AUX 1 amountfader641
AUX 1 Source Switchswitch641
AUX 2 amountfader641
AUX 2 ROUTING switchswitchMIX position: AUX 2 is mixed pre-VCF with other MIXER signals. VCA position: AUX 2 bypasses the VCF and feeds directly to the VCA.641
AUX 2 Source Switchswitch641
D (DECAY Time)fader641
DRIVE switchswitchSYM (top): symmetric clipping/drive; X (middle): no drive; ASYM (bottom): asymmetric clipping/drive.641
ENV Polarity switchswitch641
ENV/GATE switchswitch641
ENVELOPE RATEswitchFAST: A max ~1.5-2s, D/R max ~7-8s. MED: A max ~10-12s, D/R max ~35-40s. SLOW: A max ~19-21s, D/R max ~70-75s.641
FM 2 amountfaderControls exponential FM depth from FM 2 IN. Top = maximum FM; bottom = no FM.641
FM 2 Polarity switchswitch641
FREQmenu_setting641
HOLD SOURCE switchswitchSelects the normal for S&H HOLD input: GATE (right) = gate signal; S&H (up) = traditional S&H mode from external; VCO B SQUARE (left) = VCO B square wave. Also selects T&H (down) = track-and-hold mode.641
IM sliderfaderAttenuates the CV signal at the IM IN jack before it modulates the FM INDEX. At top, maximum modulation; at bottom, no modulation.641
INDEXfaderSets the base FM INDEX level — the amount that a signal at FM A IN modulates VCO A frequency. At highest position, FM is maximum; at bottom, no FM occurs.641
LP/BP/HP switchswitchSelects between LP (lowpass), BP (bandpass), and HP (highpass) filter types. HP is always 4-pole; LP and BP can be 2-pole or 4-pole via the 4P/2P switch.641
MANUAL GATEbutton641
MOD X POLARITYswitch641
MOD X Sourceknob8-position rotary: selects from VCO B Sine, Triangle, Saw, Square; S&H; Noise; VCF; VCA. Output normalled to VCO A FM A input.641

MOD Y POLARITYswitch641
MOD Y Sourceknob8-position rotary: selects from VCO B Sine, Triangle, Saw, Square; S&H; Noise; VCF; MIX. Output normalled to VCF FM A input.641
MOD Y UNIPOLARswitch641
NOISE amountfader641
NOISE TYPEswitch641
OCTAVE Aknob8-position selector that sets the coarse tuning of VCO A. Each clockwise rotation shifts the tuning up by one octave.641

PHZ/Filter switchswitch641
PITCH Aknob641
PITCH Bknob641
PITCH SOURCEswitchA+B (up): VCO B tracks sum of PITCH A and PITCH B inputs; B (down): VCO B tracks only PITCH B input.641
PULSE amountfader641
PULSE POSITIONswitchUp = center-triggered pulse; down = edge-triggered pulse. Both are essentially the same waveform but with different phase relationships affecting how they blend or sync with other waveforms.641
PWfader50% – 95%Sets the pulse width of VCO A PULSE wave. At bottom = 50% duty cycle (square wave); at top = ~95% duty cycle (thin pulse). 100% can be reached with PWM CV, which silences the output.641
PWM sliderfaderAttenuates the CV arriving at PWM IN. At top, maximum PWM; at bottom, no modulation.641

SAW amountfader641
SUB amountfader641
SUB TYPEswitchSUB -1 (left): square wave 1 octave below VCO A. SUB -2 (right): square wave 2 octaves below VCO A. OR (center): logical OR of SUB -1 and SUB -2, giving a pulse wave 2 octaves below VCO A with 75% pulse width.641
SYNC A SOURCEswitch641
SYNC TYPEswitchLeft = Hard Sync (resets VCO A waveform at each positive zero-crossing of sync source); center = No Sync; right = Soft Sync (flips VCO A waveform at positive zero-crossing of sync source).641

VCF FM 1 Amountfader641
VCF FM 2 Amountfader641
VCO/LFO switchswitchVCO (left) = audio rate; LFO (right) = 1/1000 of VCO frequency, allowing cycles as slow as approximately 50 seconds.641
