Okay, so today I wrote a song.. I recorded it, imported that in as a track, and then added three Software Instrument tracks. It was fine until about twenty minutes ago, when I finished the song. It's holding out notes that aren't supposed to be sustained on the Orchestral Strings. Like, the note ends but GarageBand keeps playing it. And playing it. And keeps playing every note after that so that it ends up being this awful buildup of clashing notes that won't end.

And I don't know why! It won't go away! I've been trying to figure out the problem, but I can't find anything. Nothing. And I know I'm living in GarageBand dark ages with version 2.0 :] but, please please please, if anyone has any advice on the matter... I'm at the bashing head violently into keyboard point about now.
