Would like to have click, document scroll, and music all start with push of button, or even better, press of airturn pedal. How can I do this?
To start all those functions when you select a song, go to Layouts > [layout name] > Edit Details > Song Selection Actions and turn on the desired actions.
To select a song from an AirTurn pedal (which in turn will trigger those actions), see the instructions on this page:
