Keyboard screen control parameters
If you are using a keyboard controller or another MIDI device that sends MIDI note messages, your layout should include a keyboard (or MIDI activity) screen control. You can edit the following parameters for keyboard screen controls.
Device pop-up menu: Shows the name of the learned keyboard. The device name may correspond to the name of the keyboard controller, or to a port on the controller, if it has multiple ports. You can choose another device or choose All.
Channel pop-up menu: Shows the MIDI channel on which MainStage receives input from the keyboard. You can choose another channel or choose All.
Velocity Sensitivity slider: Sets the velocity sensitivity for the keyboard. Less means that higher velocities are required to trigger the maximum value, while More means that lower velocities trigger the maximum value.
Name field: Enter a name for the keyboard. The name appears in the Input pop-up menu in the Channel Strip Inspector, where you can select the device the channel strip responds to.
Number of Keys value slider: Enter the number of keys to display on the keyboard screen control.
Lowest Key value slider: Enter the note name for the lowest key.
Lowest Key Learn button: Click the Learn button, then press the lowest key to have MainStage learn it.
The Number of Keys and Low Key affect only the visual appearance of the screen control. They do not affect what notes are received from your keyboard controller.
Display keyboard layers checkbox: When active, a layer is displayed above the keyboard in the workspace for each software instrument channel strip in a patch. The layers show the name and color of the channel strip and respond when you play the keyboard.
Height value slider: Sets the height of the layer display that appears above the keyboard.
