The Quad Multi-Mode Gate is a huge riff on the original Buchla 292 Quad Lo-Pass Gate, including a Mix Out and all of the original feature set. The QMMG offers additionally: HiPass mode, Voltage Controlled Feedback, Direct Coupling and Normalizations so that multiple channels may easily be used together to create Bandpass Gates, steeper HP, BP or LP Filters, or even something like a traditional Synthesizer Voice Architecture.

The QMMG contains no fewer than 8 Vactrols!

Like the 2018 reissue, the mode switching is done via analog pots instead of rotary switches, and the bottom board contains reverse power protection circuitry.
