Moog Grandmother

Semi-Modular Analog Synthesizer

Moog Grandmother is a 32-key semi-modular analog synthesizer designed for hands-on sound creation, classic Moog bass and lead tones, and flexible integration with modular systems. Its internally normalized signal path lets you start playing without patch cables, while 41 patch points open up deeper routing, modulation, and external processing options.

Moog Grandmother Competitive Differences

• 100% analog sound engine with two voltage-controlled oscillators and classic Moog ladder filtering
• 32-note velocity-sensitive Fatar keybed for expressive performance
• 41 patch points for semi-modular routing with Eurorack, Mother-32, DFAM, and other modular gear
• Built-in hardware spring reverb that can process both internal and external sounds
• Integrated arpeggiator and 256-note sequencer with three sequence locations

Moog Grandmother Description

The Moog Grandmother brings vintage-inspired Moog modular circuitry into a playable, semi-modular keyboard format. With two analog oscillators, selectable waveforms, hard sync, linear FM, white noise, and external audio input, it gives producers and performers a wide analog palette for basses, leads, drones, effects, and experimental textures.

Its signal path includes a classic -24dB/octave Moog ladder low-pass filter with resonance, a patchable -6dB/octave high-pass filter, an analog ADSR envelope generator, a modulation oscillator, and a hardware spring reverb tank. The result is a synth that can sound warm, raw, smooth, or aggressive depending on how it is patched and played.

For performance, the 32-note velocity-sensitive Fatar keyboard is joined by pitch bend, modulation wheel, variable glide, an arpeggiator, and a 256-note sequencer. The semi-modular design makes it accessible for players who want immediate sound, while giving advanced users the patch points needed for modular integration and creative routing.

Built for studios, live rigs, electronic music production, and modular exploration, Moog Grandmother is a strong choice for musicians who want hands-on analog control, classic Moog character, and flexible connectivity in one instrument.
