What is your favourite Garritan Library!? I would have to say that mine is Garritan Instant Orchestra. I generally compose with full ensembles and not so much on the solo part, so GIO has really helped out a lot. I love the harp in GIO, it's still one of my favourites. The choir is also good. It has a different kind of a sound that you don't find in these big expensive choir libraries. I find the GIO choirs really haunting and warm.
