## Arturia PolyBrute 6-Voice Analog Polyphonic Matrix Synthesizer – 61-Key

**Analog warmth. Deep sound design. Extraordinary performance control.**

The Arturia PolyBrute is a professional **6-voice analog polyphonic synthesizer** built for musicians, producers, composers and sound designers who want the character of true analog synthesis with an advanced modulation system and expressive hands-on control.

At the heart of the PolyBrute are **six analog voices, dual analog oscillators, dual-filter architecture and an extensive modulation matrix**—but what makes it especially powerful is its ability to create two different sonic states within a preset and smoothly **morph between them in real time.**

From evolving cinematic pads and atmospheric textures to aggressive basses, expressive leads, analog keys, sequences and experimental soundscapes, PolyBrute is designed to be an instrument you can both program and truly perform.

### How Does the Arturia PolyBrute Work?

PolyBrute begins with genuine analog synthesis.

Its analog oscillators generate the foundation of the sound. That signal can then be shaped through its filters, envelopes, LFOs, modulation system and effects.

But PolyBrute goes considerably further.

Each compatible preset can contain **two states—A and B.** Rather than simply switching between two sounds, PolyBrute allows you to continuously morph between them.

That means one performance can gradually evolve from dark to bright, smooth to aggressive, subtle to enormous—or into something completely different.

### The PolyBrute Matrix

One of PolyBrute's defining features is its powerful **12 × 32 modulation matrix.**

The Matrix acts as a central control system for sound design, presets, modulation and sequencing.

Instead of requiring a physical patch cable for every modulation idea, players can create sophisticated modulation relationships directly from the instrument.

Want an LFO to change a filter?

An envelope to affect an oscillator parameter?

A performance controller to transform multiple elements of a sound?

The Matrix gives sound designers an enormous amount of routing flexibility while keeping the creative process visual and hands-on.

### Two Analog Oscillators Per Voice

PolyBrute features **two analog VCOs** with extensive tone-shaping capabilities, including:

-   Saw wave
    
-   Triangle with Metalizer
    
-   Square with pulse-width control
    
-   Sub oscillator
    
-   Linear FM
    
-   Hard Sync
    

A dedicated noise generator further expands the available sonic palette.

### Dual Analog Filter Architecture

PolyBrute combines two different analog filter designs:

**12 dB/Oct Steiner-Parker Filter**  
Offers continuously variable low-pass, notch, high-pass and band-pass filtering along with resonance and Brute Factor control.

**24 dB/Oct Ladder Filter**  
Provides classic low-pass filtering with resonance and distortion capabilities.

Using the two filter personalities together opens the door to an enormous range of analog textures.

### Designed for Expressive Performance

PolyBrute isn't only about programming sounds—it is designed to let musicians manipulate them while performing.

Its **61-key velocity- and aftertouch-sensitive keyboard** is accompanied by multiple expressive controllers:

**Morphée 3D Controller** — A touch- and pressure-sensitive performance surface that can control multiple dimensions of a sound.

**Ribbon Controller** — Provides an additional touch-sensitive performance control directly above the keyboard.

**Pitch & Modulation Wheels** — Familiar real-time performance controls.

**Morph Control** — Move between the A and B states of a preset to create continuously evolving sounds.

Combined with the modulation matrix, these controls can turn a single patch into an extremely expressive instrument.

### 64-Step Polyphonic Sequencer

PolyBrute includes a built-in **64-step polyphonic sequencer** capable of incorporating notes and performance information into evolving sequences.

Its Matrix interface provides a visual way to create and manipulate sequences directly from the synthesizer.

An onboard arpeggiator and Matrix Arpeggiator provide additional tools for generating rhythmic and melodic movement.

### Built-In Stereo Effects

PolyBrute combines its analog synthesis architecture with integrated digital effects.

Available processing includes categories such as:

-   Chorus
    
-   Phaser
    
-   Flanger
    
-   Ring modulation
    
-   Delay
    
-   Reverb
    

This allows musicians to build expansive, performance-ready sounds without depending entirely on external effects processors.

### Studio & DAW Integration

PolyBrute can function as the centerpiece of a hardware studio while also integrating into computer-based production environments.

With **PolyBrute Connect**, musicians can manage presets and access the instrument through compatible Mac and PC workflows while retaining the tactile experience of the hardware synthesizer.

This combination makes PolyBrute equally at home in a professional recording studio, production room or hardware-focused creative setup.

### Who Is the Arturia PolyBrute For?

### Frequently Asked Questions

**Is the Arturia PolyBrute a real analog synthesizer?**  
Yes. PolyBrute uses analog oscillators and analog filters as the foundation of its synthesis architecture while incorporating digital control, modulation, sequencing and effects capabilities.

**How many voices does the PolyBrute have?**  
The original PolyBrute provides **6-voice polyphony**, allowing up to six voices to sound simultaneously depending on the selected performance mode.

**What does “morphing” mean on the PolyBrute?**  
A preset can contain A and B states. Instead of simply switching between them, PolyBrute can progressively morph parameters between those states, allowing sounds to transform during a performance.

**Does PolyBrute have aftertouch?**  
Yes. The 61-key keyboard supports velocity and aftertouch for more expressive performance.

**Can PolyBrute be used with a DAW?**  
Yes. It provides USB and MIDI connectivity, and PolyBrute Connect provides deeper integration between the hardware and compatible computer-based production workflows.

**Does PolyBrute have a sequencer?**  
Yes. It includes a 64-step polyphonic sequencer as well as arpeggiator functionality.

**Is PolyBrute good for live performance?**  
Its preset system, split/layer capabilities, morphing, Morphée controller, ribbon controller, sequencer and hands-on interface make it particularly compelling for musicians who want to manipulate sounds expressively on stage.

### An Analog Instrument Built for Exploration
