Introduction
Congratulations on your purchase of the Arturia PolyBrute!
PolyBrute is the logical progression of the Brute series of synthesizers. It inherits a decade
of development and refinement that began with the Micro- and MiniBrute synths, and later
thrilled the world with the release of the MatrixBrute. These synthesizers claimed new
territory through their power, elegance and simplicity. And the sound of those instruments:
fat, smooth, aggressive, unique... It seemed there was nothing a musician or sound designer
couldn't do if they had one or more of these beautiful Brutes in the studio.
But wonderful as they are, they are monophonic (mostly; the MatrixBrute has a three-
voice paraphonic mode). Speculation has run wild for years: Will Arturia make a polyphonic
analog synthesizer someday?
Yes, yes, yes, yes, yes, and proudly, yes. Enter the PolyBrute, with six killer analog voices,
two luscious filters, and much, much more:
• 6-voice polyphonic analog synthesizer with split/layer capability
• 5-octave, velocity-sensitive keyboard with channel aftertouch and adjustable
curves
• Continuous deep/subtle sound transformations through a global morphing
feature
• Poly, Mono, and Unison modes with selectable voice allocation
• Polyphonic sequencer and arpeggiator onboard
• Motion recorder captures the movement of one control for one-shot or looped
playback
• Mixer section can route oscillators and noise generator through one or both filters
• Portamento/Glide with continuous and chromatic options
• Built-in digital effects (chorus/phaser/flanger/ring modulator, delay, reverb)
• Effects can be used as insert or send effects, or bypassed for a pure analog
signal path
• Two independent displays aid navigation and provide visual feedback
• 768 patch memories, arranged in 8 banks of 96
• Snapshot: preserve up to 5 edits in progress, with instant recall
• A potentially infinite number of patches can be imported/exported with the
PolyBrute Editor
Voice engine
• Each voice has two oscillators, plus a sub-oscillator for VCO 2
• Powerful waveform sculpting features, such as variable oscillator sync,
wavefolding (i.e., Metalizer)
• Two independent filters per voice
◦ Steiner: 12dB per octave (continuous multimode), plus our famous
Brute Factor for extra grit
◦ Ladder: 24dB per octave with distortion
◦ Use them in series, parallel, or any blend of the two
◦ Master Cutoff control to sweep both filters at once
◦ Filter FM (VCO 2 > VCF 1, Noise > VCF 2)
• Continuous soft > hard oscillator sync (2 > 1)
• Morph: Every patch has two sounds (A+B); most parameters can morph between
an A and B setting. Details are here.
• Three syncable, multi-waveform LFOs per voice
• Three loopable envelopes: VCF/VCA (ADSR), Mod (DADSR)
• Multi-colour noise generator
