How to Connect Your Hardware for Logic Pro X
If you plan on recording audio, you’ll need a way to get audio into Logic Pro. Your Mac probably has a built-in line in or microphone. These may work in a pinch, but professional-quality recordings need professional hardware. Luckily, most professional hardware is compatible with Logic Pro X, so you should have a simple plug-and-play experience.
After you connect your audio hardware, you tell Logic Pro how to use it by choosing Logic Pro X→Preferences→Audio. Select the Devices tab and use the Output Device and Input Device drop-down menus to choose your audio hardware.
You can get to Logic Pro X Preferences quickly by pressing Command+comma (,). This key command will display the Preferences in most applications on your Mac.
Similarly, if you plan to control Logic Pro from a MIDI controller, your computer needs to be connected to the controller. Many controllers will send and receive MIDI through USB, eliminating the need for a third-party interface. Other controllers may use 5-pin DIN cables and require a hardware MIDI interface to go between the computer and the controller. Check the literature; Logic Pro will probably be mentioned.
After you’ve connected your MIDI controller, Logic Pro will automatically listen for your controller’s signals on the currently selected track. Playing software instruments with a MIDI keyboard controller is usually a plug-and-play experience without any need for customization.
With all your hardware connected, Logic Pro X is ready and waiting for your commands.
