The Matriarch is one of several of Moog’s recent semi-modular synthesizers. It’s a patchable, Eurorack compatible, four-note, paraphonic, analog synthesizer with a built-in sequencer, arpeggiator, stereo ladder filters and stereo analog delay. For a slightly more affordable option, users can look to the Moog Grandmother, a similar semi-modular monosynth.
