Product Description

The Moog Mavis is a build-it-yourself analogue synth kit that offers the massive sound you expect from a Moog in a compact format jam packed with features and options.

Mavis features Moog's iconic oscillator and filter circuits alongside a diode wavefolder - which is a first for a Moog instrument! Mavis combines traditional subtractive synthesis with additive wavefolding creating a powerful yet affordable Moog synth that makes learning synthesis or expanding your existing setup simple for anyone.

Through building it yourself, you can take a step closer to the circuits at the heart of Mavis and come away with a Moog analogue synthesizer that is uniquely yours! No soldering required and it can all be completed in no time at all by users of any skill level or experience! 

Key Features

  • Built-in keyboard with Glide and KB scaling
  • Full Range Analog Oscillator with Pulse Width Modulation
  • Voltage Controlled Filter
  • Audio Rate LFO and 4-Stage Envelope Generator
  • Wavefolding and Modular Utilities
  • Patchable Sample and Hold (S+H) circuit
  • 24-Point Patch Bay
  • Protective Cover

New to Moog: Wavefolding capabilities 

Mavis features a first for Moog - a wavefolding circuit, which allows for new additive synthesis options alongside traditional subtractive synthesis that Moog are renowned for. A wide variety of modular utilities are available such as attenuators, offsets, mults and a flexible DC-coupled mixer.

Features Galore

A Voltage Controllable Oscillator with PWM (Pulse Width Modulation), Waveform mixing, and Mod Source mixing, delivers rich harmonic character and motion. 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. 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 sonic possibilities. 

Assessible for Everyone 

Users of all skills levels can quickly assemble their own analogue synth in no time at all! Mavis semi-modular design and 1-octave keyboard will get you started making sound immediately and presents a perfect option for first time users and experienced synthesists alike! 

Use Mavis standalone or integrate into your existing setup

Mavis is capable of operating as a standalone instrument but with its patchable modular utilities, it can do a lot more! You can easily remove Mavis from its case to turn it into a 24-point CV controllable module (44hp) ready to be added to your Eurorack setup or alongside any of Moog's other semi-modular instruments!
