Its been a while since the topic of MIDI bank selection was discussed,
so I'm frustratingly in the dark again about it.  From what I read a
bank/program change is sent as such:
Bank MSB (CC #0)
Bank LSB (CC #32)
Program change

So in that case if 1 was sent for MSB and 0 was sent for LSB it would
mean bank #128.  If only a MSB is sent though, as in the cited example
case, I'm suspecting that should be interpreted instead as an LSB
value?  Not sure exactly what standard defines such behavior though.
Does this sound like what the issue is related to?
