It's probably just me being hyperallergic, but it also could be Google doing something really unfair to their users.</p> +<h1 id="software-subscription-model-sucks">Software Subscription Model Sucks</h1> +<p>Reading through Roland Cloud's product page triggers me everytime: I sincerely cannot figure out why they make it a subscription service rather than a one-time purchase (with a fee for each upgrade).</p> +<p>Usually people subscribe for:</p> +<ul> +<li>Publication or media services, e.g. television, newspapers and magazines. These services provide frequently updated information to the subscriber.</li> +<li>Physically consumable material, such as dairy product.</li> +</ul> +<p>Roland Cloud falls into neither of these two categories. It's not updated as frequent, and it's certainly not physically consumable. The most triggering detail is that if you end your subscription, you will not be able to use any of the products you previously owned, which is ridiculous because you can always keep older issues of a newspaper even you unsubscribed from it.</p> +<p>Supporters of the subscription model may reject me saying 'if you can get access to everything when you join and keep it after unsubscribing, you are essentially purchasing it with ultra-low price', which brings up my next point: Roland Cloud's subscription model is flawed from the beginning:</p> +<ul> +<li>Get everything on subscribe: this differs from traditional subscription a lot, which seems a great bounty to the customer. But it causes problems such as ...</li> +<li>Lose everything on unsubscribe: this is <em>very</em> unfair to the subscriber and makes short-term subscription worth almost nothing. For example if I just want Sound Canvas VA really badly, I would imagine subscribing shortly before its release and unsubscribe after I'm eligible for keeping the product permanently. But this is simply not possible.</li> +<li>Weird pricing. To be honest the current pricing is pretty fair for long-term subscribers. But if Roland somehow decided to fix the 'lose everything on unsubscribe' problem (which is very unlikely to happen), the pricing would become super complex: they probably do not want people to keep a virtual TB-303 for just $19.99.</li> +<li>Potentially unsustainable. Every good thing must come to an end. The most attractive products in Roland Cloud is the software models of Roland's synthesizers from its golden years. But Roland will run out of models to recreate one day. What would Roland do by then? Release everything as a one-time purchase so that every long-term subscriber feels ripped off?</li> +</ul> +<p>I'm an absolute supporter of Roland releasing authentic-sounding digitialized version of their legendary synthesizer models. But their subscription model pisses me off so hard. I know it's not a big deal for a professional producer. However this is a real deal-breaker for amateurs such as me.</p> +<p>Unfortunately there's no real competitors out there when things come to reproducing their own synthesizers. Also a little bit off-topic: the music producing industry deserves more high quality free (as in freedom) software.</p> +<p>Now let's move on and talk about Office 365 by Microsoft and Creative Cloud from Adobe. They bundles software with value-add services such as e-mail service and (optinal) creativity material. IMHO these products they are trying to turn into a service resemble a tool, such as a screwdriver, rather than an apartment that people actually go for renting instead of purchasing.</p> +<p>Paying a monthly fee for a screwdriver makes absolutely no sense. That said, I would stick with my plain old screwdriver, rather than that shiny gold-plated screwdriver with 10 heads which I will lose whenever I stop paying them. <strong>Green is my pepper.</strong></p> +<p>The purpose of this entire rant is to remind the reader of just how many ways proprietary software vendors could come up with to screw their users up. What they care the most has always been money and this will simply not change any time soon.

Even though I'm a newcomer to the STUDIO Canvas owners community, veterans may still find something interesting here.</p> +<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> +<table> +<tbody><tr> +<td> +<div style="text-align:center;max-width:98%;"> +<a href="//filestorage.chrisoft.org/blog/img/SD-80_top.jpg"><img style="width: 50%;" src="//filestorage.chrisoft.org/blog/img/ssbsthumb_1536x1536_SD-80_top.jpg"></a> <br>Top cover +</div> +</td> +<td> +<div style="text-align:center;max-width:98%;"> +<a href="//filestorage.chrisoft.org/blog/img/SD-80_label.jpg"><img style="width: 50%;" src="//filestorage.chrisoft.org/blog/img/ssbsthumb_1536x1536_SD-80_label.jpg"></a> <br>Label with S/N removed.

But those kind of things are scarce today. The cloest 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 availble: 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> +<h3 id="tocanch3" class="tvis">Settings things up in Linux</h3> +<p>If you are absolutely insane and using Gentoo Linux just like me, make sure you've already got working audio and have the following kernel configuration items enabled:</p> +<pre><code>Device Drivers ---> + <*> Sound card support + <*> Advanced Linux Sound Architecture ---> + [*] USB sound devices + <*> USB Audio/MIDI driver</code></pre> +<p>Both SD-80 and Scarlett Solo should then just work out of box (if you are using pulseaudio <a id="n1" href="#note1" class="note">[1]</a>).</p> +<p>At first I thought only the 'generic' USB mode of SD-80 is supported by this kernel module, however it turns out the 'vendor' USB mode works just fine as well. It also suffers a lot less stuttering.</p> +<p>The USB vendor ID and product ID is 0582:0029. Changing the USB mode to generic makes it 0582:002a.</p> +<p>In order to monitor the input, load the loopback module first:</p> +<pre><code>pactl load-module module-loopback latency_msec=1</code></pre> +<p>(<code>latency_msec</code> means exactly what the name suggests)</p> +<p>then move it to the audio input of the audio interface:</p> +<pre><code>pacmd move-source-output 7 alsa_input.usb-Focusrite_Scarlett_Solo_USB-00.analog-stereo</code></pre> +<p>where 7 is the index of the loopback followed by the name of the input of your audio interface. Usually you can use tab completion, however if you are still unsure, you may also use a GUI utility such as <code>pavucontrol</code>.</p> +<p>I haven't tried JACK yet. But using QjackCtl should make everything a breeze.</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. As the device works with a generic driver on Linux even when the USB mode is set to 'vendor', it will probably work on Windows without the Roland driver too. Although I'd rather install the official driver for Windows 8/8.1 because there is one.</p> +<p>The tweak is simple. Open up <code>RDIF1023.INF</code> in a text editor, copy everything under section <code>[Roland.NTamd64.6.2]</code> to section <code>[Roland.NTamd64.7]</code> and you are good to go. Driver signature enforcement has to be disabled as stated in the quick start manual.</p> +<p>Settings up monitoring is as simple as clicking on a checkbox in the control panel or a button in your DAW. You just don't see one use the command prompt for this purpose on Windows.</p> +<h2 id="tocanch5" class="tvis">What does it sound like?</h2> +<p>Well, it sounds super 'ZUNish', if you've ever listened to Touhou music.

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> +<h3 id="tocanch9" class="tvis">Recording</h3> +<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="tocanch10" 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="n6" href="#note6" class="note">[6]</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="n7" href="#note7" class="note">[7]</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="n8" href="#note8" class="note">[8]</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.</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> +<p>I'm not going to scatter the post with even more pictures, so please follow the links for selected screenshots of the editor:</p> +<p><a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_a.png">main screen</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_b.png">'part survey'</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_c.png">layers</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_e.png">amp EG</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_f.png">LFO</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_h.png">layers mapping</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_i.png">modulation matrix</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_k.png">patch options</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_l.png">'part all'</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_m.png">MFX editing</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_r.png">Rhythm layers editor</a> / <a href="//filestorage.chrisoft.org/blog/img/SD-80_editor_u.png">Rhythm amp EG</a></p> +<h3 id="tocanch11" class="tvis">Impact on the workflow</h3> +<p>First of all I've to record and thus, deal with latency, noise and clipping. It's pretty annoying as already mentioned above.</p> +<p>Also the SD-80 doesn't integrate very well with any DAW. There's no way your settings of this hardware synth get saved automatically with your project like a virtual synth. Also forget about automation and all sort of things. You have to use MIDI events and system exclusive messages (especially tuning some obsecure parameters) for this purpose, and DAW software doesn't have great support for system exclusive messages in general.</p> +<h2 id="tocanch12" 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="n9" href="#note9" class="note">[9]</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' (persumably 'Mellow Grand Piano' in XG specification), which is not listed in the manual. It actually has ~480 normal patches, ~50 sfx patches, 2 sfx kits and 9 drum kits <a id="n10" href="#note10" class="note">[10]</a>. It's quite irony to find out that they have more patches for their competitor's standard than their own legacy standard.</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="n11" href="#note11" class="note">[11]</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're 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> +<h2 id="tocanch13" class="tvis">Beneath the chassis</h2> +<p>Although I cherish the module quite a lot and there are warning text on top of it (which I can't read because it's in Japanese and ... well, English), I disassembled the unit.</p> +<div style="text-align:center;max-width:90%;"> +<a href="//filestorage.chrisoft.org/blog/img/SD-80_caution.jpg"><img style="width: 50%;" src="//filestorage.chrisoft.org/blog/img/ssbsthumb_1536x1536_SD-80_caution.jpg"></a> <br>CAUTION!! 注意!!

Rated voltage for the module seems to be changable by using different pin layouts on the input side. The power supply module is made of two separate boards.

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. Maybe that's the limitation of the single chip. Also one can tell the chip also handles some weird job such as LED indicators from the circuit board schematic.</p> +<p>A very lonely chip on the right side has '6417706' on it. Turns out this is a microprocessor implementing the SuperH architecture. It's the same CPU as found in MC-909 (which makes sense as they are produced around the same time). Linux kernel has support for this processor<a id="n13" href="#note13" class="note">[13]</a>. The processor has a maximum clock speed of 133 MHz and is underclocked to 128MHz in the MC-909. It's probably underclocked even more in the SD-80. There's an unpopulated D-sub connector persumably for debugging near the CPU.</p> +<h3 id="tocanch15" class="tvis">Testing mode</h3> +<p>According to the service manuals available for other models, they all have a hidden test mode. Some also have the ability to update system firmware. Entering testing mode often involves turning the power on with a combination of keys pressed. Every model have its own way to enter testing mode and there's no obvious pattern. At that point, I was desprate to dive into it. So I simply tried all button combinations consisting of one to three buttons. The result didn't let me down. I found three combinations that make the SD-80 boot into special modes.</p> +<ul> +<li>INST + SHIFT + PART▶ = Test Mode</li> +<li>INST + PAGE◀ + PREVIEW = Program Updater</li> +<li>SYSTEM + PAGE◀ + PREVIEW = Program Updater</li> +</ul> +<p>Below is everything I found about these modes.</p> +<div class="collapse" caption="Special boot modes in the SD-80"> +<p><strong>Test Mode</strong></p> +<pre><code>00 Version Check +1.03 0022 2002/07/29</code></pre> +<p>(Preview blinks, pressing it doesn't seem to do anything)</p> +<pre><code>01 Device Check + ALL OK!!</code></pre> +<p>(I got <code>NG:XV2</code> shortly after heavily using the module for a while. MFX in test 7 produces no sound at all, system delay only has the dry sound, everything else was normal. More on this later.)</p> +<pre><code>02 MIDI Check +MID1:x MID2:x THRU:x</code></pre> +<p>(No MIDI cable for me until I'm home... Input from USB does not count.)</p> +<pre><code>03 LCD Check +PAGE:Sel / ENC: Contr</code></pre> +<p>(PAGE buttons switch among the following four patterns: none, full, chequerboard 0, reversed chequerboard. Contr=Contrast)</p> +<pre><code>04 SW/LED Check + ooooo ooooo</code></pre> +<p>(All buttons and indicators light up. Transparent buttons turns off its light, opaque buttons turns off LED above or below it, ENTER button turns off nothing. The five <code>o</code>'s on the left corresponds to the upper row, others corresponds to the lower row. Pressing a button turns its character to <code>#</code>, releasing it causes it to change to <code>.</code>.)</p> +<pre><code>05 Encoder Check + Value(0-23) = xx</code></pre> +<p>(+ Plays C3, - Plays E3, both using the piano voice. Value starts at 00. Interestingly if the encoder is turned too fast, the value on screen does not change until you stop.)</p> +<pre><code>06 Sound Check +Push button to check + Left channel + Center channel + Right channel</code></pre> +<p>(INST/EFFECTS/SYSTEM blink, pushing one makes it constantly on while others still blinking and plays the corresponding check. Plays sine wave on the selected channel(s))</p> +<pre><code>07 Effect Check +Push button to check + MFX(Delay) + System Delay + System Reverb</code></pre> +<p>(Same as test 06. The sounds used for these checks are snare, castanets and side stick respectively.)</p> +<pre><code>08 Factory Reset + Push [PREVIEW]</code></pre> +<p>(PREVIEW blinks, pressing it really resets!)</p> +<p>The SD-80 still works as a sound module in test mode -- it will play any incoming midi stream. The module is in native mode regardless of your settings. MFX doesn't seem to be working normally (likely due to it's reserved for test 07). Switching between tests resets some (if not all, depending on the test switing to) of the synthesizer's states. Switching to test 05 sets some of the instrumental parts to piano and others to a certain synth lead patch. Switching to test 06 sets sine wave and piano on all instrumental parts just like test 05. Switching to test 07 sets certain instrument parts to a drum patch, the patch 'Xtremities' could also be heard. Other parts are set to piano.</p> +<p><strong>Program Updater</strong></p> +<pre><code>Program Updater +Version: 1.03</code></pre> +<pre><code>Program Updater +Prog:12D3[12D3]1.03</code></pre> +<pre><code>Program Updater +Updt:66FB[66FB]1.00</code></pre> +<pre><code>Program Updater +Boot:5170[5170]1.01</code></pre> +<pre><code>Update by MIDI +[ENTER][SHIFT(Exit)]</code></pre> +<pre><code>Update by USB +[ENTER][SHIFT(Exit)]</code></pre> +<ul> +<li>INST = Program version (INST lights up)</li> +<li>EFFECTS = Updater version (EFFECTS lights up)</li> +<li>SYSTEM = Boot version (SYSTEM lights up)</li> +<li>SHIFT = Returns to initial screen of the updater</li> +<li>PART◀ = Update by MIDI</li> +<li>PART▶ = Update by USB</li> +</ul> +<p>MIDI and USB indicators blink on any screen with the top row saying <code>Program Updater</code>.

This combination is probably reserved for consumers.</p> +<p>Sound generation does not work in the program updater.</p> +<p>Persumably the update MIDI files are similar to earlier models: stream of system exclusive events containing firmware blobs. No program update could be found for the SD-80 on the Internet.</p> +</div> +<h3 id="tocanch16" class="tvis">Messing around sans the chassis</h3> +<p>As the two XV chips are arranged in a master-slave manner, I tried figuring out which one is acting as the master. I threw a bunch of midi files at it while measuring the temprature of the XV chips... with my fingers. Both chips turn quite toasty but IC19 is always warmer than IC27, sometimes it's even a little difficult to keep my finger stay on that chip.</p> +<p>When the action gets more intense, IC27 starts to warm up. Before I was just going to conclude that IC27 is acting as the master, I realized that I will never come into a meaningful conclusion without further reverse engineering: I have absolutely no idea how the load is distributed between the two XV's!</p> +<p>Frustrated, I entered testing mode to find out whether there's anything interesting if it's run with chassis removed. To my surprise, the device check failed with <code>NG:XV2</code> and a bunch of other errors in the following tests. I thought I was doomed, but a reboot of the module solved the problem completely and it never show any trace of abnormality that day.</p> +<p>The other day, however, the problem returned. After messing with the SD-80 editor and creating random complex patches for an hour, I randomly decided to check out the testing mode again, where I was greeted by the <code>NG:XV2</code> failure the second time. Again, a reboot solved the problem for the day. No amount of hardwork will put the SD-80 into a buggy state if it boot straight into normal mode. At this point I thought it could be a bug in the test or the device check could be quite sensitive to temprature, which is probably not a very good thing as there're ninno vent holes for airflow on the module whatsoever.</p> +<h3 id="tocanch17" class="tvis">Chart A</h3> +<div class="collapse" caption="Comparison of internal components found in selected Roland devices"> +<p><a id="n14"

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="tocanch20" 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="n15" href="#note15" class="note">[15]</a> This is a huge drawback of using a hardware synthesizer that Roland still fails to fix to this day.</p> +<h2 id="tocanch21" class="tvis">If you want to learn more ...</h2> +<ul> +<li><a href="http://www.gigadenza.co.uk/?page_id=5116&all=1">Gigadenza</a>, owns multiple sound modules, including the latest INTEGRA-7.</li> +<li><a href="https://twitter.com/Romantique_Tp">Romantique Tp</a>, a Touhou music addict that I came across on Steinberg user forum.</li> +</ul> +If you spot a mistake or have anything you wish to share on this topic, please do not hesitate to drop me a message. +</article> +</div><br><hr> + <div class="TText" id="notediv" style="font-size:80%;"><span class="TText"><a id="note1" href="#n1">[1]</a>: Pulseaudio sucks a lot less compared to the old days, it even switch automatically between built in Intel HD Audio and external USB audio device when it's plugged in / unplugged.<br></span><span class="TText"><a id="note2" href="#n2">[2]</a>: SD-90 doesn't seem to have a non-zero modulation level according to its manual.
