Expressive analogue flagship

The Arturia PolyBrute is a six-voice analogue polysynth designed for expressive sound design and dynamic performance. Its architecture pairs dual oscillators per voice (with wavefolding (Metalizer), PWM, and linear FM) with a dual-filter section combining a Steiner-Parker multimode filter (12dB/octave, including high-pass and notch responses) and a ladder-style low-pass filter (24dB/octave, known for retaining low-end warmth even at high resonance). A deep modulation matrix (16 sources, 32 destinations) and intuitive hands-on interface encourage real-time exploration. Central to its identity is its morphing architecture, allowing seamless transformation between two fully realised sound states, from a soft pad to an aggressive lead – brought to life through Arturia's pressure-sensitive Morphée controller, which turns static patches into evolving textures. A clearly organised control panel supports immediate interaction. Performance tools (aftertouch, ribbon controller, assignable macros) and flexible routing extend its adaptability across studio and stage environments. The PolyBrute stands as a modern analogue platform that prioritises expression, experimentation, and fluid musical interaction.

Architecture and modulation

The PolyBrute is built for flexibility and movement, not just vintage sounds. Each voice combines two oscillators that deliver everything from sharp, metallic textures to warm, evolving pads. The signal then passes through two distinct filters: a Steiner-Parker multimode filter (capable of bright, cutting tones) and a ladder-style low-pass filter (for a rich, resonant bass). These filters can be routed in series or parallel, offering a wide spectrum of tonal interactions – from aggressive leads to layered soundscapes. Three envelopes, multiple LFOs, and a powerful modulation matrix enable complex routings reminiscent of modular workflows. Whether tweaking a single parameter or crafting modular-style patches, the PolyBrute gives musicians complete control in creating evolving textures, rhythmic motion, and deep parameter interaction – rather than static preset playback.

Performance and creative tools

PolyBrute's performance architecture turns sound design into a continuous, hands-on creative process. The Morph function lets performers blend between two complete sound states within a single patch, for seamless transitions or dramatic transformations. The pressure-sensitive Morphée controller adds three-dimensional control over multiple parameters simultaneously, while the ribbon controller and assignable performance controls provide fluid pitch gestures and expressive modulation. Deeply integrated into the modulation matrix, these tools allow complex mappings without interrupting creative flow. A polyphonic sequencer (with per-step automation) and a versatile arpeggiator – including matrix-based patterns – expand the dynamic, creative possibilities. An intelligent random patch function offers musically-coherent inspiration, supporting experimentation without sacrificing usability.

About Arturia

Arturia's success story began with software emulations of well-known analogue synthesizers such as the Moog Minimoog, Sequential Prophet-5, and Oberheim SEM. The popular software instruments included in the V Collection are still flagship products of the French developer today. Over time, Arturia has gradually expanded its range and now also offers a host of hardware devices, ranging from synthesizers and keyboard controllers to sequencers. Since then, the former software developer has thus also become a household name in the world of analogue synthesizers and other equipment.

Workflow and studio integration

PolyBrute adapts effortlessly to both studio production and live performance. Single, Split, and Layer modes allow flexible voice allocations for expansive pads, dual textures, or performance-focused setups. The built-in polyphonic sequencer records notes and parameter movements, while the arpeggiator introduces synchronised patterns and rhythmic variation. USB and MIDI connectivity enable direct DAW control, supported by the PolyBrute Connect software for detailed editing, automation, and preset management. Stereo outputs, analogue clock I/O, and multiple pedal inputs facilitate integration into hybrid rigs. Ongoing firmware updates have already expanded effects, routing flexibility, and workflow refinements, reinforcing its role as a contemporary analogue instrument that continues to develop alongside modern production workflows.

In the spotlight

Morphée controller and modulation matrix

Central to the PolyBrute's identity is its morphing system, which transforms sound design into an expressive performance. Each preset contains dual sound states that can be continuously blended, allowing gradual evolution or dramatic shifts as the music plays. The pressure-sensitive Morphée controller extends this concept with three-dimensional X/Y/Z control, enabling multiple parameters to move simultaneously through the modulation matrix. With its 16×32 routing architecture, players can shape complex behaviours – from subtle tonal shifts to radical structural changes – without breaking the musical flow. This approach brings modular-style flexibility to a polyphonic synthesizer, encouraging experimentation while remaining eminently playable and performance-oriented.

Quality instrument

Robert7183 29.09.2021

This has got to be the best hardware product from Arturia to date. A quality build, responsive controls, good firmware, excellent computer based editor and many realtime controls on the unit itself (ribbon, pitch and mod wheels and the morphee) make it a really expressive instrument. Like all synths, you really need 4 hands to play it in realtime but this beats most other synths hands down on the playability front.

The presets are good too. Its a hefty instrument so you wont want to move it around too much. Good for basses, leads etc like the matrixbrute is/was but this can do stunning strings/pads as well. Easy to create your own patches too. Recommended.

Brilliant

Martin475 01.03.2023

I have a Matrixbrute.
I was a bit worried that the Polybrute wouldn’t have the “fatness” of the Matrixbrute. I needn’t have.
It can be anything you want. Polite but equally dirty. Brilliantly laid out controls.
The matrix is not a gimmick.
It can be used for selecting patches, choosing modulations etc.
The randomiser is the best I’ve used in any synth. It’s not totally random as it seems to create new sounds out of existing presets.
I had the knob turned fully left and on turning it the sound went from a honky tonk piano like sound through to a cello and finally a distorted bass.
With no further editing!
Build quality is excellent.
When you get it first put it where you’ll keep it most often. Then let it warm up and then tune it.
I’ve had no problems doing that way.
100% recommend the synth and also Thomanns fantastic service.
Always deal with them. Best prices and also best customer service. Which is very important.

Excellent sound, profound capabilities & great integration

Othon 06.05.2021

This is one of the finest instruments I laid my hands on! It is very intuitive to learn (with great Tutorials by the Arturia team online) and it is incredibly musical. For someone who is a pianist and a composer as well as a producer/dj, it is a great gift, as it complements my creative work on all fronts.

One of the greatest surprises has been the excellent support for some questions I had from the Arturia team. I am truly amazed by the professionalism and passion of these guys! It makes the whole learning process and experience so much easier, enjoyable and meaningful! Well done Arturia team for both an exquisite creation and for taking care of us every step along the way!

Probably the best synth for the money

Jonathan M. 448 10.02.2023

The flexibility of the synth is amazing. The build quality is amazing. I've tried the competitors instruments in this price range and they don't compare. Would highly recommend
