The Evolver Keyboard has a 3 octave keyboard, with velocity and aftertouch (pressure). There are 58 endless-turn knobs, and 35 switches. It measures 26" wide, 12" deep, and 3" high, and weighs 13 pounds.
The Desktop Evolvers have an easy-to-program matrix-style front panel with 8 endless-turn rotary encoders. It is 10.75" wide, 6" deep, and 1.5" high (27 x 15 x 4 cm), and weighs about 3 pounds. Yes, it is small!
The Evolvers universal power supply runs virtually anywhere; 100 - 240 V AC, 50-60 Hz. It also includes 4 adaptors: USA, Euro, UK, and Australia.
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, with two glide modes
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
4 Banks of 128 Programs for 512 total Programs - dump to/from MIDI
16 x 4 Analog-style sequencer - syncs with MIDI
Extensive Modulation capabilities, including audio-range modulation. Bipolar (+/-) modulation.
A bunch of MIDI stuff
The internal computer and DSP chips can be reprogrammed via MIDI, for easy feature additions
The new stand-alone editor for the PC is now available, as is the Mac OSX version!
This editor is perfect for users who want to use their PC to generate sounds for Evolver. Packed with all the features you would expect, and then some, it allows you to see all the parameters in one concise screen, a great way to analyze those complex factory programs.
Other screens allow wavetable editing, bank views, main parameter views, and a very cool random program generator that includes some interesting genetic program generators. There are two different views for the sequences also.
