I've got a TG33. To be honest, it's been kind of ignored lately; I've been busy thrashing a V-Synth and a Morpheus and trying to repair a Fizmo... too many new arrivals at one time. The little bit that I've played with it has been fairly interesting, although the actual vector stuff that I've tried so far has come out sounding like ordinary cross-fading rather than morphing. To me, the main limitation is that the FM channels are only two-operator. The way that Yamaha implements FM, that isn't very useful. 4-op would have been a lot better.
Switches, knobs, buttons, LEDs, LCD screens, monitors, keys, mice, jacks, sockets. Now two joysticks!
