DMUS_TRACKF_FLAGS
The DMUS_TRACKF_FLAGS enumerated type is used in the dwFlags parameter of the IDirectMusicTrack8::Play and IDirectMusicTrack8::PlayEx methods.

} DMUS_TRACKF_FLAGS;
Constants
DMUS_TRACKF_SEEK
IDirectMusicTrack8::Play was called in response to seeking, meaning that the mtStart parameter is not necessarily the same as the mtEnd of the previous call.
DMUS_TRACKF_LOOP
Play was called in response to a loop.
DMUS_TRACKF_START
This is the first call to IDirectMusicTrack8::Play. DMUS_TRACKF_SEEK can also be set if the track is not playing from the beginning.
DMUS_TRACKF_FLUSH
Play was called in response to a flush or invalidation that requires the track to replay something that it played previously. In this case, DMUS_TRACKF_SEEK is set, as well.
DMUS_TRACKF_DIRTY
A control segment has begun or ended. Tracks that normally wait until mtNext to call IDirectMusicTrack8::GetParam orIDirectMusicTrack8::GetParamEx should make the call right away, instead of waiting, because their data might now be invalid. For more information on setting control segments, see DMUS_SEGF_FLAGS.
DMUS_TRACKF_NOTIFY_OFF
Track is not to send notifications.
DMUS_TRACKF_PLAYOFF
Track is not to play, but can still send notifications.
DMUS_TRACKF_LOOPEND
End of range is also a loop end.
DMUS_TRACKF_STOP
End of range is also end of playing this segment.
DMUS_TRACKF_RECOMPOSE
Track should be recomposed on each loop. A signpost track is recomposed using a different chord progression, and a melody formulation track is recomposed using different melody fragments.
DMUS_TRACKF_CLOCK
Time parameters are in reference time. Valid only for IDirectMusicTrack8::PlayEx.
Remarks
When Play is called in response to a repeat, DMUS_TRACKF_LOOP and DMUS_TRACKF_SEEK are set.
To support invalidation, tracks must support seeking..
