QMMG

The QMMG, Quad Multi-Mode Gate, is a large riff on the Buchla 292 quad low pass gate, with a MIX output and the original feature set, plus a high pass mode, voltage controlled feedback, direct coupling and normalizations that let channels combine into band pass gates, steeper filters or a whole synthesizer voice. Each of its four channels has a signal input, a CONTROL input with its OFFSET knob, a FEEDBACK knob with its CV input, a MODE knob choosing between VCA, low pass and high pass, and its own output; all four are summed at the MIX output. It holds eight vactrols; this is the 2024 Black and Gold edition.
