The sound is absolutely excellent, it just stomps. I own two mono evolvers so I thought I knew what I was getting, but for some reason, the polyevolver sounds even better; I don't know why. It's alive and organic in a way most other modern synths aren't; if you're just a bit disappointed how your VA sounds, this might cure you. I bought this instead of an Andromeda, and although the A6 is excellent (and can do some things the evolver probably can't, and has a lot more polyphony), but to my ears the PEK just sounds better.

The PEK build is top-notch, the semi-weighted keyboard (same as A6) is great and very playable, the controls feel good, the design very classy (real hardwood ends).

Probably the only real downside for most people is the limited 4-voice polyphony. You can hook up more evolvers to increase the polyphony; I have have two, but haven't tested that function yet.

[A small but annoying thing is that the PEK follows the recent trend and uses some blue LEDs as indicators -- and they're _way_ too bright; I don't need my eyes seared from their sockets every time I look at the front panel, thankyouverymuch... It also uses illuminated mod/pitch wheels which I find quite distracting, and there's no way to turn off the illumination.]
