Dave Smith Instruments Poly Evolver Keyboard Analog / Digital Synthesizer

Poly Evolver Keyboard Analog / Digital Synthesizer description:

The Dave Smith Instruments Poly Evolver Keyboard is a four-voice synthesizer with a 5-octave keyboard, pitch and mod wheels, and a ton of knobs and switches in a clean, clear layout for the ultimate in real-time control.

Each voice of the Dave Smith Instruments Poly Evolver Keyboard is a complete Evolver with four oscillators per voice, two analog and two digital. Featuring 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.).

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.

Multiple Poly Evolvers can be daisy-chained for increased polyphony. “Poly Chain” mode (with dedicated MIDI output) handles voice assignment overflow for effortless expansion.

The Poly Evolver Keyboard features a 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.

Dave Smith Instruments Poly Evolver Keyboard main features include:

• Highly accessible sound control for easy, intuitive operation: 78 knobs and 59 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.
• Each voice has its own stereo output in addition to the mix and headphones outputs.
• 5-octave, semi-weighted action keyboard 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 per voice .
• 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 per voice.
• Digital delays: 3 separate, syncable, stereo delay lines.
• Tuned feedback with "Grunge": use feedback as a pitched sound source.
• Distortion and "Output Hack."
• 16 x 4 step sequencer.
• 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
• Stereo Mix Input: for Poly Chained Poly Evolvers.
• 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.
• Includes power supply for 110V – 240V AC operation (15 VDC, 1300 mA) and operation manual.
