No.  I rewrote the handling of the various USB MIDI protocols, but my
SC-8820 that uses the same protocol as your keyboard still works fine.


Is snd-usb-audio loaded?

Is usb-midi _not_ loaded?

Does the device appear in /proc/asound/cards and in the output of
"amidi -l" and "arecordmidi -l"?

Is there some output for keys and/or controllers when running
"amidi -d -p portname"?
