I've never measured MIDI timing stability in W98, but in general Pd doesn't
time MIDI I/O carefully in either NT or Linux; output gets sent at the time
teh audio is COMPUTED, not when the audio actually appears on the output.
To reduce MIDI jitter, you can reduce audio latency to the lowest amount
Pd can stand. I think you should be able to get jitter down to 5-10 msec
this way in W988 (it will be worse than this, probably, in NT or W2000).
