The DirectMusicPerformance.GetMasterTempo method retrieves the current master tempo.
object.GetMasterTempo() As Single
If the method succeeds, it returns a value in the range from 0.25 through 2.0.
If the method fails, it raises an error, and Err.Number is set.
The master tempo is a scaling factor that is applied to the tempo by the final output tool. By default it is 1. A value of 0.5 would halve the tempo, and a value of 2.0 would double it.
