Soundtrack Pro: How to use AJA Io to monitor audio

You can use the AJA Io, an external output device, to monitor audio with Soundtrack Pro. However, setting up the Io is different that setting up a typical Core Audio interface. Here's how to do it:

1. Import a video into a Soundtrack Pro project to monitor audio through the AJA Io.
2. Open the Soundtrack Pro preferences (Soundtrack Pro > Preferences).
3. Click the Video Out button.
4. Select the appropriate AJA output option from the Video Out pop-up menu.

   

5. Make sure video out is enabled. You can toggle Video Output on and off by pressing Command-F12. (Soundtrack Pro playback must be stopped while toggling the setting).
