My preset sound changes in Mainstage

MainStage 3When opening our plugins in Mainstage, you may notice that your preset sound is different than normal. 

This is actually not a bug !

When you instantiate a plugin, Mainstage automatically sends a 127 expression pedal message.

As in V-Collection 5, every modulation sources (Modwheel, Exp pedal...) are systematically assigned to modulation destinations. (Vibrato, VCO FM etc...)

This 127 expression pedal value sent modifies the associated parameter and changes your preset sound.
