Dear John, on a Mac, the easiest way is to send the output of Pro Tools to a virtual sound card and then to select the virtual sound card as the microphone in FarPlay. Virtual sound cards on Mac include Existential Audio’s BlackHole (https://existential.audio/blackhole/ free donationware) and Rogue Amoeba’s Loopback (https://rogueamoeba.com/loopback/ $99 + tax).
VoiceMeeter is a virtual sound card available for Windows, but has a bit of latency. If you’re trying to send audio from Pro Tools to FarPlay in Windows, a better way would be to use your audio interface’s built-in loopback/routing feature (if available).
Are you using macOS or Windows?
