I love your approach and I do want to become a user and supporter. I may still get a unit in its present form since all future enhancements will be add-on-able or at least that's the plan.
I've been thinking about the vocoder/vocal cavity idea for some time now and believe it has great possibilities. I would definitely make some cool noise with that. Sounds that I attempt to make today with a wah pedal could be made richer with the mouth while playing. I even considered using a talk box while playing. I like how you guys are thinking outside the box and I understand that it takes time.
