(Somewhat tangentially: If you take a look at the MIDI over USB

I find that analogy a little confusing -- it implies that you might see
a stream of 4-byte USB-over-MIDI packets, which is definitely not the
case; it's a valid MIDI stream with a few additional constraints (as
mentioned in my last email) to simplify parsing.
I suppose I should have said "is similar" rather than "maps quite
closely". Anyway, reading about MIDI over USB helped me understand
what I was empirically seeing in the packets, especially why the packets
were so small (in the case of sysex). Of course now I know that it
doesn't matter so much, but it was an interesting diversion.
