Moog Grandmother (2018)

Name: Moog Grandmother
Brand: Moog

A semi-modular analog monophonic synthesizer released by Moog Music in 2018.

Overview

The Moog Grandmother is a semi-modular analog synth from Moog Music, introduced in 2018. It sits in a line of instruments that carry the Moog legacy forward, alongside the Mother 32, Subsequent 37, Matriarch, and Moog One. It is monophonic, with two analog oscillators and a third analog oscillator whose range can be extended by patching. It has a 4-pole ladder filter and 41 patch points for modular integration. Built-in features are an arpeggiator, a sequencer, and a spring reverb tank. The design takes its inspiration from vintage Moog modular systems, and it targets newcomers and experienced users who want hands-on synthesis.

Context

The Grandmother was positioned as a sub-$1000 semi-modular synthesizer. That made it one of Moog's more accessible analog instruments at launch. It shares design language with the Mother 32 and other modern Moog synths, and it is part of a broader effort to bring modular synthesis to a wider audience. It draws direct inspiration from vintage Moog modular systems and adds modern usability features.
