How to Load an AU Instrument in Logic Pro

If you've just installed a new Audio Unit (AU) instrument and are eager to use it in Logic Pro, you're in for a smooth ride. Logic Pro supports AU plugins natively, making it easy to integrate third-party instruments into your workflow. Here’s a quick guide to get you started:

Open a New Software Instrument Track

  • Launch Logic Pro.
  • Click the ‘+’ button above the track list to add a new track.
  • Choose Software Instrument, then click Create.

Access the Instrument Slot

  • On the new track, locate the instrument slot in the channel strip (it’ll say something like “E-Piano” by default).
  • Click on this slot to open a drop-down menu.

Load Your AU Instrument

  • In the drop-down menu, hover over AU Instruments.
  • Find the developer name of your plugin, then select the plugin from the list.
  • Your AU instrument will now load into the track.

Start Playing

  • You can now use a MIDI keyboard or draw MIDI notes in the Piano Roll to play your new instrument.

Troubleshooting Tip

If you don’t see your AU instrument listed, make sure:

  • It's installed correctly.
  • Logic Pro has scanned it (restart Logic if needed).
  • The plugin is Apple Silicon compatible (if you're using an M1/M2 Mac) or running in Rosetta mode if needed.

Now you’re all set to explore your new sounds and get creative!
