If you are using the ‘Avid Duet for Pro Tools’ (the all-black version that comes bundled with Pro Tools software), it will not show up in the ‘Apogee Maestro’ application. You will need to install the ‘Pro Tools I/O Control’ app from Avid’s website. Once you download and install this app, you should launch the ‘Pro Tools Duet Firmware Updater’ (found in Applications>Utilities>’Pro Tools Duet Firmware Updater’) and confirm that the firmware is up to date and then launch the ‘Pro Tools I/O Control’ app from your Applications folder.
