Hmmm..  I haven't written any midi software, but experience tells me that
this sort of bug is often a timing problem.  Basic runs slower than the
equivalent stuff in assembler, so any delays which are *required* by the
midi device will be built into the basic code.  He might try inserting busy
waits into the code as an experiment, then if the code now works, start
eliminating the waits until the pertinent one is found.  

Otherwise, try reading up in any of the midi device documentation (long
shot, knowing synth manufacturers) or even calling the manufacturer for any
timing-related info which you ought to have been told about.

Just a suggestion....
