Moog Mavis

by Moog


Compact yet mighty.

As a stand-alone instrument, Mavis is a straightforward analog synthesizer with patchable modular utilities and the unmistakable Moog sound and quality. Easily remove Mavis from its case and it becomes a 24-point CV controllable module (44hp) ready to be installed into your Eurorack system or alongside Moog’s other semi-modular instruments.

Mixing the familiar with the exotic, Mavis features Moog’s legendary oscillator and filter circuits alongside a diode wavefolder – the first analog wavefolder to appear on a Moog instrument. Combining traditional subtractive synthesis with additive wavefolding and oozing with personality, Mavis’ clever presentation of synthesis modules and utilities ensure deep creative synergy and musical connection. 

Mavis is a powerful, fun, and low-cost Moog that makes learning synthesis or expanding an already-advanced studio setup approachable for anyone looking to explore classic analog sound in a new way.

Legendary Moog Sound From a Build-It-Yourself Kit

Get closer to the circuits at the heart of Mavis and come away with a Moog analog synthesizer that is uniquely “yours”. No soldering is required and can be completed by any skill level in an afternoon.

Powerful Patch Bay Toolbox

A powerhouse on its own, Mavis was also designed to enhance any interconnected Moog semi-modular setup or Eurorack system. In 44HP, the synthesizer offers incredible value with two oscillators, full ADSR, ladder filter, sample and hold, wavefolding, attenuators, mixer, mults, and much more for more complex musical arrangements.

Built-in keyboard with Glide and KB scaling
As a standalone instrument or as a 44HP Eurorack module, Mavis adds an expressive 1 v/o controller to any setup with the flexibility to dial in experimental new pitch relationships via the KB scale knob and explore musical intervals that go beyond the established standards. 

Full Range Analog Oscillator 
A Voltage Controllable Oscillator with PWM (Pulse Width Modulation), Waveform mixing, and Mod Source mixing, delivers rich harmonic character and motion. 
Voltage Controlled Filter 
Sculpt your sound with the -24-dB Moog Low Pass Ladder Filter, delivering the sonic power behind the distinct sounds of Moog basslines and leads. 
Audio Rate LFO and 4-Stage Envelope Generator 

Mavis uses crossfaders in its modulation routing instead of switches, allowing you to blend between a variable shape LFO and four stage envelope generators for interesting and unusual modulation contours. 
Wavefolding and Modular Utilities  
Mavis features Moog’s first-ever wavefolding circuit, allowing for additive synthesis to sit alongside traditional subtractive synthesis, unlocking sounds not heard from a Moog before. Mavis also features a broad modular utility section complete with attenuators, offsets, mults, and a flexible DC-coupled mixer providing the tools needed for creative patching and sound design. 
Patchable Sample and Hold (S+H) circuit
Generates a random CV pattern that can be patched to modulate other parameters, including setting Mavis into a "random sequencing" mode of performance. 
24-Point Patch Bay 
Mavis is eager to play along with other voltage-controlled devices (especially with Moog’s other semi-modular instruments), and its useful collection of utilities and flexible control voltage routing allow for intricate dialogue between them.

Protective Cover
Mavis includes a fitted protective cover for use during studio downtime or taking your instrument on the go.

Meet Mavis: A Moog Semi-Modular Analog Synthesizer

To showcase the sonic range of Mavis, we documented a series of original synth-centered compositions by four unique electronic artists. These songs were written and performed inside each artist’s personal creative space, demonstrating how they use Mavis as part of their larger production setups. The seven songs performed in this short film span genres and styles, illustrating how Mavis easily integrates into a variety of modern electronic music workflows.
