Not directly.

However, with Panther (and the QT updates for Jaguar) we added an API for this to scale the playback rate - this is how you'd synchronise as this can be done dynamically and as often as you need to. See MusicPlayerSetPlayRateScalar - So, you'd have to parse the MIDI beat clock yourself, but then you can make the adjustments to playback rate accordingly (though it won't play backwards)

MusicPlayerSetTime is a very disruptive event and is *not* recommended for use in this kind of scenario (though of course if you actually jump to a different time then you would use this API) - but not to track the normal playing mode (including going faster or slower) you shouldn't use this API...

Is it possible for MusicPlayer to behave as a slave to MIDI beat clock?
I have not tried this, but the only way that I can see being able to
do this is to constantly call MusicPlayerSetTime() and also send tempo
events, both 24 times per quarter note? Would that be bad? I imagine
drastic tempo changes could result in lost notes, no?
