QMMG
Quad Multi-Mode Gate: a four-channel vactrol-based gate/filter with VCA, Low-Pass Gate, Low-Pass Filter, and High-Pass Filter modes per channel, voltage-controlled feedback, direct coupling, normalizations for bandpass and complex filter configurations, and a summed Mix Out.446
Capabilities 5
- Lowpass Gatelowpass-gate
- Four vactrol-based channels each capable of operating as a Low-Pass Gate (BOTH mode), combining amplitude and frequency domain control with acoustic transient characteristics.446
- Multimode Filtermultimode-filter
- Each of the four channels has a MODE SELECTION rotary switch with VCA, BOTH (LPG), LP, and HP settings, enabling multimode filtering per channel.446
- Vactrol-basedvactrol
- Contains no fewer than 8 vactrols across its four channels, giving it the characteristic non-linear response of the Buchla 292.446
- Vcfvcf
- 446
- Voltage-Controlled Amplifiervca
- In VCA mode each channel operates as a voltage controlled amplifier with non-linear response and optional feedback gain.446

| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (12) | |||
| CH1 Control IN | cv | — | Direct coupled, highly sensitive CV input for channel 1's gate; adds to or subtracts from the Control Offset. CH.2 Control IN is normalized to CH.1 Control IN.446 |
| CH1 Feedback Control IN | cv | — | Direct coupled CV input controlling feedback amplitude for channel 1. Added to the Feedback Manual Control; allows higher feedback amounts than the knob alone.446 |
| CH1 Signal IN | mixed | — | Direct coupled signal input; accepts audio or CV. CH.2 Signal IN is normalized to CH.1 Signal OUT.446 |
| CH2 Control IN | cv | — | Direct coupled highly sensitive CV input for channel 2's gate. Normalized to CH.1 Control IN.446 |
| CH2 Feedback Control IN | cv | — | 446 |
| CH2 Signal IN | mixed | — | Direct coupled signal input; accepts audio or CV. Normalized to CH.1 Signal OUT.446 |
| CH3 Control IN | cv | — | Direct coupled highly sensitive CV input for channel 3's gate. Normalized to CH.4 Control IN.446 |
| CH3 Feedback Control IN | cv | — | 446 |
| CH3 Signal IN | mixed | — | Direct coupled signal input; accepts audio or CV. Normalized to CH.4 Signal OUT.446 |
| CH4 Control IN | cv | — | 446 |
| CH4 Feedback Control IN | cv | — | 446 |
| CH4 Signal IN | mixed | — | 446 |
| Outputs (5) | |||
| CH1 Signal OUT | mixed | — | Processed output for channel 1. Normalized to CH.2 Signal IN. Inserting a plug removes this signal from the MIX OUT.446 |
| CH2 Signal OUT | mixed | — | 446 |
| CH3 Signal OUT | mixed | — | 446 |
| CH4 Signal OUT | mixed | — | 446 |
| MIX OUT | mixed | — | Sum of all four channel outputs. A channel is removed from the mix when a plug is inserted at its individual Signal OUT.446 |
Parameters 12
| Name | Type | Range | Behavior |
|---|---|---|---|
| CH1 Control Offset | knob | 0V – 8V | Applies a manual offset voltage to the gate control signal. Works together with Control IN as a combined cutoff/gain control.446 |
| CH1 Feedback Manual Control | knob | 0% – 100% | In VCA mode, feedback at noon leaves signal unattenuated; above noon adds gain, below noon attenuates. In BOTH mode, feedback damps ringing. In LP/HP modes, feedback causes highly unstable non-linear resonance.446 |
| CH1 Mode Selection | knob | — | Selects gate operating mode: VCA, BOTH (Low-Pass Gate), LP (Low-Pass Filter), or HP (High-Pass Filter).446 |
| CH2 Control Offset | knob | 0V – 8V | 446 |
| CH2 Feedback Manual Control | knob | 0% – 100% | 446 |
| CH2 Mode Selection | knob | — | Selects gate operating mode: VCA, BOTH (Low-Pass Gate), LP (Low-Pass Filter), or HP (High-Pass Filter).446 |
| CH3 Control Offset | knob | 0V – 8V | 446 |
| CH3 Feedback Manual Control | knob | 0% – 100% | 446 |
| CH3 Mode Selection | knob | — | Selects gate operating mode: VCA, BOTH (Low-Pass Gate), LP (Low-Pass Filter), or HP (High-Pass Filter).446 |
| CH4 Control Offset | knob | 0V – 8V | 446 |
| CH4 Feedback Manual Control | knob | 0% – 100% | 446 |
| CH4 Mode Selection | knob | — | Selects gate operating mode: VCA, BOTH (Low-Pass Gate), LP (Low-Pass Filter), or HP (High-Pass Filter).446 |
