Record your performances
You can record a performance to an audio file. Before you record a performance, you can choose the file format of the recorded audio file.
If you choose AIFF as the file format for recording, the maximum file size for the recorded file is 2 gigabytes. If you choose WAVE as the file format, the maximum file size is 4 gigabytes. If you choose CAF as the file format, there is no practical limit to the file size. You can choose the file format in MainStage > Preferences > Audio, and also set the location of the recorded file and choose which audio outputs are recorded (if you are using multiple sets of outputs in your concert). For information about recording preferences, see Audio preferences.
You can record in Perform mode by mapping a screen control to the Record action. You can also assign a key command to the Record action and use it to record in Perform mode (but not in Perform in Full Screen).
