How MainStage Passes Through MIDI Messages
When MainStage receives incoming MIDI messages from your keyboard controller (or
other MIDI device), they are “passed through” if no screen control in your current layout
is assigned to receive that type of MIDI message (as set in the Number pop-up menu of
the Layout Inspector for the screen controls).
If a screen control for that type of MIDI message exists, the data is not passed through
if the MIDI Thru pop-up menu is set to “Do not pass through.” This is the default for
most screen controls when you add them to a layout. The exceptions are screen
controls assigned to the following MIDI message types: modulation, pitch bend,
sustain, expression, and aftertouch. By default, when you add one of these screen
controls, the MIDI pop-up menu is set to Automatic. The reason for these exceptions is
so that when you add a screen control for a modulation wheel or a sustain pedal, for
example, it “automatically” responds to the appropriate MIDI message type, without
your having to configure it further. If you want to have the screen control respond to a
different type of MIDI message, you can choose another MIDI message type from the
Number pop-up menu in the Layout Inspector.
Incoming MIDI messages that are passed through are passed to any channel strips
mapped to the same device sending those messages (that is, to the keyboard
controller you are using to “play” those channel strips). If there is no matching device,
the MIDI messages are sent to all channel strips.
