Congrats man...sounds amazing. I think AcousticSamples did something like this just recently as well. The product is called Vtines. I'm a bit confused as to how all of this works though. So it's not a sample based product, rather all Math I'm guessing. So you convert a Rhodes from a series of sine waves, similar to a wavetable, but mathmatics is making the sound, instead of a sample....
Pretty ingenious idea....We've been working on something similar with wavetables.
