The most expressive
synthesizer ever

Discover an immense and animate sound that will send shivers up your spine.

At Arturia we believe that technology can enhance the connection between humans and sound. By engineering a machine to be as sensitive as it is powerful, where every subtle nuance and detail of performance is captured - the inner creative voice can be heard with more resolution than ever before.


A patented keybed architecture that has been years in the making: FullTouch® describes the keyboards’ dynamic aftertouch responsiveness - able to capture the precise position and acceleration of each key across the entire movement range.

With three new aftertouch modes, PolyBrute 12 invites a playing style that evolves and breathes; allowing composers, artists and synthesists alike to express their inner creative voice with unparalleled delicacy and detail - for a sound that can go from incredibly subtle to infinitely expansive in one motion.

More Info

12-Voice Polyphony

Create complex and lush harmonic structures, huge unison effects, dynamic sonic layering and split keyboard performances with PolyBrute 12’s expanded voice architecture. Use each hand and finger to command a unique aftertouch input per key for never-before-heard composition textures.

Morphée controller

It does more than just put morphing at your fingertips; you can discreetly map the X and Y touch axes plus the Z pressure axis to bring a new form of control to any destination parameters available in the Mod Matrix. You can even use the Morphée to randomize your sequences or arpeggios with spice, dice, and ratcheting!

The ribbon controller

We’ve resurrected the coveted ribbon controller, once a staple on classic hardware synthesizers. Positioned immediately above the keybed, you can assign it to your chosen modulation destination and glide effortlessly up and down to alter your sound.

sonic palette

PolyBrute 12’s voices, signature Brute oscillators, dual analog filters and modulation matrix allow for more sonic possibilities than any other synth - from luminous pads to synth-string plucks.

polybrute oscillators

The Oscillators

It all begins with two powerful Brute analog VCOs that generate sawtooth, triangle, and square waves simultaneously. Add edge with the Metalizer and low-end depth with sub-oscillator, as well as having cross-mod & sync controls right at your fingertips.

The Steiner & Ladder Filters

Add color and shape with two classic filter designs, configurable in series, parallel, or continuously variable. The first, a Steiner 12db/octave filter with continuous slope type, enhanced with signature Brute Factor feedback; the second, the legendary 24db/octave Ladder filter for that essential low-pass smoothness, supercharged with biting distortion.
