Would I be right in thinking you have a Logitech mouse driver? A couple
of people have reported this problem, and managed to fix it by switching
to a different driver. I have no idea what is causing it, or how to fix
the problem, and have been unable to duplicate it on my machine.

One thing to try: insert frequent calls to __dpmi_yield() in your main
program loop, and see what happens (please let me know if that makes it
work).

Is this with Allegro 2.2? The timer problem in Allegro 2.11 would cause
exactly such timer errors, but although the v2.2 timer routines are less
accurate under Win95 than in DOS, the errors shouldn't be enough to
cause noticable errors in MIDI playback...
