Moog GrandMother Analog Synthesizer

Moog introduces at The Moogfest a new analog synthesizer named Grandmother, which offers a classic housing form, but is equipped with colored modules, some of which allow even cable connections.

The Moog Grandmother is inspired by the classic vintage Moog Modular synthesizers designed by Bob Moog during the ’60s and ’70s.

It is the first newly developed key synthesizer of the traditional manufacturer since the Sub 37 presented in 2014.

Grandmother is described as a semi-modular analog synthesizer featuring a built-in arpeggiator along with a sequencer and spring reverb.

Based on the previous semimodular Eurorack synthesizers the new Moog Grandmother synthesizer consists of nine synthesizer modules and a 32-key keyboard.

The modules are already pre-wired but can be linked with other Euroack modules via about 40 patch points.

In addition, Grandmother features an “External Audio Input”, which should allow injecting audio signals from other instruments directly into Grandmothers analog filter, spring reverb, and amp circuits.

For the standard components, such as the two oscillators (cyan) and the 4-pole ladder filter (green) Moog used revised circuits from the old Model 15.

Highlights include the arpeggiator / sequencer (yellow), the three sequences with each store 256 notes and an analog spring-reverb (red), which can also be fed with external signals.

Although the Grandmother only has one envelope generator, the modulation element can control several parameters and be used right up to the audio range for FM tones.

A mixer and a utility section can also be used to mix several control signals and to amplify or attenuate them via an attenuator.

As usual with modular synthesizers, no patches can be saved. The user has to adjust the sound each time anew and can record it for example in a sampler.


  • ¼” External audio input for guitars, drum machines, and more.
  • Semi-modular – no patching is required
  • Easy to use Arpeggiator and Sequencer
  • Store up to 3 sequences with up to 256 notes each
  • 2 Analog Oscillators with selectable waveshape and hard sync
  • A classic 4-Pole 10Hz-20kHz Ladder filter
  • Patchable 1-Pole High Pass filter
  • Analog ADSR Envelope Generator
  • Analog LFO with audio-rate capabilities
  • 32-note Fatar keyboard with velocity
  • All normalized connections can be interrupted for full modularity
  • DIN MIDI In/Out/Thru and USB MIDI
  • Patchable bipolar attenuator
  • Works with Mother-32, DFAM, Eurorack modular systems and more
  • 41 patch points with 21 inputs, 16 outputs, and a Parallel-Wired 4-jack Mult

Moog wants to sell the first 500 devices at the Moogfest for $ 900 – along with an associated DENIM jacket. So we expect the Grandmother with prices of about 1100 €. Delivery dates has not yet announced.
