After considerable prodding from me Kirk Hunter is doing an EXS24 version of his Emerald Orchestral Library and he has added to it many things that will be in his new Ruby library. Kirk was new to Logic and the EXS24 is very impressed with its sound and cpu efficiency.
As Logic users well know practically the only thing that Logic does not come with is a good orchestral library and I am not aware of any for the EXS24 that comes even close to Emerald under $650.
I went out on a limb promising him that there was a market for this as the impending release of Redmatica's Keymap will make the EXS24 very powerful and flexible.
He is having a pre-sale where you can order Emerald for only $275. Listen to the demos. This is an incredible bargain.
