This is a version of 'Plated Cello' from the Reason Factory Sound Bank. I added breath control to the NN-XT cello patch. I think it came out pretty good. I originally thought I would create my own combinator, but I liked the setup of the stock patch from the Factory Sound Bank. It has controls for reverb, chorus and a bass boost. I'd use it on a gig.
I've included an mp3 demo of this patch. Hope you like it!
