Larry,
I ask most of mine on Alsa-Dev, and generally get pretty fast
answers. I'm about to start a MIDI problems thread (big problems
unfortunately...) and have to decide where to do it, so your email is
timely.
Unfortunately, I don't still have the email, but I think I read something
from Frank Barknecht to the effect that this list really should have been
called linux-audio/midi-user.
if you promise not to use the MIDI wisdom you harvest off this list for
anything other than producing audio of some kind, it's probably ok here :-P
