Make Noise

Four Channel Stereo Low Pass Gate and Mixer. Vactrol-free analog LPG circuit with Vactrol button for Fast/Slow response, per-channel outputs, stereo sum output with voltage-controllable Xpread, and stereo Aux input for chaining.464

Capabilities 3

Lowpass Gatelowpass-gate
Four-channel vactrol-free analog LPG circuit; CTRL sets both amplitude and frequency content. Vactrol button selects Fast or Slow response.464
Mixermixer
Four LPG channels sum to a stereo mix output; stereo Aux input allows chaining of additional sources.464
Stereo Processorstereo-processor
XPREAD parameter distributes channels across the stereo field with CV control; channels centered at 12:00, spread L-to-R or R-to-L at extremes.464

Jacks 17 — 11 in / 6 out

NameSignalVoltageDescription
Inputs (11)
Aux Left Inputaudio—Left (Mono) Aux input; mixes directly to the stereo Mix outputs. Patch only here for mono use — left input appears at both Mix outputs.464
Aux Right Inputaudio—Right Aux input; mixes directly to the stereo Mix outputs.464
CH1 Control Inputcv—CV input for channel 1 LPG circuit. Normalled to Control Inputs header (N.U.S.S.); patching breaks the normall.464
CH1 Signal Inputaudio—Signal input for channel 1 LPG circuit. Normalled to Signal Input header (N.U.S.S.); patching breaks the normall.464
CH2 Control Inputcv—CV input for channel 2 LPG circuit. Normalled to Control Inputs header (N.U.S.S.); patching breaks the normall.464
CH2 Signal Inputaudio—Signal input for channel 2 LPG circuit. Normalled to Signal Input header (N.U.S.S.); patching breaks the normall.464
CH3 Control Inputcv—CV input for channel 3 LPG circuit. Normalled to Control Inputs header (N.U.S.S.); patching breaks the normall.464
CH3 Signal Inputaudio—Signal input for channel 3 LPG circuit. Normalled to Signal Input header (N.U.S.S.); patching breaks the normall.464
CH4 Control Inputcv—CV input for channel 4 LPG circuit. Normalled to Control Inputs header (N.U.S.S.); patching breaks the normall.464
CH4 Signal Inputaudio—Signal input for channel 4 LPG circuit. Normalled to Signal Input header (N.U.S.S.); patching breaks the normall.464
XPREAD CV Inputcv—CV input for the XPREAD stereo spread parameter.464
Outputs (6)
CH1 Outputaudio—Individual output for channel 1 LPG. Patching removes channel 1 from the stereo Mix.464
CH2 Outputaudio—Individual output for channel 2 LPG. Patching removes channel 2 from the stereo Mix.464
CH3 Outputaudio—Individual output for channel 3 LPG. Patching removes channel 3 from the stereo Mix.464
CH4 Outputaudio—Individual output for channel 4 LPG. Patching removes channel 4 from the stereo Mix.464
Left Mix Outputaudio—Left channel of the stereo mix of all channels and Aux inputs, weighted by individual control levels and XPREAD.464
Right Mix Outputaudio—Right channel of the stereo mix of all channels and Aux inputs, weighted by individual control levels and XPREAD.464

Parameters 6

NameTypeRangeBehavior
CH1 CTRL Combo Potknob—Attenuates incoming CV at the control input. When no CV is patched and no N.U.S.S. header is in use, operates as a standalone panel control for the LPG circuit, setting both amplitude and frequency content of the passing signal.464
CH2 CTRL Combo Potknob—Attenuates incoming CV at the control input. When no CV is patched and no N.U.S.S. header is in use, operates as a standalone panel control for the LPG circuit, setting both amplitude and frequency content of the passing signal.464
CH3 CTRL Combo Potknob—Attenuates incoming CV at the control input. When no CV is patched and no N.U.S.S. header is in use, operates as a standalone panel control for the LPG circuit, setting both amplitude and frequency content of the passing signal.464
CH4 CTRL Combo Potknob—Attenuates incoming CV at the control input. When no CV is patched and no N.U.S.S. header is in use, operates as a standalone panel control for the LPG circuit, setting both amplitude and frequency content of the passing signal.464
XPREADknob—Sets stereo spread for all four channels. At 12:00 all channels are centered. Full CW distributes CH1 far left through CH4 far right. Full CCW reverses this, distributing CH4 far left through CH1 far right.464
