Arturia's PolyBrute arrived in 2020 as the company's answer to a question many analog synth players had been asking: what if you could play full chords on a proper analog polysynth without spending the price of a used car? Six years in, it's proven itself as a genuinely capable instrument that doesn't compromise on the analog character that made Arturia's Brute series beloved in the first place.
The PolyBrute is built around six voices of true analog polyphony, each with two voltage-controlled oscillators that generate saw, triangle, square with pulse width modulation, and a sub-oscillator. The oscillators include a metalizer for waveshaping and support linear FM and hard sync, giving you plenty of harmonic manipulation before the signal even hits the filters. You get two filters per voice: a 12dB Steiner-Parker multimode filter that morphs continuously between lowpass, notch, highpass, and bandpass modes, plus a 24dB ladder filter with distortion. Three envelope generators and three LFOs with tempo sync and various retriggering options handle modulation, while a 12x32 modulation matrix lets you route modulation sources to 32 target parameters without patching cables. The 61-key keyboard features velocity and aftertouch sensitivity, and the instrument includes a Morphée 3D controller, wooden ribbon controller, and built-in digital effects covering modulation, delay, and reverb algorithms. A 64-step sequencer with automation tracks and an arpeggiator round out the feature set.
The PolyBrute has earned solid respect in the community for delivering genuine analog warmth and expressiveness at a price point that makes polyphonic analog synthesis accessible. Players appreciate the sound morphing feature that lets you interpolate between two preset configurations, the intuitive modulation matrix that eliminates cable clutter, and the overall build quality. Some users note the learning curve on the matrix can be steep for beginners, and a few have wished for more preset storage, but these are minor considerations given what the instrument delivers sonically.
