PolyBrute Now Shipping

You’ve seen it in the hands of reviewers and artists, and now it’s your turn - the first PolyBrute orders are now shipping worldwide. Some orders may have already arrived, and the rest are on their way.

Imagine using 6 analog voices to craft a sound that's powerful, raw, and entirely yours. Imagine a sound existing in two states simultaneously in a single preset, with seamless morphing between them. Imagine multi-axis performance controls offering next-generation musical expression. Imagine instant and limitless modulation at your fingertips. Imagine a polysynth made by musicians, for musicians.

Imagine PolyBrute.

Evolution of the Brute sound

Raw, powerful, organic. The analog Brute voice is an unmistakable sonic force to be reckoned with - how about six at once?

PolyBrute's six-voice power starts with two Brute waveshaping oscillators. With sprawling timbral versatility from delicate airy pads to snarling stacked bass, these are six voices you can count on to excel in every application.

The tactile and reactive nature of analog synthesis is right at the heart of PolyBrute's architecture. Tame or animate the oscillators with an expanded array of multiple filters, envelopes and LFOs for absolute control over the analog domain. Once you've harnessed its sound sources, PolyBrute is your vessel for an inspiring voyage into sound.

a bold new chapter in the story of synthesis

PolyBrute’s morphing abilities let you perform, compose, and explore sound without boundaries.

Imagine being able to sweep all the parameter settings between two different patches all at once. PolyBrute goes even further with its groundbreaking ability to gradually morph between two completely different states within any patch.

Starting on a classic synth pad, then gradually adding a brighter, more digital-sounding layer.

From a Clavinet to a Wurlitzer, and everything in between.

Hear a moody plucked sound morph into a washed-out pad.

An aggressive lead going from thin to very large and detuned, thanks to the unison features.

Launch into an infinite continuum of inspiring new sounds in between.

For morphing to work, hands-on control is essential - PolyBrutes takes it to another level. The all-new Morphée three-dimensional performance touchpad ensures that intricate morphing expression is always right at your fingertips. Manipulate any facet of PolyBrute’s sound, from delicate morphing to extreme dynamic shifts, across the X, Y and Z axis in an instant.

It doesn't end there; PolyBrute is armed to the teeth with articulate controllers to give your performances and compositions the elusive human touch.

This unparalleled sonic flexibility and expressivity is what earns PolyBrute its place in synthesizer history - a trailblazer of creativity.

Sound Corner

PolyFlutes (Florian Marin)

PolyFlutes A mysterious, chillout ambient track with the duophonic aftertouch in the spotlight, made using only the Polybrute 2.0 Factory presets. No external FX were used in this demo.

Hold The_Line (JM Blanchet)

Hold The Line Melodic dreamy funky track reminding the 80s ambiences. All the synth parts and melodies come from PolyBrute, with the use of external Live drum samples.

Cool-Brute (Michael Geyre)

A funky jazz track based on the "Wurlinet" preset, which uses morphing to transform a "Wurlizer" style electric piano sound into a clavinet! The drum parts were also created entirely on the PolyBrute.

Spovtnik (Michael Geyre)

A trip into orbit using 9 Polybrute instances. Based on a string ensemble sound (Solistrings), a sequence (Spovtnik), and a lead sound (Mini Lead).

Lost In Space (JMB)

An ambient track created on one of the early Polybrute prototypes in summer 2019. It is made up of 6 different sounds played successively live in audio on a DAW. The sounds on this track use no external effects or additional synthesis sources - it’s all PolyBrute.

Ghost (Cubic Spline)

A dark progressive psytrance composition, with a triple-layer pad doing the heavy lifting on the atmosphere front. It uses 10 instances of the PolyBrute, with the kick and drums coming from my personal samples.

Bridges (Boele Gerkes)

A dreamy ambient track reminiscent of the deep atmospheres of old-school Berlin music. This track is based on 4 PolyBrute instances demonstrating the extensive possibilities of morphing, most notably with the "PPG 4.0" preset.

Between Ice And Fire (Euan Dickinson)

A track typically in the spirit of Massive Attack using 6 instances of PolyBrute to demonstrate the full extent of its power and rich sound.

Poly Synergy (Lily Jordy)

This minor melodic tune is made of 9 Polybrute presets sounds from Lily’s bank, and a conga loop for a richer percussion section. All effects are internal to the PolyBrute: no external plugins were used except Ableton Live 10’s compressors.

Softness (Simon Galifet)

A bewitching melodic track showing the spatial and ambient side of the instrument. A multitude of sounds, including “13 VCOs”, a pad sound “First Snowfall”, and 2 Sequences: “Floating points” and “Granular Freelance”. Everything but the percussion is made on PolyBrute.

Mars Geology (Simon Galifet)

A simple and straight techno track. Everything but the kick is coming from the PolyBrute. Based on the “Pulsar” preset with some SFX presets like “FX Hoover” and “Massacre”.

A Hands-On Analog Experience

PolyBrute puts all that analog power right up front with dedicated knobs and switches, offering unmatched control and immediacy.

Almost everything you touch also generates MIDI, so you can capture your every move as part of your DAW productions. Need some instant attitude? Crank up the enhanced Steiner filter’s Brute Factor. Want to change the cutoff on both filters at once? Grab the Master Cutoff knob. Time to move the floor beneath your feet? Dial in VCO 2’s sub-oscillator. It’s all right there in front of you.

Arturia have done it again! The brand new PolyBrute is the synth the world’s been waiting for. The 6 voice PolyBrute is the most inspiring synthesiser I’ve heard in a very long time. It really does sound amazing. Tweaking is a breeze and very addictive thanks to the eye-catching 8 x 12 matrix panel inherited from its grandad, the MatrixBrute .This makes it easy to keep tabs on the exceedingly deep modulation routings the synth offers. Much more than the sum of its parts. The PolyBrute may well be the best thing to happen this year. The best Brute yet.

Artists Corner

Take a touch of matrix, add a load of poly, stir it all together and what do get? Richness by the spadeful that’s what! Unison as big as a house one moment then pads as delicate as the wind. An absolute peach of a keyboard and my new best friend.

Artists Corner

As soon as I played the PolyBrute, just flicking through some of the many presets, I was sold. It sounded so alive and expressive and was much more fun to play than other modern polys out there.
