MainStage: Map screen controls to all channel strips in a patch
When you map a screen control to a channel strip parameter such as volume or pan, you can map it to control the same parameter in all of the channel strips in the patch. This is particularly useful when you want to control the overall volume of a layered sound, even if the different layers are played across multiple keyboards.
Map a screen control to all channel strips in a patch
Map the screen control to a common screen control parameter, such as volume or pan.
In the column on the left of the Parameter Mapping browser, select the Send to All folder.
Select the destination from the second column.
Select the parameter to map the screen control to from the third column.
You can map the screen control to actions for transposing software instrument channel strips, channel strip parameters, and MIDI control message types from the Destinations folder. When you map a screen control to all channel strips in a patch, the parameter to which the screen control is mapped changes to the same value for all channel strips in the patch when you move the screen control.
Note: When you map a drum map using Send to All, the Send to All folder contains MIDI notes, not controllers.
