I agree with everything you've said, A Thousand Eyes. I only tossed out the workstation idea as a possibility, a mere guess, and not one that personally interests me. I don't think it's at all likely. But...Dave does surpise us at times.
To anyone who's followed this forum for some time, it would be difficult not to notice the many requests that have been made over the years for a new Wavestation/VS/Poly Evolver type of instrument. It's been a steady drum beat for quite a while. So many people from so many different musical perspectives have wished for this. (Considering the age of my PEK/PER pair, it's my wish, too.) The Sequential staff knows it, and so Dave must know it as well. But we can only hope for another unexpected surprise.
Nothing sounds like an Evolver. I listen to the videos of the new exciting feature-rich poly synths as they come out. I've watched the Peak and Summit demonstrations. Nice lovely impressive instruments, one after another; but still, nothing sounds like an Evolver, not even a Prophet 12 or a Prophet X. I had thought the latter might, but no. So, the Evolver is worth reviving, among other reasons, because in a crowd of poly synths its sonic character still stands out. It may be related to the stereo filters, or the stereo oscillators, or even the very long envelope times that allow you to achieve a deep dreaminess. But the Evolver's unique sound definitely has to do with the specific selection of digital oscillators. These were allegedly designed in a rather haphazard arbitrary way, but the results were memorable. The tones, combined with the analog oscillators, make the distinctive voice of the Evolver. Perhaps they might need to be cleaned up a bit - although the aliasing is also an important quality to the Evolver's voice - but they are the heart of the big blue monster.
