Yeah, I got in on the initial $.99 release too, and the v2 update didn't cost a thing either! I've yet to buy an audio/MIDI dock, so the new 4-track sequencer makes it less of a toy and more of a tool for me.
I had some time to mess w/ the GD timbres, and if you tweak the filter section along w/ the path rate, you can make out that some of the clips were lifted from an ensemble performance. But like Edwin says, if you're hoping for samples of Phil's EB-0 running thru a freqbox, this is slightly removed.....
If I recall correctly, this was the show where Jerry threw Phil down the stairs afterwards?!?
