Learn a controller assignment
1 Click the Learn New Assignment button.
2 Select the command in the Command column.
3 Send a MIDI message from your controller.
The Assignments field displays the learned assignment, showing one or all of the following:
•
The name of the control surface—or the MIDI string, if the assignment is from an unsupported
control surface
•
The name of the control
•
The zone and mode that the assignment belongs to
The Learn New Assignment button becomes unavailable when the entire message has been
received. This avoids reception of further messages that may be sent by the device when you
release the button.
