The ReferenceToMusicTime method converts a performance time in REFERENCE_TIME format to a performance time in MUSIC_TIME format.
HRESULT ReferenceToMusicTime( REFERENCE_TIME rtTime, MUSIC_TIME* pmtTime );
Time in REFERENCE_TIME format.
Address of a variable that receives the converted time in MUSIC_TIME format.
If the method succeeds, the return value is S_OK.
If it fails, the method can return one of the error values shown in the following table.
Because music time is less precise than reference time, rounding occurs.
This method converts a time offset from the start of the performance, not a duration. Because the ratio between music time and reference time units depends on the tempo, DirectMusic takes into account all tempo changes since the start of the performance when calculating prtTime. If a master tempo has been set for the performance, it is taken into account as well.
