Only one set of assignment parameters is visible at a time in Easy view. You use the Learn process to assign controllers to channel strip and plug-in parameters by moving a controller on your control surface. This sends a MIDI message to Logic Pro for Mac, thus “teaching” it which controller you are assigning to the chosen parameter.
In the Logic Pro Mixer, or in any plug-in window, select a parameter.
Choose Logic Pro > Control Surfaces > Learn Assignment for [parameter name].
Alternatively, you can use the Learn new Controller Assignment key command to open the Controller Assignments window and automatically activate Learn mode.
The Controller Assignments window opens in Easy view, with the Learn Mode button activated. In most cases, the name of the selected parameter is shown in the Parameter field.
Move the hardware controller you want to assign to the selected parameter, then click the Learn Mode button to complete the Learn process.
Moving the controller sends a MIDI message to Logic Pro, which appears in the “Input message” field. This memorizes the controller assignment.
If you do not click the Learn Mode button, Learn mode remains active, allowing you to make further assignments.
To make another assignment, select another parameter, then move the controller on the control surface.
Click the Learn Mode button (or press Command-L) to complete the Learn process.
Choose Logic Pro > Control Surfaces > Learn Assignment for [parameter name] (or press Command-L) to open the Controller Assignments window.
Hold down the modifier key you want to use (Command, for example) as you select the parameter you want to assign, while moving the control.
Click the Learn Mode button to complete the Learn process.
If Logic Pro receives a MIDI message from the device while you are holding down the modifier key, the Learn Mode button is deactivated when you release the key, and the Learn process is complete. If you release the modifier key before Logic Pro receives a MIDI message, the Learn Mode button remains active, so you can still move a controller to send a MIDI message. In this situation, be sure to click the Learn Mode button when you are finished to end the Learn process.
Logic Pro includes a shortcut that makes it easy to assign a series of controllers to a series of similar parameters. For example, you can use this shortcut to assign a series of faders to volume; to assign a series of knobs or switches to other channel strip parameters such as pan, solo, or mute; or to assign a series of controllers to a set of plug-in parameters.
In the Logic Pro Mixer, or in any plug-in window, select a parameter.
Choose Logic Pro > Control Surfaces > Learn Assignment for [parameter name].
Alternatively, you can use the Learn new Controller Assignment key command to open the Controller Assignments window, and activate Learn mode.
The Controller Assignments window opens in Easy view, with the Learn Mode button activated. In most cases, the name of the selected parameter is shown in the Parameter field.
Assign the first controller in the series to the first parameter. For example, assign fader 1 to control volume for channel strip 1.
Assign the last controller in the series to the last parameter. For example, assign fader 16 to control volume for channel strip 16. The number of controllers between the first and last in the series must match the number of parameters between the first and last parameter. In the example, the distance between 1 and 16 would equal 15.
A “Do you want to fill up in between?” dialog is shown.
To automatically fill the controllers between the first and last with the corresponding assignments, click OK.
Note: You can only use shortcuts for knobs that send a single channel message, where the first data byte is the controller number and the second data byte is the value. Alternatively, the controller number can be encoded in the MIDI channel, with a fixed first data byte. Consult the documentation that came with your device for information on its data structure.
In Logic Pro, select the assignment you want to remove in the Controller Assignments Easy View window, then click the Delete button.
