What is the “track” mixer?
To have the VS be in the “track” mixer mode, press the FADER [EDIT] button until it turns green. The track mixer is where you can playback/listen to tracks that have already been recorded or are in the process of being recorded. The track mixer is also used when you want to mixdown or bounce tracks. When bouncing tracks, one or more tracks will be in the play condition (source tracks), and one or more tracks will be in the record condition (destination tracks).
