At the risk of trying to troubleshoot a system I'm completely unfamiliar
with, I'm not sure that that's a correct diagnosis. The only way a MIDI note
number could be outside of the range [0, 127] is if the high bit of its byte
was set. The MIDI spec says that if the high bit of a byte--any byte--is
set, then it's a Status byte, not a data byte. [See pages 4-5 of the MIDI
spec] So in other words, could it be that "some software programs" are
sending Status bytes that the 650 isn't expecting, rather than "'illegal'
MIDI notes"?
