StagePlayer is a macOS Audio Unit (AUv3) instrument plugin built specifically for Apple MainStage. It gives you 16 independent audio tracks and 16 independent MIDI tracks in one plugin instance, letting you run backing tracks and automation — lighting cues, patch changes, outboard gear — from a single, reliable source during a live show.

MainStage's Playback plugin handles audio only — it has no way to send MIDI automation. StagePlayer adds full MIDI track support alongside audio, so cues, program changes, and CC automation can run in perfect sync with your tracks, all from inside MainStage.
