The DirectMusicPerformance.SetMasterTempo method sets a scaling factor that is applied to the tempo.
object.SetMasterTempo(tempo As Single)
If the method fails, it raises an error, and Err.Number is set.
By default, the master tempo is 1. A value of 0.5 would halve the tempo, and a value of 2.0 would double it.
