Automatic MIDI controller assignment in Logic Pro
Logic Pro supports automatic assignment of hardware controls for a variety of USB MIDI
controllers. When a supported USB MIDI controller is connected, the knobs, sliders, and
other hardware controls on the controller are automatically assigned to Smart Controls and
other functions in Logic Pro.
• Buttons are assigned to button screen controls. Buttons for common transport functions
(including Play, Stop, Pause, Record, Cycle and others), marker functions (including
Previous Marker, Next Marker, and Add Marker), and other functions are assigned to the
corresponding key commands for these functions.
• Knobs are assigned to knob screen controls.
• Faders are assigned to fader screen controls, with the following exception: when the
controller has only one fader, labeled Volume, that fader is assigned to Mixer volume for
the selected channel strip. For devices without knobs, faders may also be assigned to
knob screen controls.
Enable a USB MIDI controller for automatic assignment
The first time you connect a supported USB MIDI controller, a dialog appears, asking if you
want to use the device as a control surface.
To have Logic Pro automatically assign the controls on the device to Smart Controls and
other functions: click Auto Assign.
To use the device as a MIDI controller without automatic assignment: click No.
You can change the setting for each connected device in Logic Pro X > Control Surfaces >
Preferences > MIDI Controllers. For more information, see MIDI Controllers preferences and
the Logic Pro Control Surfaces Support manual.
Map screen controls automatically in Logic Pro
When you choose Automatic Smart Controls as the layout, all screen controls are mapped
automatically. You can also automatically map screen controls for a Smart Control for which
you have chosen a layout, in which case Logic Pro determines an appropriate mapping for
the screen controls.
Automatic mapping is useful when you have added plug-ins to an empty channel strip, for
tracks with Apple Loops, and with projects created in previous versions of Logic Pro.
When Show Advanced Tools is selected in the Advanced preferences pane, you can
automatically map all screen controls in the current Smart Control, or only unmapped
screen controls. In order to map screen controls, the Smart Control (and the track) must
have at least one plug-in inserted.
Apply automatic mapping to a Smart Control
1. In Logic Pro, in the Smart Controls pane, click the Inspector button in the Smart
Controls menu bar.
2. In the Parameter Mapping area, click a mapping, then choose one of the following:
• To map all screen controls: Choose Map all Controls.
• To map only unmapped screen controls: Choose Map all Unmapped Controls.
