New $499 Two-Voice Mini-Modular Synthesizer, Pluto

[embedded content]

Modern Sounds has announced the availability of Pluto, a new compact two-voice mini-modular synthesizer.

Here’s what they have to say about it:

“Pluto is compact and portable, with abilities that belie its small size. Five channels of modulation (named for the five moons of Pluto), two voices, two sequencers, a mini-keyboard, and onboard effects make Pluto its own complete sound environment, but it can happily play with all your other gear.

The design of Pluto draws from a legacy of portable electronic instruments, from the Buchla Music Easel to 80s Casio synthesizers. With a focused, approachable interface, Pluto invites exploration.”

  • Create complex, randomized sequences
  • Low-aliasing digital oscillators, wavetable oscillators
  • Rechargeable battery
  • Built-in delay and reverb effects
  • Mini touch keyboard

Moog Mavis Synthesizer Review

[embedded content]

In this Bloom Music video, Donald Jordan gives an in-depth review of the new Moog Mavis synthesizer.

Mavis is a DIY synth (no soldering required) that offers an affordable, but powerful, synth voice, with classic Moog sound. It can be used as a standalone synth, or removed from its case to be used as a 24-point CV-controllable 44HP Eurorack module.

Jordan says that it’s a bargain and an excellent sounding synth, but that its relatively rigid audio path means that it’s much more interesting when used as part of modular system.

Topics covered:

Intro: 00:00
Architecture: 1:47
Oscillator: 3:11
Filter: 5:20
Wave Folder: 7:44
Modulation: 13:02
Patchbay: 16:08
Eurorack Use: 22:16
Patches: 24:03
Conclusion: 27:36

Moog Intros $349 Mavis Analog Semi-Modular Eurorack Synth Voice

[embedded content]

Moog Music today introduced Mavis, an all-in-one semi-modular analog synth voice in Eurorack format.

Mavis is a DIY synth (no soldering required) that offers an affordable, but powerful, synth voice, with classic Moog sound. It can be used as a standalone synth, or removed from its case to be used as a 24-point CV-controllable 44HP Eurorack module.

Mavis brings new sonic capabilities to Moog’s palette of Eurorack systems.

The compact synth features Moog’s archetypal oscillator and filter circuits, but also features a diode wavefolder, the first analog wavefolder to appear on a Moog instrument. Combining traditional subtractive synthesis with additive wavefolding means that Mavis takes the traditional Moog sound into new territory.

With Mavis, users of any skill level can quickly build an analog synthesizer, with minimal tools and experience. No soldering is required. Once the instrument is built, Moog introduces you to the synth’s capabilities through a selection of patch books and educational materials, designed to encourage creative patching and sound design.


  • 24-Point Patch Bay: Mavis features a useful collection of utilities and flexible control voltage routing.
  • Full Range Analog Oscillator: Mavis’s Voltage Controlled Oscillator (VCO) with pulse-width modulation (PWM), waveform mixing, and mod source mixing delivers rich harmonic character and motion.
  • Voltage Controlled Filter: Sculpt your sound with the -24dB 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 4-stage envelope generator, 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, and features a broad modular utilities section, complete with attenuators, offsets, mults, and a flexible DC-coupled mixer.
  • Patchable Sample and Hold (S+H) Circuit: This circuit generates a random CV pattern that can be patched to modulate other parameters, including setting Mavis into a “random sequencing” mode of performance.
  • Protective Cover: Mavis includes a fitted protective cover for use during studio downtime or taking your instrument on the go.
  • Seamless Configuration with Eurorack Systems & Moog’s 60HP Semi-Modular Synths – In 44HP, the synthesizer offers two oscillators, full ADSR, ladder filter, sample and hold, wavefolding, attenuators, mixer, mults, and much more.

Moog Mavis Audio Demos:

A Nod to Moog’s DIY Beginnings

Moog notes that Mavis isn’t the first DIY instrument from Moog – in fact, the company was built on the build-it-yourself kit.

In 1949, a teenage Bob Moog discovered a copy of Electronics World that featured an article with details on how to build an electronic musical instrument at home. Shortly after, he built his first model of the instrument, a theremin, from plans published in the magazine. By 1953, Bob and his father established R.A. Moog to market and sell theremin kits out of their home in Queens, NY.

With the release of Mavis, Moog celebrates its roots by providing the end user with the unique experience of constructing their own instrument. Every Mavis is custom built and hand assembled—like the instruments Bob Moog built years ago and the synthesizers and theremins that Moog’s employee-owners assemble by hand to this day.

Pricing and Availability:

The Moog Mavis synthesizer is available now for $349 USD.

Free Wavetables For The Novation Peak & Summit Synthesizers

[embedded content]

Sound designer Anton Anru shared this video demo of a free collection of 50 custom wavetables for Novation Peak and Summit.

The collection is designed to expand the sound palette of these synths. The wavetables offer a wide range of tones, from “warm, soft, analog-style to bright, metallic, harsh”.

“The waves sound nice in a ‘static mode’,” notes Anru, “and they give a pleasant movement, when the Shape is modulated by LFO, Envelope or other sources.”

Pricing and Availability

Anru has released the wavetables as a free library, but donations are appreciated.

20 Sounds On The Erica Synths DB-01 Bassline Synthesizer

[embedded content]

This video, via Richard DeHove, explores the sonic range of the Erica Synths DB-01 bassline synthesizer.

The video explores the sonic range of the Erica Synths DB-01, using 1 pattern with 20 different bass sounds.

Here’s what DeHove has to say about the video:

On a recent video one comment said “Cool machine, but it only has one sound”. The truth or otherwise of that here is in the ear of the beholder.

With the very distinctive Polivoks filter and a single oscillator maybe every sound does sound a bit the same? And this is a bass synth after all. But to my ears there is a lot of difference. At the very least, the different settings emphasize different parts of the pattern, in this case the pitchmod drum-like thumps and the noisy highs.

New Lisa Bella Donna Album, Photophobia, Conjures Paranormal Experiences, “Timeless Spaces”

This week, Synthesist and composer Lisa Bella Donna released a new album, Photophobia. The album uses Moog Modular System, ARP 2600, ARP Axxe, ARP String Ensemble synths to evoke a spooky vibe.

She says of the album tracks:

“These compositions are old stories from the late 70s & early 80s.

Reflections and impressions of a few real life paranormal experiences I had growing up in deep rural West Virginia. Far away journeys in timeless spaces. Transfigurations of twilight on hallowed ground. Astral apparitions. Everlasting passageways through the electronic forests…

Lifelong lasting impressions for sure. Come away with me…”

Photophobia is available for streaming (free) and purchase/download on Lisa Bella Donna’s Bandcamp page.
