The Gateway to Modular Exploration

Are you looking to get hands-on with the legendary Moog sound in a way that’s affordable, deeply educational, and incredibly fun? Tired of pre-built instruments that leave you wondering what’s happening "under the hood"? The Moog Mavis is the perfect choice! Meticulously created as an accessible, "build-it-yourself" analog synthesizer kit, Mavis invites you to assemble your own instrument, giving you a unique connection to its circuits before you even plug it in—and the best part? Absolutely no soldering is required.

The Right Amount of Power and Design

Designed as both a standalone desktop synth and a flexible 44HP Eurorack module, Mavis is as versatile as it is compact. While it stays true to the classic Moog philosophy, it introduces fresh, "exotic" elements—most notably, the first-ever diode wavefolder on a Moog instrument. This addition allows you to blend traditional, fat subtractive synthesis with aggressive, additive wavefolding, opening up a range of metallic, complex, and gritty tones that you won't find on any other Moog. It’s a powerful, personality-driven tool that makes learning the art of synthesis approachable for everyone.

Perfect Connections and Tactile Control

Mavis offers the ultimate solution for those ready to dive into the world of control voltage (CV). Featuring a 24-point patch bay, you have total authority to route signals, create unusual modulation paths, and integrate it seamlessly with your existing semi-modular gear or Eurorack setup. With its onboard 1-octave keypad and dedicated knobs for glide and scaling, you can start making music immediately without needing a separate keyboard. Whether you’re experimenting with the Sample and Hold circuit for random sequencing or using the flexible DC-coupled mixer, Mavis is designed to grow with your studio.

Everything You Need to Get Started

Because Mavis is a semi-modular instrument, it is "patched" internally, meaning it will produce sound as soon as you assemble it—no cables required. However, when you're ready to break those internal norms, the included patch cables allow you to rewire the instrument's signal flow entirely. The kit comes complete with everything you need, including the PCB, front panel, enclosure, protective cover, calibration tool, and patch cables. It is the perfect blend of DIY satisfaction and professional analog power.
