I've been on the hunt for my missing GarageBand loops for some time. I just realized: GarageBand hides loops that it finds "inappropriate" for the currently selected key signature. Yes, this is just stupidity on my part for not noticing this sooner (what can I say, I like C major), but I want it to end now. I want to be able to see all of my loops regardless of what key I'm in. How do I go about doing this?
