I just installed it, thinking it was going to be a big to-do to make it playable, and boy was I in for a surprise. You just open it up and start playing... and BOY is it amazing. I watched the visual demo on the Garritan site to see the guy playing this cello in realtime, and I thought "there's no way it could be that easy" -- yet 5 minutes later, I'm sitting here doing exactly that. It's the most expressive, realistic cello I've heard yet.... awesome, awesome work, Garritan guys. I'm really impressed.
