"Tristram Cary: Yes, that's right, and that's the master patch on the pin matrix of the VCS3. I mean we designed the VCS3, three of us in 1967 in direct competition with Bob Moag [sic, Moog], who was, poor chap's dead now, he had cancer, ten years younger than me. But we went over and saw Bob Moag [sic, Moog], I mean he was a great friend a very nice man. But his synthesizers were very expensive in England, so we said Well, we can - and I'll tell you what, there's a very interesting connection here because Don Banks, who was a good friend of mine in London, and I knew Don for 20 years before poor chap died of leukaemia [sic], he was doing films and stuff like me, and he came and saw us over in Putney, and said, Look, I'd love to get into electronic music, but I haven't got any knowledge, I can't build anything, can you make me something? My limit is 50 pounds, he said, can you make for 50 pounds a box of some sort which would be useful to a composer. So we got together, and we put it together, David put it together, and he was delighted. Don started using it straight away."
