Well guess what I found - a folder called Apple Loops for Garageband...
I was searching for all GarageBand related files in order to delete them and try to reinstall the app. I found this folder, opened it up, and lo and behold there are 1,699 .aif and .caf files. But it appears that the .aif loops are the ones that appear in the loop browser of GB but produce the message saying I need to download and install the complete set. The .caf loops on the other hand seem to be working as expected.
So I guess my quesiton has changed a little. Does anybody know why the .caf files would be working while the .aif file wouldn't. Any idea how to get GB to recongize and use them?
Thanks for the suggestion leonieDF. I dragged all of the loops into the browser and GB did it's little process of indexing them. However, I now have a lot of duplicates - one of which plays and another which prompts me with the message, "The Software Instrument or Apple Loop selected is not currently installed on your computer. Would you like to install the complete set of GarageBand instruments and loops?"
Here's what my loop browser looks like now:
Do you happen to know how to get rid of duplicates?
Sorry for that! Hopefully rebuilding your loop index will solve this.
To create a new loop index, that does not contain the references to the missing loops, remove the contents of the old loop index from the Apple Loops Index folder and then again drag the loops to the loops browser.
- Quit GarageBand if it is running.
- Remove the contents of the folder /Library/Audio/Apple Loops Index/ to another folder on your Desktop.
- Relaunch GarageBand - now the Loop Browser should appear completely empty.
- Drag all folders with loops onto the Loop Browser in GarageBand. This will reindex the Loops. After this, only loops installed on your machine should appear in the Browser.
P.S. if still broken references appear, you may have more than one loop index folder in your library. Then you need to search your library with Spotlight for all instances; see here:
