620 Chapter 28 Creating Apple Loops
The ReCycle files are converted to Apple Loops (the slice points are converted to
transient positions) and copied to the chosen location.
Adding Apple Loops to the Loop Browser
Logic Pro must index Apple Loops before they are shown in the Loop Browser. Loops
can reside in any directory, but you need to tell Logic Pro where to find them.
To add Apple Loops to the Loop Browser:
1 Open a Finder window alongside Logic Pro.
2 Navigate to the folder that contains the Apple Loops.
3 Select the Apple Loops in the folder and drag them into the Loop Browser.
The loops are added to the Apple Loops library and indexed. When this process is
finished, the loops will be available directly in the Loop Browser.
If you drag a single loop to the Loop Browser, the loop will be copied to ~/Library/
Audio/Apple Loops/User Loops/SingleFiles.
If you drag a folder of loops that are located on the same drive and partition as the
Loop Browser, the loops will be left at their current location, and an alias of the folder
will be created in ~/Library/Audio/Apple Loops/User Loops.
If the loops are located on a different drive or partition, you’ll be asked whether you
want to copy them to the loop library, or index them at their current location (loops
added from optical media will always be copied).
 If you choose to copy them, the folder containing the loops will be copied to ~/
Library/Audio/Apple Loops/User Loops/.
 If you choose to index them at their current location, an alias to the folder will be
created in ~/Library/Audio/Apple Loops/User Loops/.
Acid Loops in the Loop Browser
The Loop Browser also displays Acid Loops. Acid Loops don’t contain tags like Apple
Loops. In Acid Loops, this information is derived from the surrounding folder structure
(especially the names of folders), which must comply with certain standards. This
means that it’s not possible to drag an individual Acid Loop file into the Loop Browser.
As such, you need to drag the entire CD (or folder) that contains the Acid Loops into
the Loop Browser.
