Get started with Apple Loops — Logic Pro X

Apple Loops are prerecorded musical patterns that you can use to quickly add drum beats, rhythm parts, and other musical phrases to a project. Apple Loops contain musical patterns that can be repeated over and over, seamlessly. After you add a loop to the Tracks area, you can extend it to fill any amount of time. When you add an Apple Loop to a project, it automatically matches the project tempo and key.
