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.
