# Chrisoft::RBUSIF Information on R-BUS / RMDB 2 and my related projects. Projects and technical information provided on this page and all linked pages are not approved or endorsed by Roland.
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. (Excerpt from the detailed information page) For more detailed information on the R-BUS format, including electric and signaling specifications, please visit [this page](https://chrisoft.org/blog/post/2024-02-02.html). A (currently very short) list of my projects related to R-BUS:
