I realized what I provided previously as info about the received packets for
the Akai MPD16 was misleading, as it was, unbeknownst to me, contaminated
by a lot of stuff coming in from my Yamaha Motif (apparently a chatty little
beastie.) Heres some better dmesg output with the Yamaha turned off:
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 21 fe ]
received packet: [ 23 90 24 7f 23 90 24 00 ] <--- this is where I hit one of
the pads.
received packet: [ 21 fe ]
received packet: [ 21 fe ]
Trying to chase down the udev stuff, I find snd_rawmidi_new() is where
I think the /sys/class/sound/midiC1D0 things that udev is using are coming
from, but this appears to be called only by snd_usbmidi_midi(), which sppears
to be called . . . well, nowhere.

Hmmm, maybe there is a preprocessor macro making life difficult for me in there
somewhere. Would it be better to ask on the kernel mailing list about this
udev stuff?
Thanks,
