If you have loop libraries or individual loops that are not Apple Loops, you can add them to the Untagged Loops tab of the Loop Browser. Because these loops don’t have the all the tags, or embedded information, that Apple Loops do, they don’t offer the full functionality of Apple Loops. However, you can preview untagged loops at their original tempo or the tempo of the current project, batch analyze them for tempo information, remove any existing tempo information, and synchronize the playback of untagged loops with your project.
When you drag one or more untagged loops into the Untagged Loops tab of the Loop Browser, the loops are added to a special Untagged Loops folder on your hard drive. You can also manually drag loops and folders of loop libraries into this folder. Once added, untagged loops are always available to any project using this folder.

Do one of the following:
Drag a loop or folder containing loops into the Untagged Loops tab of the Loop Browser.
In the Finder, copy a loop or folder containing loops to Music > Audio Music Apps > Untagged Loops.
In the All Files Browser, right-click a folder and select “Add to Untagged Loops Library” from the shortcut menu.
Right-click in the Untagged Loops tab and select Preview > At Project Tempo from the shortcut menu.
Click the Play button at the bottom of the Loop Browser to play the loop.
Drag the Volume slider at the bottom of the Loop Browser to adjust the volume of the loop you’re listening to.
Right-click in the Untagged Loops tab and select Preview > At Original Tempo from the shortcut menu.
Click the Play button at the bottom of the Loop Browser to play the loop.
Drag the Volume slider at the bottom of the Loop Browser to adjust the volume of the loop you’re listening to.
