StagePlayer
StagePlayer is a multitrack Audio Unit (AUv3) instrument built specifically for live performance inside Apple MainStage.
Most backing-track tools are built for the studio. StagePlayer was built for the stage — 16 independent audio tracks and 16 independent MIDI tracks in a single plugin instance, with a transport that runs entirely on its own terms, unaffected by anything else happening in your session.
Beyond playback, StagePlayer drives your entire show's automation: Program Changes, CC automation, and precise MIDI events routed independently, per track, to MainStage's own controls, your lighting rig, your video software, or outboard hardware — all perfectly in time with the music, every single time.
Marker-based looping for rehearsal, a full tempo map, drag-and-drop editing, and project files that travel cleanly between machines round it out — a complete toolset for running a show, in one plugin.
