These are sounding great guys. Thats alot of great effort you are putting in. Excellent work.
I cant remember where I seen it, but I seen a program that takes on voice, and makes it into a sorround sound choir. I think with your many voices you have you could have a full sounding choir. It may broaden your samples a bit. I need to hunt it out.
These choir sustains are nice. However have you ever thought abouting a staccato patch? There's already alot of sustain samples out there, but amazing staccato patches are hard to find/afford. Oh, and how hard is it to make these into Kontakt from your wav samples, i've always wanted to make kontakt packs to make it easier on myself.
Great work all around, cant wait for a play around!
