MainStage features a metronome that you can use to play in time with the concert tempo. The metronome always plays at the current convert tempo.
You can have the metronome play different notes for different bars, beats, groups, or divisions. You can also choose a different sound for the metronome, change the audio output for the metronome sound, and change the volume of the metronome relative to the overall audio output.
In MainStage, do one of the following:
Click the Metronome button in the toolbar.
Click a button mapped to the Metronome action.
If you are using a Playback plug-in, click the Metronome button in the Playback window (or click a button mapped to the Metronome button).
To stop the metronome, click any of the listed buttons again.
Note: Starting the metronome also starts the MainStage clock if it is not already running.
At the concert level, you can also map a button or other screen control to the Metronome action (located in the Actions folder) and use it to start and stop the metronome.
If you are using a Mac with a Touch Bar, you can also press the Metronome button in the Touch Bar to start the metronome.
By default, the metronome sound is routed to the main outputs (Output 1-2). You can route the metronome to another output pair, which can be useful in performance when you want to hear the metronome sound through a separate audio output (for example, a headphone mix) and not through the main outputs.
