After you have created a concert with your custom patches following the steps described above, you’re ready to play. When you perform live, you can use your computer as the final sound module and effects box in your rig. You can select a patch and start playing it instantly. MainStage switches seamlessly between patches and can sustain notes from the previous patch while you start playing the newly selected one. You can view feedback about your patches, including names, parameter values, and audio output levels, in real time. You can also adjust concert-wide effects using auxiliary channel strips and control other concert-wide settings.
In Perform mode, the workspace fill your entire screen by default, optimizing available screen space for your onscreen layout. You can also choose Perform in Window to have the workspace fill the MainStage window, while retaining access to the Finder and to other applications.
You can use MainStage with multiple MIDI controllers, microphones, musical instruments, and other music equipment. For time-based effects such as reverb and delay, you can set a pre-defined tempo, use MIDI input for tempo changes, or tap the tempo as you perform.
