Specs

Voltage Controlled Oscillator 1, 2, 3
Wide audio range (64’-2’) w. Tune & Fine; six analog waveforms (sine, triangle, triangle & saw, saw, saw & variable pulse summed, variable pulse); manual pw & pwm (from VCLFO1, EG1, S&H, Aft); FM 1 Amt (lin/exp –from VCLFO1, LFO2, VCO1, 2, 3, Noise, S&H, EG1, EG2, Aft, ModW, KeyVel, EnvFoll) w. phase rev; FM 2 Amt (only exp – from VCLFO1, Env Foll); sub oscillator (on VCO 1, 2) -1/-2 oct; hard sync (VCO 1 master); kybd on/off (w. user’s selectable octave offset from MIDI Interface).

Ring Modulator
Ring Mod Sources: VCO 2 & VCO 3/Ext Input (user’s selectable).

Noise Generator
White & Pink Noise selectable.

External Input
Input gain from line to mic level; freely adjustable Gate Threshold (Gate to EG 1-2); enclosed envelope follower (goes into mod buss).

Audio Mixer
Separate level controls for VCO 1, 2, 3, Sub 1, 2, Ext Input, Ring Mod, Noise.

Filter Section
Dual analog filter section: 24 db/Oct Low Pass Transistor Ladder Filter w. pole selection & 12 dB/Oct State Variable Low, Band, High, Notch Filter.
Each filter has a separate Distortion/Level control.
Filter section can be configured in LP 24 Only, SV 12Only, Serial (LP into SV), Parallel, Direct Out (LP 24 goes on Left Audio Out, SV 12 goes on Right Audio Out).
Low Pass Filter:
Slope selection (6, 12, 18, 24 dB); Cutoff Frequency; Resonance; Overload LED; FM1 Amt (from VCLFO1, LFO2, VCO 1, 2, 3 Env Foll, Noise, S&H, EG2, Aft, ModW, KeyVel) w, phase rev.; FM 2 Amt (from VCLFO 1); FM 3 Amt (from Step Sequencer, Kybd Track 0-120%; Key Vel On/Off.
State Variable Filter:
Mode (12dB HP, 6 dB BP, 12 dB LP, 6 dB Notch); Cutoff Frequency; Resonance; Overload LED; FM1 Amt (from VCLFO1, LFO2, VCO 1, 2, 3 Env Foll, Noise, S&H, EG2, Aft, ModW, KeyVel) w, phase rev.; FM 2 Amt (from VCLFO 1); FM 3 Amt (from Step Sequencer, Kybd Track 0-120%; Key Vel On/Off.

Voltage Controlled Amplifier
Dedicaded Envelope Generator (see below); Control Selection (dedicated EG2, ON-hold, External CV); VCLFO1 Amt.

AutoPan
AutoPan Off/Internal Clock/VCLFO1; Pan Frequency Control; LED (red = internal clock; blue = VCLFO1).

Stereo Main
Master Volume.

Envelope Generator 1
Multi Stage Loopable Env (Attack, Hold, Decay, Sustain Lev, Sustain Time-Only in Loop On, Release); Gate Source Selection (Keyboard, S&H, ExtIn/ Step Seq); independent EG Amt for 24 dB LP Filter and 12 dB State Variable Filter, both w. user’s selectable EG polarity.
EG time goes from 1msec to 20 sec.
LED: red = EG under Gate sources; blue = EG under Step Sequencer control;
Loop Envelope: loop from Attack to Release, w. Sustain Time selectable.
Loop Mode Switch:
Loop Off: EG as standard AHDSR, no Sustain Time.
Gate: EG loops from A to S (w. Sustain Time max 60”) as long as Gate is On.
Auto: EG full loop, from A to R; independent from Gate.

Envelope Generator 2
Same as EG 1, without Hold segment.

Voltage Controlled Low Frequency 1
Frequency (from very low to 2500 Hz); Waveform (sine, ramp, triangle, saw, square w. variable pulse); FM Amt (exp, w. phase normal/rev); FM Sources (Key, EG1, EG2, LFO2, Seq A, B, A+B, S&H, Aft, ModW, EnvFoll); Sync (Off, Gate, Seq, MIDI – dividing factor selectable from internal MIDI Interface); Shaping LFO out (from: Off, EG1, EG2, Lfo2, SeqA, B, A+B, S&H, Aft, ModW, EnvFoll).
LFO act as modulation buss for auxiliary sources: EG1, EG2, S&H, Noise, VCO2, EnvFoll. The aux source can be amplitude modulated with the Shaping Select.

Voltage Controlled Low Frequency 2
Frequency; Freq Range (Low-Mid-High); Waveform (Triangle, Square); Shaping Select (Off, Aft, ModW).
Independent Send Modulations for: VCO 1, 2, 3 freq; PWM 1, 2, 3; VCF 24/12 Cutoff; VCA Level.
