Multimode Filtermultimode-filter
4-stage cascaded OTA filter with dedicated LP (24dB/oct), BP (12dB/oct), and HP (24dB/oct) outputs plus a MULTI output with 27 selectable filter types across LP, BP, HP, Notch, AP, and Phaser modes.820
Phaserphaser
PHASER mode on the MULTI output blends all-passed signal with original input to create phaser effect; can be modulated via FM inputs.820

NameSignalVoltageDescription
Inputs (4)
FM1cv—CV input for cutoff frequency modulation. Attenuation controlled by FM1 knob; tracks 1 V/octave when knob is fully CW.820
FM2cv—CV input for cutoff frequency modulation with polarizer control. Polarity and amount controlled by FM2 knob.820
INaudio—Audio input to the filter.820
Qcv—CV input for the Q (resonance) control. Amount is attenuated by the Q Attenuator knob.820
Outputs (4)
BPaudio—2-pole (12 dB/oct) band pass filter output.820
HPaudio—4-pole (24 dB/oct) high pass filter output.820
LPaudio—4-pole (24 dB/oct) low pass filter output.820
MULTIaudio—Configurable filter output with 27 selectable modes, configured by MODE and TYPE buttons. Can be processed through optional asymmetric distortion circuit.820

Parameters 9

NameTypeRangeBehavior
CUTOFFknob—Sets the cutoff frequency of the filter. The knob position is combined with the FM1 and FM2 CV inputs.820
FM1knob—Controls attenuation of the FM1 CV input for cutoff frequency modulation. Tracks 1 V/octave when fully clockwise.820
FM2knob—Controls amount and polarity of FM2 CV input for cutoff frequency modulation. Fully CW passes unmodified; fully CCW inverts; 12 o'clock has no effect.820
Zones
Inverted
Normal
  • Inverted -100–0%FM2 input is inverted and attenuated, with full inversion at fully CCW and no effect at noon.820
  • Normal 0–100%FM2 input attenuated toward zero at noon, passing unmodified at fully CW.820
INPUT DRIVEknob—Sets the drive/amplification of the input signal. Unity gain at 12 o'clock; at higher settings the signal experiences soft clipped distortion.820
MODEbutton—Cycles between LP, BP, HP, N (Notch), AP (All pass), and PHASER modes for the MULTI output. LEDs below the button indicate the current mode. The PHASER setting blends the all-passed signal with the original input.820
MULTI DISTORTswitch—When in the up position, engages the asymmetric distortion circuit on the MULTI output.820
Qknob—Sets the resonance of the filter. Combined with the Q CV input (attenuated by the Q Attenuator knob).820
Q Attenuatorknob—Attenuates the Q CV input signal before it is summed with the Q knob position.820
TYPEbutton—Cycles between filter type variations (A through D or E) for the currently selected MODE. Each mode has up to 5 variations with increasing filter slopes. The module remembers the last selected type for each mode at power down.820
