Transpose individual software instruments in MainStage
In the Channel Strip Inspector, you can transpose (change the pitch of) the MIDI notes being received by a software instrument. When you transpose MIDI notes, the pitch of every MIDI note received by the software instrument assigned to the channel strip is transposed by the number of semitones set in the Transpose value slider. If a software instrument is unpitched—such as a sound effect or a percussion sound that doesn’t change in pitch regardless of the MIDI note received—you can also set the instrument assigned to the channel strip as unpitched even if all the other instruments in the patch are being transposed.
In MainStage, select the channel strip in the Channel Strips area.
In the MIDI Input tab of the Channel Strip Inspector, set the value using the Transpose value slider. You can drag the value up or down to set the value, click the Up Arrow or Down Arrow, or double-click the value and type a new value.
In MainStage, select the channel strip in the Channel Strips area.
In the MIDI Input tab of the Channel Strip Inspector, select the Unpitched checkbox.
The software instrument’s output remains unpitched even if the rest of the patch receives transposed MIDI notes.
