Dave Smith Instruments Poly Evolver Rack Analog / Digital Synthesizer Module

Poly Evolver Rack Analog / Digital Synthesizer Module description:

The Dave Smith Instruments Poly Evolver Rack is essentially four Evolvers in a single rack space. It can be a four-voice poly synth, four mono synths (each with its own sequencer!), or any combination in between.

The Dave Smith Instruments Poly Evolver Rack features 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 also respond to a different MIDI channel.

Multiple Poly Evolvers can be daisy-chained for increased polyphony, with built-in audio chaining for simplicity. “Poly Chain” mode handles voice assignment overflow for easy expansion to 8, 12 or even 16 voices.

Dave Smith Instruments Poly Evolver Rack main features include:

• Four Evolvers in a single rack space
• Each voice is a complete Evolver with four oscillators per voice, two analog and two digital
• 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 jacks in addition to the mix output
• 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
• Includes the Soundtower editor/librarian for both Windows and Mac OS X
• 512 fully editable Programs (4 banks of 128) and 384 Combos (3 banks of 128)
• Oscillators: 2 digitally controlled analog oscillators (DCOs) per voice 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: 1 analog Curtis filter per channel, selectable 2- and 4-pole operation (self-resonating in 4-pole mode).
• 3 Envelope Generators: filter, VCA, and assignable (four-stage ADSR).
• 4 LFOs.
• Glide (portamento): separate rates per oscillator.
• Analog VCAs.
• Digital high-pass filter.
• 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.
• Headphone output: 1/4" stereo phone jack.
• Includes power supply for 110V – 240V AC operation (15 VDC, 1300 mA), operation manual, license for Soundtower editor/librarian for Windows and Mac OS X.
