Like this interview from 1977.
How do you feel about the prototype Polymoog that you have?Hopefully Patrick has returned it by now.
Well, I don’t really like it that much. I don’t use it anymore. You know, I helped design that. I spent about a week with Dave Luce in the studio. While I was there I was saying, "It’s good, but it could be better if you did this and this, and added this to it." So he made some notes and then went back to Buffalo and had the second prototype made up. When I went to Buffalo, I tried it again. All the bumps were out and I said, “Well, it could be good if you had the knobs in this position." So he made some more notes, followed those ideas through, and the next thing I’m expecting is to see the end result. You’d think that after working on the instrument I’d get to see it. But the next thing I know, they’ve sent it to Switzerland. I won’t say to
whom. Well, I was a bit upset."
