Tags: Semi-modular synthesisers

Notes: As a stand-alone instrument, Mavis is a straightforward analogue 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.

Mixing the familiar with the exotic, Mavis features Moog's legendary oscillator and filter circuits alongside a diode wavefolder - the first analogue wavefolder to appear on a Moog instrument. Combining traditional subtractive synthesis with additive wavefolding and oozing with personality, Mavis' clever presentation of synthesis modules and utilities ensure deep creative synergy and musical connection.

Mavis is a powerful, fun, and low-cost Moog that makes learning synthesis or expanding an already-advanced studio setup approachable for anyone looking to explore classic analogue sound in a new way.

Get closer to the circuits at the heart of Mavis and come away with a Moog analogue synthesizer that is uniquely "yours". No soldering is required and can be completed by any skill level in an afternoon.

A powerhouse on its own, Mavis was also designed to enhance any interconnected Moog semi-modular setup or Eurorack system. In 44HP, the synthesizer offers incredible value with two oscillators, full ADSR, ladder filter, sample and hold, wavefolding, attenuators, mixer, mults, and much more for more complex musical arrangements.

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 allows for intricate dialogue between them.

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, 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:

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.

Notes: A massive semi-modular system in a small case with the footprint of a laptop. Cascadia has MIDI in/out/thru/USB, Eurorack compatible signal levels and pro-level audio I/O to interface with the rest of your studio or get your studio started.

Modern Analogue Architecture

Cascadia is packed with a mix of classic East and West Coast synthesizer blocks. Normalized connections let you get straight to the sounds inside. Or, let your imagination run wild and patch any of the modules together however you choose. Make small tweaks to the architecture, or re-route the entire synth to your liking- the choice is yours!
