Moog Mavis Semi-modular Analog Synthesizer Kit and Eurorack Module

Authentic analog arsenal

Moog has spared no effort in ensuring the maximum array of analog offerings, despite what the size might suggest. Get to gliding with the expressive 1 v/oct scale and explore unusual pitch relationships, thanks to the KB scale knob and onboard baker’s octave of keys. Build rich harmonic character with the mixable saw/square VCO, which features Pulse Width Modulation to fine-tune your waveform. Harness the power of classic Moog basses and leads with the VCF, a sonic sculpting tool with a -24dB Lowpass Ladder Filter. Moog opted for crossfaders over switches in their modulation, allowing you to variably shape the LFO, with a 4-stage envelope generator to discover compelling and unexpected modulation contours. Mavis doesn’t stop at Moog-classic subtractive synthesis, however; they’ve also provided an additive synthesis option via a totally analog diode wavefolder, drastically broadening your sonic potential.

Dropping anchor in patchbay

Taking its modular roots to heart, Mavis can be removed from its housing (or ignore the housing altogether, as you build it) to fit into any Eurorack setup, so long as you’ve got the 44HP to spare. A 24-point patchbay enables total CV control, easily integrating into your current or prospective rig. For the adventuresome sound designers, the patchable Sample and Hold circuit is ideal for adding texture and color to any sequence or progression.

For musicians, producers, and synthesizer enthusiasts seeking a versatile, hands-on instrument that bridges classic analog warmth with modern modular flexibility, the Moog Mavis Semi-modular Analog Synthesizer Kit and Eurorack Module offers an exceptional solution. Designed to inspire creativity and provide deep sonic exploration, this semi-modular synth kit invites users to build, patch, and customize their sound, making it ideal for both beginners wanting to learn synthesis and experienced artists looking to expand their sonic palette.

At the heart of the Mavis is its fully analog architecture, featuring a single voltage-controlled oscillator (VCO) capable of producing continuously variable sawtooth and square waveforms. This means you get rich, authentic analog tones with the ability to morph wave shapes seamlessly, allowing for a wide range of timbres from bright, buzzy leads to smooth, mellow pads. The inclusion of wavefolding further enhances the harmonic complexity, giving you access to unique textures that stand out in any mix.

The semi-modular design includes a 23-point patch bay, offering extensive connectivity for experimenting with signal flow and modulation. This feature empowers you to route audio and control voltages freely, fostering an environment for innovation without the need for external modules. Whether you want to integrate the Mavis into an existing Eurorack setup or use it as a standalone instrument, the flexible patch bay encourages hands-on manipulation and personalized sound design.

Complementing the oscillator is a classic 4-pole lowpass ladder filter, renowned for its smooth, musical tone shaping. This filter lets you sculpt your sound with precision, cutting off high frequencies to create warm basses or crisp leads. The single ADSR envelope generator offers dynamic control over amplitude and filter behavior, enabling expressive note articulation, while the onboard LFO with triangle and square waveforms provides modulation options for vibrato, tremolo, or rhythmic effects. The sample and hold function introduces random stepped modulation, perfect for generating unpredictable sequences or experimental textures.

The Mavis features a compact 13-button keyboard that lets you play monophonic lines with expressive glide and keyboard scaling, ensuring smooth pitch transitions and consistent tracking across the range. Its analog output includes a 1/8″ jack suitable for headphones or line-level connections, making it easy to integrate into your existing audio setup. Powered by the included 12 V DC supply, the unit is ready to perform right out of the box. Measuring 44 HP in Eurorack width, with dimensions of approximately 8.93 inches wide, 5.23 inches deep, and just 1.53 inches high, this lightweight 0.94-pound module is portable and space-efficient.

The Moog Mavis is perfect for a variety of use cases—whether you’re crafting evolving soundscapes in a studio environment, improvising live performances, or experimenting with modular synthesis as a hobby. Its semi-modular nature makes it accessible for those new to synthesis, while its deep patching capabilities satisfy seasoned modular users seeking a compact and powerful voice. The hands-on kit format also offers a rewarding building experience that deepens your understanding of analog synthesis.

Confidently priced at ₹31,990 on sale, down from ₹33,990, the Moog Mavis Semi-modular Analog Synthesizer Kit and Eurorack Module represents a compelling investment in sound design and musical expression. It combines the legendary Moog sound with modular versatility in a compact package that will inspire creativity for years to come.
