SOLUTION - Re-Index Loops when "Index Now" button is broken

Question

This message is for anyone having trouble with Soundtrack's loop indexing in the following way:
PROBLEM:
... You want to re-index some loops, or
... You want to de-index some loops, or
... Some loops are showing up red
AND...
... You cannot re-index from the "Setup..." button in the Search palette (the minus button and/or "Index Now" buttons are grayed out for some unknown reason)
*HERE IS THE POSSIBLE SOLUTION:*
... Delete all files from the following folders:
Library/Preferences/Soundtrack/
Library/Audio/Apple Loops Index/
... Now restart Soundtrack, and click "Setup...". All the indexed directories should be gone.
... You'll have to re-add and re-index your whole library. This may also affect GarageBand and/or Logic, and require re-indexing in them as well.
*If you're still having trouble...* there may be some more index files floating around your system. Open Spotlight and set "System Files are Included" and "File Name" in the search options and search for "search index". This should show you where any remaining Apple Loop search index files are located, so you can delete them. They will be named stuff like "Search Index E44B5969-5E4A-4E27-A3C2-E5861C5D1FB8.txt".
Hope this helps anyone else out there. It worked for me with Soundtrack 1.1 when my loops were all messed up.

Well, to add metadata and transients to sound clips you need to edit them in Apple Loop Utility which is included with Final Cut Studio.
To add custom loops to your permanent library you need to make a new folder like "My Loops" and put it somewhere permanent like in Library/Audio/Apple Loops and then index it with Soundtrack/GarageBand/Logic. Soundtrack uses the "Setup..." list and GarageBand you can just drag and drop into the loop browser. Not sure about Logic but it should be something similar.
If you wanted to edit the index files manually from the Finder, they are in some weird format and I don't think it's possible.
