give me as many details about problems as you can. i don't have much
time for testing. also make sure the files have just one tempo event in
the beginning of the file (check with midi event lister) if youtry a
file and there are problems, tell me exactly what they are (shift is
wrong, note timing screwed up, notes overlapping etc etc) and send both
the original file and the modified one. if you see a specific problem,
tell me the time (either clock time or midi ticks to the messed up part
if there is one) this would make my testing much easier.
