I've tried a couple so far, and they aren't accessible till you do some hot spots, but then you can really get to the presets anyway and the sounds are just so nice! I'm gonna get them and build them with some sighted asistance. Course I'll send them to Phil when I'm done, unless one of you folks that are really good at it decides to do it, then I'll wait patiently, but ya have to hurry cause they're just lots of fun to play with.
