MainStage: Pressing buttons on a control surface triggers notes
When you press buttons or controls on an attached control surface, notes are triggered on the currently selected instrument in MainStage.
This is expected. MainStage does not offer control surface support, and will treat incoming data from control surfaces as normal MIDI data. This may lead to unwanted triggering of notes, or other undesired results. Avoid using control surfaces when running MainStage.
