Dave Smith Instruments Poly Evolver PE Keyboard Synthesizer  

Features

• Each voice is a complete Evolver with four oscillators per voice (two analog and two digital).
• True stereo signal path with separate Curtis analog low-pass filters in each channel for each voice. Each voice has its own independent effects (feedback, delay, distortion, high-pass filter, etc.).
• Highly accessible sound control for easy, intuitive operation: 78 knobs and 58 switches.
• Clocked, pulsing blue LEDs and hardwood end-panels.
• Each voice has an independent 16 x 4 step sequencer. Everything (sequencer, LFOs, and delay) syncs perfectly to MIDI.
• In Program mode, all four voices play the same sound. In Combo mode, voices can be allocated however desired: stack all 4 for a huge unison sound, split or layer the keyboard in any configuration, and/or play one or all sequences at the same time. Each voice can respond to a different MIDI channel.
• Each voice has its own stereo output in addition to the mix and headphones outputs.
• Stereo audio input that can be routed to any or all of the voices, enabling parallel audio processing of external stereo or mono signals. The output of one voice can be routed to the input of another for interesting double-processing effects.
• 5-octave, semi-weighted keyboard action with velocity and aftertouch
• Spring-loaded pitch wheel and assignable mod wheel
• 512 fully editable Programs (4 banks of 128) and 384 Combos (3 banks of 128)
• Numeric keypad for direct access of Programs and Combos
• Oscillators per voice: 2 digitally controlled analog oscillators (DCOs) with selectable sawtooth, triangle, saw/triangle mix, and pulse waves (with pulse-width modulation), and hard sync; 2 digital wavetable oscillators with Prophet VS waves and wave sequencing capability, FM and ring modulation
• White noise generator
• 2 low-pass filters per voice: 1 analog Curtis filter per channel, selectable 2- and 4-pole operation (self-resonating in 4-pole mode)
• 3 Envelope Generators per voice: filter, VCA, and assignable (four-stage ADSR).
• 4 LFOs per voice
• Glide (portamento): separate rates per oscillator
• Analog VCAs
• Digital high-pass filter
• Digital delays: 3 separate, syncable, stereo delay lines per voice
• Tuned feedback with "Grunge": use feedback as a pitched sound source
• Distortion and "Output Hack"
• 16 x 4 step sequencer per voice
• Power supply: for 110V - 240V AC operation (15 VDC, 1300 mA)
• Dimensions: 5.09" H (2.84" at front edge, and the keyboard's feet account for 0.625" of the total height) x 14" W x 38-1/2" D
• Weight: approximately 28 lb.
• Ins and outs:
• MIDI In, Out, Thru, and Poly Chain
• Stereo audio input: 1/4" unbalanced
• Main stereo audio output: 1/4" unbalanced
• Separate stereo outputs (per voice): 1/4" unbalanced
• Sustain pedal input: accepts normally on or normally off momentary footswitch
• Pedal/CV1 and Pedal/CV2 inputs: responds to expression pedals or control voltages ranging from 0 to 5 VDC (protected against higher or negative voltages)
• Headphone output: 1/4" stereo phone jack
