a bold new chapter in the story of synthesis

Imagine being able to sweep all the parameter settings between two different patches all at once. PolyBrute goes even further with each preset existing in two states simultaneouly - A and B - and the groundbreaking ability to gradually morph between them.


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.

tour de force

To complement its sonic power and colossal flexibility, we knew we wanted PolyBrute to have every conceivable means of performance expression. The single morph knob is the key that unlocks PolyBrute’s sweeping morph abilities - but it doesn’t end there.

The innovative 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 the spectrum.

The Keyboard

Coupled with a premium velocity/pressure-sensitive keybed, pitch wheel and assignable mod wheel, and footpedal controller inputs, and PolyBrute excels beyond the realm of powerful polysynth.

Dual iconic filters

Add color and shape to your timbres with two classic filter designs, configurable in series, parallel, or continuously variable.

A timeless 12db/octave filter with continuous slope type, enhanced with the signature Brute Factor feedback for bite & bark in equal measure.

The Ladder

The legendary 24db/octave filter for that essential low-pass smoothness, supercharged with distortion to compliment the Brute voice.
