OSCILLATORS
Two newly designed, discrete VCOs per voice
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 sub-octave amount
Oscillator 2 amount
White noise amount
HIGH-PASS FILTER
Two-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

LOW FREQUENCY OSCILLATOR
Five wave shapes: triangle, sawtooth, reverse sawtooth, square, and random (sample and hold)
Clock sync (internal or external MIDI clock)
Initial amount
Mod destinations: oscillator 1 frequency, oscillator 2 frequency, oscillator 1 and 2 pulse width, low-pass filter cutoff, high-pass filter cutoff
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
AFTERTOUCH
Source: channel (mono) aftertouch with bi-polar amount
Destinations: oscillator 1 frequency, oscillator 2 frequency, LFO amount, amplifier envelope amount, low-pass filter envelope amount, high-pass filter envelope amount
CLOCK
Master clock with tap tempo
BPM control and display
MIDI clock sync
ARPEGGIATOR
Selectable note value: 16th note, 8th note triplet, 8th note, dotted 8th note, quarter note
One, two, or three octave range
Up, down, up/down, random, and assign modes
SEQUENCER
Polyphonic step sequencer with up to 64 steps and rests
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
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
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
IN/OUT
Left/mono and right audio outputs (2 x 1/4” phone jack)
Headphone output (stereo, 1/4” phone jack)
MIDI in, out, and thru ports
USB for bidirectional MIDI communication
Low-pass filter cutoff expression pedal input
Volume expression pedal input
Sustain footswitch input
Sequencer start/stop footswitch input
