Moog Matriarch Dark 49-Key Analog Synthesizer

Start with a chord, let the sequencer push it somewhere unexpected, then follow the patch cables as the sound turns into something entirely new. The Moog Matriarch Dark 49-key analog synthesizer combines four analog oscillators, up to four-note paraphonic playability and a 49-note Fatar keyboard with the exploratory architecture of a semi-modular system. Its 100% analog signal path brings together circuits derived from classic Moog designs, including Minimoog-based oscillators, a CP3-based mixer, 904A-based filters, 911-based envelopes and 902-based VCAs. A 256-step sequencer, multimode arpeggiator and stereo analog delay make evolving patterns and spacious textures accessible without patching, while 90 modular patch points open the instrument to deeper sound design. From stacked four-oscillator mono sounds to layered paraphonic sequences and expansive stereo patches, Matriarch brings performance, sequencing and experimentation into one flexible analog instrument.

Four Analog Oscillators Expand the Sonic Range

Matriarch's four analog VCOs can be stacked into a monophonic voice or distributed across two- and four-note paraphonic modes for chords, harmonies and interlocking melodic ideas. Each oscillator provides selectable waveshapes, with hard sync available on oscillators 2–4, while the discrete six-input mixer introduces the asymmetrical clipping behavior of Moog's classic CP3 module. Dual 24dB/octave analog filters can operate in parallel high-pass/low-pass, stereo low-pass/low-pass or series high-pass/low-pass configurations, providing multiple ways to shape harmonic content. Dual ADSR envelopes and stereo discrete VCAs complete an analog voice architecture that can move from overdriven monophonic bass to evolving paraphonic textures.

256-Step Sequencer Shapes Evolving Patterns and Performances

The onboard sequencer stores up to 12 patterns and provides 256 steps with as many as four notes per step, allowing paraphonic chords and melodic movement to become an integral part of sound design. The sequencer can also be decoupled from Matriarch's internal voice to control external gear independently. An arpeggiator complements this workflow with Order, Forward/Backward and Random modes, while the full-size Fatar keyboard provides velocity and aftertouch as patchable control sources. Pitch bend, modulation, variable glide, sustain and expression pedal support add further performance control for shaping patches in real time.

Stereo Analog Delay Extends the Signal Path

A stereo analog delay based on Moog's MF-104M and 500 Series effects provides up to 700 ms of delay with independent left and right delay times, feedback and I/O, plus Ping/Pong operation and MIDI or CV clock synchronization. Voltage-controlled mix and dedicated delay outputs allow the effect to become part of a larger patch rather than simply sitting at the end of the signal path. Combined with the stereo filters and VCAs, the delay can produce wide repeating textures that evolve alongside a sequence or performance. An additional analog LFO supplements the primary modulation oscillator for animating the delay, filters, VCAs and other destinations.

90 Patch Points Enable Deep Modular Exploration

No patch cables are required to begin playing, but Matriarch's semi-modular architecture provides 90 accessible 3.5 mm patch points—including 49 inputs, 33 outputs and two four-way unbuffered mults—for rerouting and expanding its internal signal flow. Three bipolar voltage-controlled attenuators with ring-modulation capability add another layer of signal and modulation shaping, while the primary modulation oscillator supplies sine, saw, ramp, square, stepped-triangle, smoothed-random, sample-and-hold and noise sources. Matriarch can also integrate with Mother-32, DFAM, Grandmother and Eurorack modular systems, extending its role beyond a standalone keyboard synthesizer.

Flexible Connections Integrate Stage Studio and Modular Gear

A rear-panel 1/4" external input routes guitars, drum machines and other sources through the instrument's analog circuitry, allowing Matriarch to function as an external audio processor as well as a synthesizer. Stereo 1/4" line outputs, 3.5 mm Eurorack-level outputs, dedicated 3.5 mm delay outputs and a 1/4" headphone connection provide flexible monitoring and routing, while five-pin MIDI In, Out and Thru join MIDI over USB for integration with hardware and computer-based setups. Combining classic Moog-derived analog circuits, paraphonic performance, deep sequencing and extensive modular connectivity, the Moog Matriarch Dark synthesizer is designed for musicians who want a self-contained instrument that can also serve as the center of a larger analog system.
