Make Noise MMG

Vactrol VCF + low pass gate that sweeps LP to HP

12 HP Eurorack module

The MMG (Multimode Gate) is a Vactrol-based voltage-controlled filter and low pass gate built on Make Noise’s QMMG core. It bridges East-Coast and West-Coast styles: a 12dB/oct response that sweeps continuously from Low Pass to High Pass, an aggressive resonance circuit that clips and can self-oscillate, and Strike/Accent inputs for percussive, dynamic animation. Dual AC- and DC-coupled inputs allow mixing audio with CV for asymmetrical behaviors, while an Automatic Gain Control stage keeps output levels in check at high Q.

Features

  • Vactrol-based voltage-controlled filter and low pass gate (QMMG core)
  • Continuously sweepable mode from Low Pass to High Pass (12dB/oct)
  • Voltage-controlled Mode, Frequency, and Q
  • Aggressive Q-Factor that clips and self-oscillates at high settings
  • Automatic Gain Control stage tames output level at high resonance
  • Strike input for Optomix-style percussive plucks
  • Accent input for X0X-style punch (pushes circuit to 110%)
  • Dual inputs: AC-coupled (with drive attenuator) and DC-coupled (unattenuated)
  • Frequency-to-Mode normalization enables quasi-bandpass / constant-power patches
  • Two cutoff CV inputs: one attenuverted, one unity-gain
  • Overload LED and Q-Clip LED for visual feedback
  • Mixes two signals or combines control + audio for asymmetrical behaviors
