Use controller assignments Expert view in Logic Pro for Mac
You can use Expert view to make advanced controller assignments. These include Logic Pro parameters other than channel strip and plug-in parameters. For example, you can assign controllers to global, automation, and control surface group parameters in Expert view. You can also edit controller assignments in Expert view and can define zones and modes that let you switch between groups of controllers.
The Learn process opens the Controller Assignments window in Easy view, which shows basic parameters for the current assignment. To make assignments other than channel strip or plug-in assignments or to edit other assignment parameters, you need to switch to Expert view.
When Enable Complete Features is selected in Logic Pro > Settings > Advanced, Expert view is available.
Tip: You can only switch back to Easy view if a track or plug-in parameter is selected.

The Expert view window contains the following:
Zone list: Displays available zones for the device. The No Zone entry is for zoneless assignments—assignments that are always active, regardless of the active zone. Select a zone in the list to see associated modes (in the Mode list), and current assignments (in the Control/Parameter list). You can also double-click a zone to rename it. For more information see Use controller assignments zones and modes in Logic Pro for Mac.
Mode list: Displays modes for the currently selected zone. The No Mode entry is for modeless assignments. Select a mode in the list to see corresponding assignments in the Control/Parameter list, and to make it the active mode for the selected zone. You can also double-click a mode to rename it. For more information, see Use controller assignments zones and modes in Logic Pro for Mac.
Control/Parameter list: Select the assignment you want to edit. The left column displays the name of the control and the right column displays the (abbreviated) name of the parameter being controlled. The parameters of the selected assignment appear in the fields to the right of the list. For more information, see Controller assignments Control Name and Label fields in Logic Pro for Mac.
Note: You can select multiple assignments in the list, but only the parameters of the first selected assignment are displayed. When multiple assignments are selected, operations performed via the Edit menu can be applied to all selected assignments. All other operations apply only to the first assignment.
Controller Assignment Parameter area: All aspects of the selected controller assignment parameter are shown, and can be changed, in this area. For more information, see Controller assignments Expert view parameters in Logic Pro for Mac.
Input Message area: The port and MIDI input message can be altered directly. Some fields in this section are displays only and cannot be changed. For more information, see Controller assignments Expert view Input Message parameters in Logic Pro for Mac.
Value area: The range of values, and response, of the controller assignment to incoming messages is set in this area. Feedback to the display of control surfaces can also be determined here. For more information, see Controller assignments Expert view Value parameters in Logic Pro for Mac.
