And are there any plans for Apple to fix this? Our app makes important use
of this. When I was researching this problem, I downloaded the QuickTime
SDK and the sample projects exhibited the same problems, so I doubt it is
anything we are doing wrong. Also, I have tried many other apps (Digital
Performer 2.7/FreeMIDI 1.45 with QuickTime built-in synth, MasterTracks Pro
in Built-in Synth Mode, QT player [which did NOT work for me], etc.) that
seem to exhibit the same problems: choppy playback, static-like playback,
uneven playback, etc. The problem seems to occur with virtual memory on or
off, although sometimes changing that setting would make a difference in the
"severity" of the poor playback.

Anybody have more info on this? Possible work-arounds? Known good/bad OS
system combinations. I had been testing this mostly on 9.0.4. I have heard
of similar problems from our QA department on problematic playback in 9.1
and 9.2 also.

Thanks,
