Output windows provide the essential track mixing controls (such as track panning and volume), as an alternative to Mix and Edit window views. Multichannel Output and Send windows also provide expanded Panner views, and other surround-specific controls. See Surround Panning and Mixing.Output windows are useful in large sessions to leave important tracks in an anchored location, unaffected by Mix and Edit window (or control surface) banking. See Output Windows for Tracks and Sends.
