Add another loop and move it.

To build up the session, click to select another track, and choose Insert > Audio to add a second loop. Even if it was recorded at a different tempo, you can preview the new loop at the session tempo. In the Files tab of the Organizer window, make sure that the Follow Session option, the Loop button, and the Auto button are selected, and click the name of the loop. You can then use the spacebar to preview the rest of the session with that loop.

After you’re happy with the loop, drag it to where you want it to begin in the track. (Notice how a vertical line appears and the loop snaps to the beat in the track.) Then, drag the bottom right corner of the loop to extend it for as many repeats as you want.
