The multicolored Moog Grandmother is a semi-modular analog synthesizer with a 32-note Fatar keyboard, an integrated sequencer/arpeggiator, a spring reverb, and 41 patch points compatible with the Mother-32, DFAM, and other Eurorack modules. The semi-modular design is pre-wired internally for making sounds without patch cables and is fully controllable via MIDI.

Both oscillators offer selectable waveshapes and can be hard-synced, while the dedicated analog LFO features audio-rate capabilities. The classic 24 dB low-pass ladder filter provides a frequency range of 10 Hz to 20 kHz, while the patchable 1-pole high-pass filter offers additional harmonic shaping. Additionally, the Grandmother offers a standard ADSR envelope generator and is complemented by a built-in hardware spring reverb.

The onboard sequencer offers three memory slots and each sequence can retain up to 256 notes. Additional features include USB MIDI, MIDI in/out/thru via 5-pin DIN, a patchable bipolar attenuator, a patchable 4-way mult, and a 1/4" external input for processing guitars, drum machines, and more. The Moog Grandmother ships with a power adapter, a power cord, a drawstring bag, and eight patch cables.
