drive circuitry built in and it pretty much
+just a bare LED. There is no way in hell that it can be directly driven
+from the output of a 74LS04. The LED in the transmitter only barely
+lights up when the output is active. At this point I finally realized
+that I can’t use this out of spec piece of crap in the final design
+anyway, so I placed order for a few transmitters that are more fit for
+the job.</p>

+<p>When I was trying to wire in the DB-25 terminal block, I found out
+that I don’t have the proper flathead driver for the screws. So I had to
+get one of those as well.</p>
+<p>Once I really had all the items I need, I started putting things
+together. The process was fairly easy but the audio interface didn’t see
+the ADAT signal on the first attempt. I double checked all the
+breadboard connections and inputs to the chip, which appeared to be all
+correct. Feeling tired, I removed the prototype from my desk to work on
+it the following day, unplugging all the cables in the process.</p>
+<p>To my utter surprise, the thing straight up worked when I plugged it
+in on the next day. It turns out that the port on the new transmitter is
+very tight and takes quite a bit of force to insert the plug all the way
+in.</p>

+</div>
+<h2 id="tocanch3" class="tvis">Designing the board</h2>
+<p>I decided to switch to KiCad soon after I started the actual
+prototyping process, probably due to my bias towards free software.</p>
+<p>Drawing the schematics wasn’t hard. Although I did have to read the
+manuals to find out how buses work in KiCad.</p>
+<p>There is no symbol for the V1401 chip in KiCad’s default library, and
+no symbol or footprint for the optical transmitter. I had to learn how
+to draw these and make them myself. Fortunately the process is pretty
+straightforward and the datasheet has everything I need.</p>
+<p>I spent some additional time studying the digital / analog audio
+output section of XV-5080 to find out the format of digital audio data
+coming out of the XV chip. Once that was done I was able finalize the
+schematic. I started learning routing in KiCad soon after that. However
+that effort was put on hold as soon as I realized I should really
+validate the schematic on breadboard first.</p>
+<p>Once I got the breadboard version working, I started working on
+routing the board again. It started pretty difficult, as certain
+crossings couldn’t really be avoided. However once I started making
+liberal use of vias the problems got solved pretty quickly. I then
+recalled seeing large ground plane on most circuit boards that I’ve laid
+my eyes on and found out those can be made in KiCad with “zones”.
+However for some (not completely insane, but still pretty stupid) reason
+I thought adding too much copper could add to the manufacturing cost, so
+I was … quite stingy with the zones. Maybe I should fix it in the next
+revision.</p>
+<p>Finally I added some personal markings on the board. I decided to try
+the svg import feature of KiCad and drew something in Inkscape within a
+minute. Once placed on the board it actually looked pretty nice. Yes it
+is a Touhou reference, now stop asking why.</p>

+<p>The design was now ready and I started looking for PCB manufacturers.
+I settled between a few Chinese manufacturing providers for price
+considerations. My final manufacturer of choice was JLCPCB, mostly
+because they have the best reviews in China. I submitted the files and
+waited anxiously for the boards to arrive.</p>
+<p>The boards arrived astonishingly fast. In just 5 days it went through
+the entire production sequence as well as the Pacific Ocean, and arrived
+at my door steps. I test fit all the components, which all fit just
+fine. Next was the final assembly which also went pretty smoothly. After
+a quick test the board was found to work perfectly. I was actually
+shocked that the very first PCB designed by me worked first try. To be
+fair the board itself is pretty simple. It was figuring out the R-BUS
+protocol that made the project slightly tricky. Actually I’m pretty
+surprised to find out that nobody has done the work already given the
+service manual of XV-5080 has been floating around on the Internet for
+many years now. Anyway, this has been a fantastic starter electronics
+project for me and the process has been quite enjoyable.</p>

+<h2 id="tocanch7" class="tvis">Potential future work</h2>
+<p><del>First of all I need to fix the stingy ground plane.</del></p>
+<p>V1401’s datasheet isn’t very clear on whether it can generate a
+24-bit ADAT stream. Recordings made with the Scarlett 18i8 seem to have
+the full 24-bit resolution, but that could be due to interpolation done
+by the audio interface or operating system. Testing this requires an
+oscilloscope which I currently don’t have.</p>
+<p>It is highly feasible to implement an ADAT encoder / decoder in
+software on cheap microcontrollers like the rp2040. The ADAT protocol is
+documented <a href="https://ackspace.nl/wiki/ADAT_project">here</a> and
+seems fairly straightforward to implement. This also has the added
+benefit of making sure that 24-bit ADAT is really supported. However
+this will also more than likely require an oscilloscope for debugging.
+I’ll also have to learn rp2040’s PIO programming and theories on PLL
+operation, both from scratch.</p>
+<p>Exposing the MIDI interface on R-BUS also seems possible. However it
+seems that XV-5080 doesn’t make use of the MIDI interface on R-BUS
+<a id="n6" href="#note6" class="note">[6]</a>.</p>
+<p><del>Maybe I’ll add more Touhou references to the silkscreen, who
+knows.</del></p>
+<h2 id="tocanch8" class="tvis">I want one! What should I do?</h2>
+<p>First of all I’d suggest giving the <a href="ddd">manual</a> a read
+to make sure this board really does what you want.</p>
+<p>If you have made up your mind to get a board, I have some bad news
+for you. Unfortunately right now there’s no straightforward way obtain
+this board. Mainly because I have never sold anything online. Also this
+board is bound to be a very niche product, and possibly can’t even
+recover the development costs if I decided to sell them. Those are the
+reasons why I currently have no plans to sell the board.</p>
+<p>So right now your options are:</p>
+<ul>
+<li>Build the board yourself. The design is fully open source and build
+instruction is included in the manual. If you are comfortable with
+electronics DIY projects, this is probably your best bet.</li>
+<li>Let me know you want one! Right now I still have a few
+pre-production boards lying around. As long as you’re willing to cover
+the terrible USPS shipping rates I’m willing to assemble a board and
+send it your way. Of course you’re welcome to pay a little bit more… but
+any excess for now will be treated as donations (a “pay what you think
+it’s worth” model) – as I don’t have pricing fixed yet. Also if enough
+people have expressed interest in the board I might actually start
+selling them…</li>
+</ul>
+<h2 id="tocanch9" class="tvis">You’re an idiot and
+your design is trash!</h2>
+<p>First of all, thank you. I am indeed a massive idiot.</p>
+<p>If you have suggestions on how this board could be improved, please
+consider sending them to me. As a beginner in electronics design I can
+definitely use any piece of advice coming from pretty much anyone in
+this field. Any constructive suggestion will be greatly appreciated.</p>
+<p>Of course other types of contributions will also be appreciated. For
+example this board currently lacks any kind of enclosure as I have zero
+idea how to create 3D models for real-life object manufacturing. Help in
+this space is desperately needed.</p>

+<!-- l. 57 --><p class="noindent">If you are reading this, chances are you have become an unfortunate test subject of the RBUS-ADAT conversion
+board (or have the nerves to think about becoming one). Well, here is (almost) everything you will want to know
+about the board. If you want to learn about some less useful information about this thing, consider checking out
+the devlog, which can be found by following the link to the project homepage listed under “Useful
+links”.
+</p><!-- l. 64 --><p class="indent">   As this manual is written as if it’s a blog post, which is prone to being very rambly, I’ll try to keep the rambling
+low, at least make an attempt to do so.

+<!-- l. 105 --><p class="noindent">There’s no enclosure for this board. As a result there would be exposed conductors on both sides of the board.
+You’re advised to take measures to prevent them from shorting out. You may try any combination of the
+following:

+     <ul class="itemize1">
+     <li class="itemize">
+     <!-- l. 110 --><p class="noindent">Placing the board on an non-conductive surface.

+     <!-- l. 111 --><p class="noindent">There are two M2 mounting holes in the board. Using two M2 screws and nuts, install a plastic sheet
+     (or cardboard even) under and / or over the board.
+

+<!-- l. 124 --><p class="noindent">RBUS-ADAT is designed for use with the Roland XV-5080. It converts the 8 digital outputs exposed by XV-5080’s
+R-BUS port to a standard ADAT lightpipe stream which can be recorded with any audio interface with an ADAT
+input.
+</p><!-- l. 128 --><p class="indent">   The ADAT output from this converter is 20-bit and has the same sampling rate as the input supplied from the
+R-BUS port.
+</p><!-- l. 131 --><p class="indent">   This converter <span class="ec-qplb-x-x-109">cannot</span>:

+     <!-- l. 138 --><p class="noindent">Expose the MIDI interface on the R-BUS port.</p></li></ul>
+<!-- l. 141 --><p class="indent">   The converter is designed and tested with the XV-5080. In addition, the only audio interface that
+has been verified to work is Focusrite Scarlett 18i8 3rd gen. I don’t have the resources to test other
+devices.
+</p><!-- l. 145 --><p class="indent">   The converter has not been tested against VM- or VS- devices that feature RMDB 2 / R-BUS ports
+or MV-8<span class="cmsy-10x-x-109">××× </span>fitted with the MV8-OP1 expansion but may still work as a unidirectional converter
+as intended. If you decide to try this converter with these devices, reporting the results would be
