Certainly. It was called the 'VDP' decoder, 'Variable Directional Preference'. Michael and I had great fun with that; it revealed all sorts of detail in stereo recordings played through it, quite apart from the effect on UHJ. I believe that, some time after I left the Cybernetics dept, to quote Peter Fellgett, 'a student destroyed it by connecting 240v into the 5v supply'. rgds, Geoffrey _______________________________________________ Sursound mailing list [email protected] https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
