Moog Mavis Semi-Modular Analogue Synthesizer

Mavis is an expressive and inspiring analog synthesizer with patchable modular utilities and unmistakable Moog sound and quality.

When removed from its enclosure, the instrument becomes a 24-point CV-controllable module (44HP) ready to be installed into any Eurorack setup or Moog semi-modular system. Perfect for first-time users and established synthesists alike, Mavis’s semi-modular design and one-octave keyboard allow for immediate musical exploration without the need for additional equipment (except for a speaker or headphones).

Mavis mixes the familiar with the exotic, featuring 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’s clever presentation of synthesis modules and utilities makes for intuitive, creative experimentation and musical connection.

Assembling this synthesizer kit by hand invites the user to get closer to the circuits at the heart of this unique musical machine. The connection made with an instrument while building it is something inherent to the nature of all Moog synthesizers, and it has been since the days of the large format modular systems. With Mavis, users of any skill level can quickly build their analog synthesizer with minimal tools and experience (no soldering required) by using all the components included in the instrument's carefully curated packaging. Once the instrument is built, complete with its included protective cover, the owner is guided on their journey with Mavis through a selection of patch books and educational materials that encourage creative patching and sound design.

Full Range Analog Oscillator: Mavis’s Voltage Controlled Oscillator (VCO) with pulse-width modulation (PWM), waveform mixing, and mod source mixing delivers rich harmonic character and motion.

Voltage Controlled Filter: Sculpt your sound with the -24dB 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 4-stage envelope generator 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:This circuit generates a random CV pattern that can be patched to modulate other parameters, including setting Mavis into a “random sequencing” mode of performance.

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