Mapping Screen Controls
5
After you make connections between your MIDI hardware and
the screen controls in MainStage, you map the screen controls
to channel strip and plug-in parameters in your patches so you
can modify the patches in real time when you perform.
By mapping screen controls to different parameters in the patches in your concert,
you can control exactly the parameters you want for each patch. You can map a single
screen control to multiple parameters in the same patch or map screen controls
to MainStage actions to select patches, change the tempo, use the Tuner, display
information, and perform other functions.
