Build Your Analog Sound – Literally

Whether you’re looking to scratch that DIY itch or you’re finally ready to take the plunge into analog synthesis, Moog’s Mavis is a spectacular way to get immersed in 100% analog design. Sweetwater’s synthesists are impressed with just how versatile this lightweight powerhouse can be. It packs a punch that is right at home in any rig. Remove it from its housing and you’ve got a 24-point, voltage-controllable 44HP module that’s Eurorack-ready. Alongside a classic Moog Ladder Filter, the Mavis boasts a VCO (with PWM), a VCA, an LFO, and a 4-stage envelope generator. This mini-mono synth also proudly introduces Moog’s first analog wavefolder, diversifying opportunities with additive synthesis. With no soldering required, you can assemble the Mavis in an afternoon, regardless of skill level. Finally, the included protective cover will keep your Mavis clear of trouble in the studio or on the road.

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.

Moog Mavis Semi-modular Analog Synthesizer Kit Features:

  • Build-it-yourself model means authentic analog sound with no soldering required
  • Onboard 13-key baker’s octave means quick playback with full glide and KB scaling
  • 1 v/oct setup enables exploration of unusual pitch and tone relationships
  • VCO features Pulse Width Modulation to create even greater range of harmonic character
  • Sculpt classic-style Moog leads and licks with the -24dB Low Pass Ladder Filter
  • Crossfader-based LFO modulation allows you to utilize the 4-stage envelope generator to devise intriguing and uncommon contours
  • Diode wavefolding circuitry means analog additive synthesis is now a possibility
  • 24-point patchbay provides easy Eurorack integration at just 44HP
  • Included protective cover keeps your Mavis clear of dirt and grime, in the studio or on the road

The Moog M

Endless hours of fun and learning. Yes, I am new to semi-modular side of things. What a fantastic first purchase in this direction. No regrets.
Rated 5/5

Excellent Entry-Level Synth For Eurorack / Semi-Modular Exploration

The Moog Mavis was my choice to further my exploration into the Eurorack / Semi-Modular world.
I previously purchased the Moog Werkstatt when I initially heard about it as my first opportunity to own a piece of Moog gear.
I appreciated and enjoyed the ability to re-patch and explore the basics of sound design with that classic Moog sound.

The Mavis seemed like the logical next step as it greatly improved on the ability to explore in more detail.
Loved the packaging and included extras (patch cables & dust cover!), assembly was easy, well described and did not take long.
Somehow it even seems to sound even better since you helped build it (maybe not really but I had fun doing it).

Bottom line, the Mavis is a great little single oscillator synth with lots of potential for anyone wanting to explore sound design.
Works great on it's own but add a MIDI controller that has CV & Gate outputs and you have a fantastic way to do that.
I personally don't think you can go wrong with anything Moog, maybe a bit expensive but NOT disappointing in what you get!

Classic Moog Sound With Folding ?!

Sounds exactly like a Moog but has the added benefit of wave folding. I would recommend buying pass through patch cables to squeeze some more outta her.
Rated 5/5

Absolutely love it

It's really fun. It's smaller than I expected, but still a decent size. The new folding feature is really cool and helps to just create new sounds that was unable to with my current Moog sound studio. Right now I like it the best when used with my Mother 32. Look up the Moog videos on using with their other components and it'll be a good starting point.
Rated 4.5/5

Great first entry into the world of Moog

This is my first Moog synth, and it's a remarkably fun little unit. It feels well-made, and it was really fun assembling it. If you're on the fence at all, buy this thing!

Want real Moog sound? Take it from the die-hard analog synth masters here at Sweetwater: buy a Moog. It doesn't matter which one; their synths start at top quality and only go up from there. Sweetwater's relationship with Moog goes way back, and some of us fondly remember the last time Bob himself came to visit. Over the years, we've had the honor of watching Moog grow and evolve, and with synthesis experts like Daniel Fisher on staff, we're still one of the first companies to catch wind of new Moog products - they never fail to impress! Whether it's a classic reissue, a breakthrough new keyboard, or even a cool effects pedal, you can be sure anything you get from Moog will make you happy, and we'd love to tell you all about it.
