It's been a while since I played with the RMX driver, but I seem to
recall that this is the situation:
1. Audio: Appears as a class-compliant USB 1.0 Audio device. Done.
2. HID: Appears as a class-compliant USB HID device. I never dug
in to what the "HID" thing was doing. On some systems, X Windows
would consider it to be a mouse... which was a big PITA. It
would send events whenever a MIDI event would happen, but I didn't
mess with decoding them.
3. MIDI: To get the RMX to appear to Linux as a MIDI device, it
required patching the kernel with the "RMX driver." I never dug
in to see how the MIDI driver was implemented.
If the RMX MIDI driver could be added to the main-line kernel, that
would make many people very happy. I imagine that there's a couple
reasons why it isn't already there: (a) nobody with the kernel hacking
skilz AND an RMX has sponsored it, and (b) the code might not be up to
the quality required for inclusion in the Linux kernel.
