Amethyste,
Congrats! Major achievement. I can't wait to get it (I saw your "teaser"). I think a thread on your experience would be really instructive. What you had to do get the sound the way you wanted it. What had to be done to the sound. You are leading the way here for a lot of us. Personally I really want to know how you get such a nice sound - both the theremin and piano. They don't come out of the box that way!
I need all the tips I can get.
