Don't want to derail the OP's original thread because this is about Garritan. Have GPO and it is great for layers...
Went for Bit's recommendation on Solid State Symphony for $40. The thing is incredible!! Best money I've spent on any Kontakt library. Got a synthetic touch that die hard purists may not like, but as close as it gets otherwise, with the ability to warp things if needed. The differential velocity for the layers gives unique expressive power.
Clarifying the free Kontakt player limitations Smokey mentioned. 15 minute time out before having to reload again is the issue.
Bit, owe you a cold sterno or two if you wander this way down south.
