This is the 61-key keyboard version of Dave Smith Instruments PK4 Poly Evolver synth with a one-button-per-function layout. Controls include 78 knobs, 58 switches, backlit wheels, and blinking LFO and blue sequence LEDs. As in the rack version, each voice has 2 analog and 2 digital oscillators. The analog oscillators offer multiple waveshapes with voltage-controlled analog pulse-width modulation, hard syncing, real voltage-controlled lowpass filters, and VCAs on each channel. The digital oscillators select from 96 Prophet-VS and 32 user-loadable (via MIDI) wavetables and have FM and ring modulators. As with original VS, the digital oscillators get trashy as the frequency gets higher.
Other tools and features include a separate glide per oscillator, dual digital 4-pole highpass filters that can be placed before or after the analog electronics, stereo audio inputs, a noise generator, envelope follower and peak detect from the external input for use as a modulation source, 3 snappy ADSRs, and 4 LFOs that are sequencer- and MIDI-syncable.
Additional features of this synth include dual tunable feedback loops, delay with 3 taps, digital distortion, 3 banks of 128 programs for 384 total, a 16 x 4 analog-style sequencer that syncs with MIDI, and extensive modulation options.
Dave Smith Instruments includes a free standalone editor with the PK4 Poly Evolverthat will run on both a PC and a Mac enabling you to edit both programs and combos quickly and easily.

this is the perfect synth. does both real analog and extreme digital. I have never been so happy with an instrument. it is just so insipiring. some trivia. Wolfgang Matthes used this almost exclusively for the electronic music in the movie Dawn of the dead.
Excellent synth, the other reviewers keep comparing it to Moog... get a life, so you like Moog. This is more Prophet-like sound, 2 analog and 2 digital oscillators, cool sequencer. Like Moog? Stick with Moog. I like Polyevolver:)PS: It does sound very good, go to your local store and try it!
I already own a Voyager and an Evolver, but was quite stoked to get the PEK (Dave Smith Poly Evolver Keyboard). I chained my Evolver to the PEK to get a five-voice instrument. (It took me a while to figure this out - I had to upgrade my Evolver first, but the folks at DSI were friendly and helpful. I even got help from Dave!) Dave Smith has pushed the hardware envelope with this keyboard - it has a huge amount of character and individuality for only 16 oscillators. Most of the controls are on the board (not buried in menus) for quick editing and tweaking. It has more modulation capability than I expected. And the sound: Take a Prophet 5 and add grit, dirt, and lots of dynamics (meaning sounds that can continue to change over time) and throw in an amazing light show to boot. The voice assignment architecture is brilliantly implemented and allows all voices to be assigned to a single patch, or each voice to do its own thing, complete with a sixteen-event sequencer per voice.
I played this thing the other day. Yeah it is analog but it isn't very good compared to moog's analog synths like the voyager or any other modls or vintage models. Yeah it has allot of features but everything on it seemed cheap and and it a had a knob or two broken off of it. Odviously It is a good synth but not for the price and it is cool that it is analog but if your going to spend that kind of money I would bu a moog.
I had an opportunity to play with this thing for about 2 hours at Guitar Center. It sounds great, not like MOOG but great in it' own way. It has a very deep and thick sound. It's also very flexible. If you can handle the 4-voice limitation (more if you add more units and chain them), then it's good choice at a good price point. The built in analog-style sequencer is great, and the sound that come out of this thing are fantastic. It would take months to if not years to understand the full potential of this thing. It will become a classic, as are all instruments that are built by Dave Smith.... that's for sure.
