Vocalists and acoustic musicians can use MainStage by sending the audio output from a microphone connected to their computer to audio channel strips in their patches. You can use MainStage with Core Audio-compatible audio devices, such as audio interfaces and digital mixers, for input from instruments and microphones, and for audio output to speakers, monitors, a mixing board, or a public address (PA) system. In MainStage, you can access a wide range of effects in your patches.
Drummers can also use MainStage by sending the audio output from microphones to audio channel strips in their patches or by using drum pads or a virtual drum kit to control the EXS24 mkII sampler, Ultrabeat, and percussion-oriented plug-ins.
