Loops, as described in Chapter 24, are among the greatest joys of GarageBand. So when they don’t work, they’re among the biggest disappointments.
Adding more loops to GarageBand isn’t just a matter of stuffing them into a certain folder on your hard drive. You also have to make GarageBand aware of them. To do that, you force GarageBand to index any new loops, building an internal card catalog of which loops you have and where they’re stored.
