PolyBrute 12 is a 61-key polyphonic synthesizer with a FullTouch keyboard, stereo dual-filter architecture, near-infinite sound morphing capabilities - that redefines musical expressiveness.

Continuing the legacy of its predecessor as one of the most powerful and expressive analog synths ever made, PolyBrute 12 goes a step further, redefining musical expressiveness with an expanded 12-voice architecture and groundbreaking Full Touch® technology polyphonic keyboard.

This synth isn't just an instrument; it's a conduit to unprecedented soundscapes.

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.

This, combined with its Brute oscillators, intuitive interface, elegant modulation Matrix and advanced software companion make PolyBrute 12 a synth for the ages - a matrimony of Brute force and human touch.

The most expressive synthesizer

With a FullTouch® keyboard, Morphée multi-axis control, ribbon controller, three pedal inputs - this instrument offers more ways to express oneself than anything else available.

Limitless sound design

Its state-of-the-art oscillators, ladder and Steiner-Parker filters, innovative preset-morphing, 32 effects and modulation matrix open unrivaled sound-design possibilities.

Seamless DAW integration

Thanks to PolyBrute Connect, going from in-depth sound-design to production and from composition to performance has never been so simple. Manage your patches and easily import new presets and sound banks.
