Play Apple Loops
After searching for loops in the Loop Browser, you can listen to the results to find the loop that sounds best in your project. When you listen to a loop, you can hear it by itself (solo), or play it together with the project.
Play a loop
Select a loop in the results list.
The loop plays back in the project’s tempo and key. If the project is playing, the previewed loop plays back in sync with the project.
Drag the Volume slider at the bottom of the Loop Browser to adjust the volume of the loop you’re listening to.
Click the loop again to stop playing.
