Low Pass Gate

A-101-2 is a vactrol based combination of Low Pass filter (LP) and VCA and was inspired by the Buchla module 292. The term "Low Pass Gate" was created by Don Buchla and stands for a module that can be switched between low pass and VCA. The control (manually and via external CV) is responsible for fr..

Erica Pico LPG is our take on classical Don Buchla LPG designs. We use vactrols in the circuit for that signature sound, and we added some more features, like configurable resonance and built-in decay envelope.FEATURES:Classical LPG soundVCA and VCF modesConfigurable resonanceBuilt-in Decay envelope..

Passive Low Pass GateIn general, low pass gates (LPGs) control the amplitude and timbre of a signal by opening and closing a low pass filter. When the gate is closed, no frequencies are allowed to pass through (and no output is heard). As the gate begins to open, the lowest frequencies pass through ..

Dual Stereo Low Pass Gate and MixerThe Dual Stereo Gate (DXG) music synthesizer module is a Dual Stereo Low Pass Gate and Mixer. It follows in the footsteps of the QMMG, Optomix, RxMx, DynaMix, and LxD. Unlike its predecessors, the DXG is specifically oriented around mixing stereo signals, making it..

A two channel Low Pass Gate, providing simultaneous voltage control over amplitude and frequency content of a signal. It is in essence, a Voltage Controlled Filter Amplifier (VCFA) that has an extremely organic response to control signals.The Low Pass Gate is a classic West Coast synthesis circuit.-..

Dual Multimode Filter ArrayMeridian is a 14hp dual multimode filter array, designed to offer users a choice between 4 selectable filter types per side and 4 selectable filter modes per side, plus 2 effects (drive & phase shift) and the ability to ping the filter. This allows users the flexibilit..

Muzzle is an analog vactrol based 12dB/octave low pass filter and low pass gate. The resonance goes from smooth to increasingly acidic and bubbly towards the max setting. Muzzle can create very interesting percussive sounds when in self-oscillation which can be dynamically controlled through the pin..

Sosumi is a dual Low Pass Gate based on Buchla 292 design. It features two identical mild non-resonant circuits which utilize vactrols in order to provide simultaneous control over the Amplitude and Frequency of the input signal. Due to the nature of vactrols though each channel and each Sosumi will..

Resonant low-pass gate with variable filter slope, RC envelope generator, and slewSinc Bucina is the sequel to one of our first modules, Sinclastic Empulatrix, replacing the clamping VCA with a resonant low-pass VCF and VCA combo. The velocity- dependent Ping input offers classic release-only LPG be..

The Centaur’s Gates is a fully analog signal path dual multi-types gate. Each of its two channels can take many forms : a smooth and warm two poles filter, a ready to ping low-pass gate, a VCA with distorting feedback loop, or an aggressive filter reminiscent of the unfamous Korg MS20. Both versions..

The Steady State Gate is a novel and discrete multi-mode Low Pass Gate including an additional stage of timbre modifying circuitries.Features:6db/Oct Bandpass, 6dB/Oct Lowpass and 12dB/Oct Lowpass Filter ModesManual Frequency Cutoff Control and CV InputManual Resonance (Q-FACTOR) Control and CV..
