I wish you the best of luck Pat, the idea of using autotune first is a good idea too. As I was trying to point out earlier, the guy you spoke to on the phone about the human voice, more or less said the same thing in different words.

I will be interested in hearing how you get on with it and if possible a video, or even just a sound track, as I have had quite an interest in sound production and reproduction for a very long time.
