Grandmother is a semi-modular analog synthesizer with a built-in arpeggiator, sequencer and spring reverb tank. Start playing immediately with “no patching required”, and then explore an infinite sonic playground with Grandmother’s reconfigurable front panel. Grandmother’s circuits, spring reverb, and spirit are inspired by the classic Moog Modular Synthesizers, making this instrument a powerful addition to a Mother-32, DFAM or any Eurorack modular system.

The Grandmother is an analog semi modular, 32 key synthesizer released by Moog Music Inc. incorporating circuits based on the Moog modular synthesizer Model 15, and the Minimoog.

Moog’s Grandmother is a two-oscillator analogue monosynth. It has a semi-modular architecture. This means that unlike a fully modular system it has a hard-wired (or normalled) signal path and will play without the use of patch cables. However, a number of additional synthesis options are available via patching.

The keyboard section of the synth includes 32 full-size keys, pitch and modulation wheels, a glide (portamento) knob, and buttons to control playback of the arpeggiator and sequencer.

The Grandmother allows people of any skill level to get involved with analogue synthesis. It requires no patching experience. It features a built-in arpeggiator, sequencer and hardware spring reverb. It also features a reconfigurable front panel, and is controllable via MIDI. There are 41 individual patch points for sound programming, which allows the user the ability to customize their patches even further.
