Tom,
It is possible to perform many operations on a MusicTrack while it is playing,
for example cut, copy, paste. Unfortunately, changing the tempo while
it is playing is currently not supported. We realize this is a good thing
to be able to do and we have a bug open about it so this problem may be
addressed in a future release...

Is it possible to adjust a MusicTrack while it is playing? What I
have now is a music track with a single note that simply loops, and
I'd like to adjust the tempo of the track without having to stop it.
I've tried getting the tempo data with
MusicEventIteratorGetEventInfo and changing the value in the
returned structure, but that doesn't seem to work (or I'm doing it
incorrectly).
Any help is appreciated. I'm new to programming with CoreAudio and
I'm finding the documentation a little sparse.
Thanks,
Tom
