The article referenced by Kwaidan states that Roland founder Mr Kakehashi said “It wasn’t until now that he felt ready to put this name on an instrument again”. I was always under the impression, as others have suggested, that Roland no longer had the rights to the ‘Jupiter’ name or it would have been on the JP-8000. Indeed, the JP-8000 would have been a more credible bearer of the ‘Jupiter’ name.
I’ve no doubt that the Jupiter-80 will do what it does brilliantly, but what it does, does not identify it as a ‘Jupiter’. To my mind it’s another ‘jack-of-all-trades’ workstation (less sequencer), not a master of pure synthesis like the Jupiter 8 was. The name ‘Jupiter-80’, for me, conjures up images of a pure synth for the 21st century which combines analogue oscillators with modern technology for the purest sound combined with the greatest flexibility and stability. What we actually have is another generic pub-singer’s backing keyboard, albeit a very good one.
