Add a control surface to Logic Pro — Apple Support
Some control surfaces such as Mackie Control are detected automatically when you open Logic Pro. You can add other devices that are not detected automatically using the Setup window. See the installation and setup information in the support materials for your particular device. Some devices may require different or additional steps, but in most cases you only need to select the name of the device you want to use with Logic Pro, then add it. When you add a control surface device, it is represented by an icon in the Device area of the Control Surface Setup window.
