When playing a WAV file as part of a Montage M performance, I've noticed that any Program changes I send while that WAV file is still playing are ignored by the Montage M. Is this expected behavior?

This can be a problem trying to quickly change from one performance to another using MIDI since you cannot always tell exactly when a playing WAV file ends as there's often a bit of 'dead air' at the end of the recording.
