Playing Back Audio
You can play back audio les while you are performing in
MainStage and control playback in a variety of ways.
Playing back audio has several uses, including playing backing tracks to accompany
your performance, playing song stems that you can mix live, and creating a virtual
band that you can use to rehearse your performance.
You play back audio les using the Playback plug-in, which is available only in
MainStage. The Playback plug-in supports several le formats, including AIFF, WAVE,
and CAF. You can also play back les that include markers, including bounced les from
Logic Pro projects and Apple Loops. When you use audio les that include markers
with a Playback plug-in, you can use the markers to play back dierent parts of the
audio le.
You can start and stop a Playback plug-in in real time as you perform and map screen
controls to other Playback parameters to control them while you perform. The Screen
Controls Palette includes a waveform screen control that you can use to view the audio
waveform of the audio le for a Playback plug-in and a progress indicator that you can
use with the Cycle feature of the Playback plug-in.
