Looping a Track To loop a track: Within the Tracks window, click the Loop icon next to the track named 'Drum Loop 120'. Set the track length (in the Bars column) for 'Drum Loop 120' to 2 bars. Looping a track causes it to repeat over and over from the beginning to end. Loop length is determined by the number in the Bars column (next to the Loop column). The next step in your first session is Recording Your First MIDI Track.
