When feedback protection is turned on for a channel strip, MainStage alerts you when it
detects feedback on the channel. When the feedback alert appears, the channel is temporarily
silenced. You can then choose to mute the channel while you find and eliminate the source
of the feedback, disable feedback protection for all audio and external channel strips in all
concerts, or continue to use the channel and receive alerts when feedback occurs.
For more information about enabling feedback protection globally (in MainStage >
Preferences > Audio), see Audio preferences in MainStage.
Set keyboard input for a software instrument channel strip in MainStage
In the Channel Strip Inspector, you can choose the keyboard controller from which the
channel strip receives MIDI input. For multitimbral instruments, you can also choose
the input for each MIDI channel. For example, when using the EVB3 instrument as a
multitimbral instrument, you can send input to the upper and lower register and the
foot pedal using three separate MIDI channels.
For information about using keyboard controllers in performance, including using multiple
controllers, see MainStage tips for performing with keyboard controllers.
Set the keyboard input for a software instrument channel strip
1. In the MainStage Channel Strip Inspector, click the MIDI Input tab.
2. Choose the MIDI input device from the Keyboard pop-up menu in the Input section.
The names in the Keyboard pop-up menu correspond to keyboard screen controls in
the workspace.
Set multitimbral input for different MIDI channels
1. In the MainStage Channel Strip Inspector, click the MIDI Input tab.
2. Choose Multitimbral from the Keyboard pop-up menu in the Input section.
3. In the Multitimbral Settings dialog, choose the input device for each MIDI channel
you want to receive MIDI input.
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.
Transpose the MIDI input of a software instrument
1. Select the channel strip in the MainStage Channel Strips area.
2. 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.
