164 Chapter 8 Basic Operations
Assigning Key Commands to Control Surfaces
The Learn New Assignment button allows you to assign control surface messages to
particular commands—effectively teaching Logic Pro to understand these messages.
To learn a controller assignment:
1 Click the Learn New Assignment button.
2 Select the command in the Command column.
3 Send the desired MIDI message from your controller.
The Assignments field displays the learned assignment. This may show 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, if applicable.
Note: The Learn New Assignment button is automatically turned off 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. To ensure reliable reception, hold the
button for a short period before releasing it.
4 If you want to make another assignment, repeat steps 2 and 3.
