I made the mistake to order Kirk Hunter's Sapphire. As soon as I tried the samples I knew I should have bought Emerald from him. Now I have both because I just had to get Emerald.
I am very happy with it. The only complaint I have that it is huge, and while the instructions comes with the 4 DVDs, they are dipersed in the samples as text files. It would be better to keep them in one printable file because for a while you will have to look up things often if you wish to use the great number of articulations efficiently. I am making my 'manual" now. Kirk said at one point on this Forum that he did not intended this to compete with the "big ones". Maybe not, but what I experienced with Sapphire and Emerald, I did not hear or experience with the Big Ones.
Kudos and success to Kirk.
