I wasn't too keen on the idea at first, but as more instruments have been revived by different companies, the notion of re-issues has become very appealing. My only qualifier is that they should have a few modern improvements - most importantly, an increase in the number of voices, and in the case of vintage instruments, MIDI. Aside from that, the immediacy of the older instruments is so refreshing. Their emphasis on the fundamentals of synthesis, to the neglect of other features that are common today, is actually a strength, in my opinion. Now I'm every bit as interested in re-issues as in new designs.
I would be extremely interested in a Poly Evolver Keyboard Rev2, presuming it had at least eight voices. And I would commit to buying one immediately, since, after so many other brilliant creations, it still strikes me Dave's masterpiece.
