Polyevolver sounds cool for bells and chimes. I also like SQ-80 and MW I in that department. Still we have one little difference in here - dynamic vectors. Without them, VS emulation is a bit difficult and i know a lot of the "trademark" VS sounds are made using two dimensional vectoring.
We should also keep in mind that Prophet VS has 32 digital oscillators, while Polyevolver 8 of them. A lot of the VS magic lies in patches made with 4 oscillators (often identical but detuned). Greater difference of course once you hit unison or start layering larger chord structures.
IMO both are great synths! I also like Korg Wavestation A/D. Probably my favorite digital ever, along with the Waldorf XT.
Yes, vectoring can be EXTREMELY fast, so you can use it make your own attack transients. On the Wavestation this is not possible, the vector envelopes are too slow.
Slow vectors in dual unison blow the Wavestation out of the water as well.
The SQ-80 has the grunge and the filter, but no movement, and no unison.
The 32 oscillators used in unison or dual unison is where it shines, the most classic VS patches are made this way.
If I lost my VS somehow, the Microwave series would be the closest to that sound.
