Mavis is a build-it-yourself analog synthesizer kit that delivers the huge depth of sound Moog is known for in a compact and feature-packed instrument. Assembly is extremely simple; users of any skill level can quickly assemble their own analog synthesizer with minimal tools and experience. Perfect for first time users and established synthesists alike, Mavis’ semi-modular design and 1-octave keyboard will get you started making sound immediately without the need for additional equipment (except for a speaker or headphones). 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.

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, and features a broad modular utilities section complete with attenuators, offsets, mults, and a flexible DC-coupled mixer.

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.
