IIRC, certain devices use standard midi/usb messages, but they hide
the fact that they use the same message format as class compliant ones
to avoid triggering a bug in (very) old windows versions.
you can try to guess how your device works and if possible add a quirk
to the umidi(4) driver, as follows:
- figure out which usb endpoints appear to work, run:
cat -u /dev/ugen0.N | hexdump -e '1/1 "%02x\n"'
and play something on the keyboard until it prints 4-byte messages,
try it for N = 1..15
- add the device to /usr/src/sys/dev/usb/usbdevs, run "make" in the
same directory to update .h files (keep strings short as they are
for other devices).
- add the corresponding "fixed endpoint" quirk in umidi_quirks.c
probably one similar to the "UM-1" one.
Drop me a e-mail if it works and/or you have any questions.
Good luck
