Oscillators Continuously variable wave shape (triangle, sawtooth, pulse, square) per oscillator Pulse width per oscillator Hard sync: oscillator 1 syncs to oscillator 2 Triangle sub-octave generator (oscillator 1) per voice Low frequency mode (oscillator 2) Keyboard tracking on/off (oscillator 2) Oscillator slop amount for increased tuning instability, from subtle to extreme Mixer Oscillator 1 amount Oscillator 1 sub-octave amount Oscillator 2 amount White noise amount High-pass filter 2-pole, resonant, high-pass filter per voice Bi-polar filter envelope amount Velocity modulation of envelope amount Keyboard tracking: off, half, full low-pass filter Four-pole, resonant, low-pass filter per voice, inspired by the original Prophet-5 filter Filter can be driven into self-oscillation with the Resonance control Bi-polar filter envelope amount Velocity modulation of envelope amount Keyboard tracking: off, half, full poly mod Sources: filter envelope (bi-polar) and oscillator 2 (bi-polar) Destinations: oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, low-pass filter cutoff, high-pass filter cutoff effects Stereo analog distortion Dual, 24-bit, 48 kHz digital effects, including: reverb (room, hall, plate, spring), delay (full bandwidth digital delay and emulated bucket brigade and tape delays), chorus, and phase shifter Delay sync True bypass maintains fully analog signal path when digital effects are off sequencer Polyphonic step sequencer with up to 64 steps and rests patch memory 500 user and 500 factory programs in 10 banks of 100 programs each Direct program access, including Prophet-5 style single-button access to the current set of 10 programs performance controls Full-sized, semi-weighted, 4-octave keyboard with velocity and aftertouch Backlit pitch and mod wheels Spring-loaded pitch wheel with selectable range per program (1 to 12 semitones up and down) Transpose controls for an 8-octave range Hold switch latches held notes on Polyphonic glide (portamento) Unison (monophonic) mode with configurable voice count, from one to all six voices, and key modes Preset switch: when off, the front panel is live; what you see is what you hear
