The Mono Evolver Keyboard combines the classic monophonic Evolver desktop engine with a 37-key keyboard and knobby interface.

Features

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