This Pedal is discontinued.
The Evolver’s unique tonality comes from the synergy of its two analog oscillators and two digital oscillators (which feature the waves from the legendary Prophet VS). Classic Curtis analog low-pass filters and real analog VCAs add warmth and girth to the analog section while the digital high-pass filter, tuned feedback, and digital distortion provide sizzle and grit. But what really sets the Evolver apart is the way in which the analog and digital sides of its personality mesh—in a true stereo signal path. Massive doesn’t even begin to describe the sound of the Evolver.
Monstrous four-oscillator voice architecture
True stereo signal path with separate Curtis analog low-pass filters in each channel
Dedicated onboard effects (feedback, delay, distortion, high-pass filter, etc.)
16 x 4 step sequencer really brings the Evolver to life with evolving “pseudo-polyphonic” sounds – you won’t believe it’s mono!
Stereo audio input for audio processing of external stereo or mono signals, enabling the synth to act as a unique stereo effects processor
Everything (sequencer, LFOs, and delay) syncs perfectly to MIDI.
Easy-to-navigate matrix-style interface for quick editing and real-time control of 8 parameters simultaneously
Multiple Evolvers can be daisy-chained for more polyphony.
OSCILLATORS
Two digitally controlled analog oscillators (DCOs) with selectable sawtooth, triangle, saw/triangle mix, and pulse waves (with pulse-width modulation), and hard sync
Two digital wavetable oscillators with Prophet VS waves and wave sequencing capability, FM and ring modulation.
White noise generator.
FILTERS
One low-pass analog Curtis filter per channel, selectable 2- and 4-pole operation (self-resonating in 4-pole mode)
Digital high-pass filter
ENVELOPES
Three Delay + ADSR envelopes: filter, VCA, and Auxiliary envelope
Envelopes freely assignable to multiple modulation destinations
All envelopes can repeat/loop

Four syncable LFOs
Glide (portamento): separate rates per oscillator.
512 fully editable programs (four banks of 128)
MODULATION
4 x 2 modulation matrix with 24 mod sources and over 75 mod destinations
FEEDBACK AND DELAY
Tuned feedback
Three-tap syncable delays with feedback and amount controls per delay
