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.

Supplier's Notes:
East Beast

Fully analogue East Coast style semi-modular synthesizer

What's the first thing you think of when you hear the word "synthesiser"? Close your eyes and think about.

Anyway, for a lot of people, the word synthesiser invokes visions of big filter cutoff knobs, envelope generators, and importantly, big fat-sounding voltage-controlled oscillators. These are the hallmarks of East Coast-style synthesis.

East Beast is a fresh take on these old-school concepts with a few beastly twists thrown in here and there.

Furthermore, you can pop East Beast out of its included enclosure and it transforms right into a 40HP eurorack module
East Beast's oscillator, designed in partnership with Pittsburgh Modular Synthesizers, is a part of their 5th generation of analogue oscillators stemming from a super-serious 10 years of continued research into analogue oscillator development.

Its circuitry is not a clone or based on any outside designs. It is made with 100% modern components. This keeps it very stable, and giving it a super rich, and unique sound.

Most of the filters you are used to hearing are transistor ladder filters or copies of transistor ladder filters. East Beast's filter is not one of those. Pittsburgh's whole goal of making this filter for East Beast was to create a filter that's creamy smooth with no dead spots, a very common phenomenon in all filters, but check it out. This one's got no dead spots. From nasally to biting and elsewhere, it's all one large sweet spot.

East Beast's filter is a multi-mode filter, meaning it can be used as a low pass filter, high pass filter, bandpass filter, or a combination of the three for an even wider sonic palate.
Shape the beast in your own image
To further sculpt the sounds Cre8audio has included an envelope generator & LFO. The custom envelope circuit creates a snappy, percussive attack for expressive performance. The dual range LFO opens up a wide range of LFO and audio rate modulation possibilities.

Get patched.
Semi-modular means that the East Beast will work without any patch cables or anything. But what fun is that? Who doesn't want to have their own personal spaghetti mess of cables sticking out of their synthesizer to get wacky with?
East Beast has basically 9 different patchable modules (Oscillator, filter, envelope, VCA, LFO, multi-mod tool, sequencer, MIDI to CV converter, and button keyboard) with a whopping 18 Eurorack compatible patch points to plug into itself and your other gear. All for your patching pleasure.

As well as this, East Beast has MIDI in and a fancy MIDI thru so you can chain multiple MIDI monstrosities together- you can plug in a MIDI controller into East Beast and do as you wish.

But wait, there's more! East Beast includes quite a few additional performance features. You can dive in and dive in with its built-in tap tempo clock, arpeggiator, and sequencer. There's a lot of opportunities to inject in some randomness too.
