Ok, sorry, I accidentally sent this only to Mark; it was supposed to go
to the whole list. (Thanks, Mark, for pointing this out.)

Further notes: I realize the MidiSport is a USB device. I'm not sure
what to do about that, but my USB controller and sound card were on
different interrupts and I was still having problems. I'm not sure if
this applies to newer boards, but this is a known bug.
