Along the same route as the Kurzweil, early 90's saw the rise of FM synthesis. If your looking for industrial sounds and bell like timbres then you might like this box. With 6 operators it is a 'easy to get lost in menus' kinda synth but I houses sounds that you know and love from classic acts and bands. takes some getting into. But with everything, the journey towards succes is half the fun.
Bought new in 1992 after I had traded Yamaha DX7mkI few years before to buy a Fostex A-80 and 450, respectively reel to reel 8 track 1/4 tape recorder and 8:4:2 mixer.
With Opcode Galaxy plus Editors I succeeded converting old DX7mkI patches into TG77 ones and the better clarity of converters added a crisp to the sound I've just imagined with the former synthesizer.
