Playback and Mixing
In order to play audio or MIDI files, they should be opened in a track. To play a track, you should activate its Play button (it turns green) and start the transport.
Tracks have mixing and effect processing capabilities. You can expand the mixer by adding any number of Group or Effect Return sections. All Tracks, Groups, and Effect Returns are routed through the Master section.
Playing MIDI
If the Instrument slot contains an External MIDI Instrument, the track's output will be sent to the corresponding MIDI Out Device. In this case, the track is not affected by any Group, Effect Return, or Master sections.
If a software instrument (Sampler, instrument plugin, etc.) is used the track's output is treated as if it's an audio track.
If a track's Play button is engaged and the transport is running, all streams in the track will be played.
