Evolver is a monophonic (one voice) synthesizer

Technical specifications

Four oscillators in total: two analog, two digital

Analog Oscillator waveshape are Sawtooth, Triangle, Saw-Triangle, and Pulse (with voltage-controlled analog Pulse-Width modulation)

Digital Oscillators select from 96 wavetables from the Prophet-VS (128 x 12 bits), and 32 user-loadable (via MIDI) Wavetables (128 x 16 bits). The Digital Oscillators get trashy as the frequency gets higher, as with the original VS.

Hard Sync on the analog oscillators

FM and Ring Mod on the digital oscillators

Separate Glide per oscillator

Real voltage-controlled analog lowpass filters - not digital recreations. 4-pole/2-pole switchable, fully resonant (in 4-pole mode). There are two separate filters, one for the left channel and one for the right.

Analog Voltage Controlled Amplifiers (VCA), again one for each channel.

Dual digital 4-pole Highpass filters (one per channel); place before or after analog electronics.

Stereo audio inputs; Noise generator

Envelope Follower and Peak Detect from External Input to use as modulation sources

External Input can be used to gate envelopes and/or step the Sequencer

Three snappy ADSR envelopes

Four LFOs (sync with sequencer and MIDI)

Dual (left and right channel) tunable feedback loops; modulate frequency and amount

Delay with 3 taps; each with separate time and amount modulation. Syncs to sequencer/MIDI. Normal feedback and additional feedback path through analog filters

Distortion! Digital, one for each channel, can be placed before or after analog electronics

3 Banks of 128 Programs for 384 total Programs - dump to/from MIDI

16 x 4 Analog-style sequencer - syncs with MIDI

Extensive Modulation capabilities, including audio-range modulation. Bipolar (+/-) modulation.

Easy to program matrix-style front panel with 8 endless-turn rotary encoders

A bunch of MIDI stuff

The internal computer and DSP chips can be reprogrammed via MIDI, for easy feature additions

Evolver is 10.75" wide, 6" deep, and 1.5" high (27 x 15 x 4 cm).
