Arturia's analogue mothership

The Arturia PolyBrute 12 builds on the expressive architecture of the original PolyBrute, expanding it into a flagship analogue polysynth focused on articulation as much as sound design. Retaining the dual-oscillator architecture, Steiner-Parker multimode and ladder-style low-pass filters, and deep modulation matrix, it doubles its sibling's polyphony to enable richer layers, wider splits, and more natural polyphonic playing. The defining evolution of the PolyBrute 12, however, lies in the new FullTouch keybed with polyphonic aftertouch, MPE support, and continuous control over each note's movement. The morphing architecture still allows seamless transformation between two fully realised sound states, brought to life through the Morphée controller and direct performance interface – with ribbon control, assignable performance tools, and flexible routing expanding the synth's role across studio and stage environments.

Architecture and polyphony

The PolyBrute 12 retains the analogue architecture of its predecessor, centred on dual oscillators per voice with Metalizer wavefolding, PWM, and linear FM. Signals pass through a dual-filter section combining Steiner-Parker multimode and ladder-style low-pass designs, maintaining its established tonal range. The 16×32 modulation matrix continues to provide extensive routing possibilities, enabling complex interactions without sacrificing immediacy. With twelve analogue voices now available, Split and Layer configurations gain greater headroom, unison modes become more expansive, and dense chords can unfold naturally without voice limitation. Rather than altering the core sonic character, the expanded polyphony enhances its practical range, allowing richer textures and more fluid polyphonic performance while maintaining the instrument's analogue identity.

Performance and creative tools

The Arturia PolyBrute 12 expands the performance concept of the original through its FullTouch keybed, introducing polyphonic aftertouch, MPE support, and new articulation possibilities that transform how sounds respond to touch. Each note can evolve independently, for subtle tonal shifts, dynamic swells, or expressive modulation within chords rather than across the entire keyboard. Combined with the morphing system, Morphée controller, ribbon, and assignable performance controls, the instrument encourages continuous interaction rather than static playback. Through the modulation matrix, these controls allow gestures to be mapped to multiple parameters simultaneously in real time. A polyphonic sequencer with automation and a versatile arpeggiator help generate evolving patterns and live experimentation, reinforcing the PolyBrute 12's identity as a performance-focused analogue flagship.

About Arturia

Arturia's success story began with software emulations of well-known analogue synthesizers such as the Moog Minimoog, Sequential Prophet-5, and Oberheim SEM. The popular software instruments included in the V Collection are still flagship products of the French developer today. Over time, Arturia has gradually expanded its range and now also offers a host of hardware devices, ranging from synthesizers and keyboard controllers to sequencers – so that the former software developer has also become a household name in the world of analogue synthesizers and other equipment.

Workflow and studio integration

The Arturia PolyBrute 12 adapts confidently to both studio production and live performance environments. Single, Split, and Layer modes benefit from the expanded twelve-voice architecture, making complex voicings, layered textures, and performance-oriented keyboard setups more natural in practice. The built-in polyphonic sequencer records notes alongside parameter movements, while the arpeggiator introduces synchronised rhythmic variation for evolving compositions. USB and MIDI connectivity allow direct integration with DAWs, supported by the PolyBrute Connect software for detailed editing, automation, and preset management. Stereo outputs, analogue clock I/O, and multiple pedal inputs facilitate integration into hybrid rigs, from modular systems to modern production setups. Rather than simply increasing polyphony, the PolyBrute 12 refines the workflow of its predecessor, combining expressive depth with practical flexibility across stage and studio contexts.

Endlich 12 Stimmen
Teilnehmer_ 29.11.2024
Der PB 12 ist mit einem Waldorf Iridium und einem Hydrasynth Deluxe das neue Herzstück meiner Klangerzeugung. Hier die ersten Eindrücke:

Gehäuse und Layout:
Das Gerät ist groß und schwer, Verarbeitung ist gut. War jedoch etwas enttäuscht, dass das Teil Made in China ist. Die Optik ist Geschmackssache. Axel Hartmann hat schon schönere Geräte designt. Die Farbe ist ein Cremeton mit einem Hauch rosa. Nun ja. Wollte nicht warten, bis (eventuell) eine schwarze Variante herauskommt. Hätte mir eine mittigere Platzierung des Displays näher an der Tastatur gewünscht.
Ein Hinweis: Das Gerät ist am Gehäuse unterhalb der Tastatur abgeschrägt. Das hat zur Folge, dass eine Platzierung bei vielen schräggestellten Keyboardhalterungen nicht möglich ist.

Sound:
Der Klang ist sehr gut, fertig. Von warm und schwer bis hin zu metallisch-schneidend - überzeugend, mit schönen Obertönen. Modulationsmonster. Da analog, etwas mehr Rauschen und Nebengeräusche im Vergleich zu modernen Digitalgeräten. Sehr gut klingende Effektsektion.
Mit Wheels, Morphee, Ribbon-Controller, Polyaftertouch, MPE und drei Pedal-Anschlüssen extrem viele Ausdrucksmöglichkeiten.
Die 12 Stimmen sind bei bitimbralem Betrieb absolut notwendig. 6 Stimmen wie beim normalen P-Brute sind mir zu wenig. Hier vermisse ich ein zweites Paar Outputs.

Fazit:
Trotz ein paar Abstrichen tolles Teil.

Un Synthé vraiment au top
YMAR 02.12.2024
Le Polybrute 12 est tout simplement exceptionnel ! Ce synthétiseur offre une qualité sonore et de fabrication irréprochable, qui saura satisfaire les musiciens les plus exigeants. Ce qui le distingue de la concurrence, c’est son workflow innovant, à la fois avancé et intuitif, permettant une prise en main rapide. Mention spéciale pour son intégration fluide avec un DAW comme Ableton Live, une rareté pour un synthétiseur analogique de cette gamme. Un véritable bijou pour les amateurs de sons analogiques et les professionnels en quête de flexibilité dans leur configuration studio.

Monster!
neuronist 24.10.2024
Ich bin begeistert vom Polybrute12! Klingt super, enorm deep, tut genau was er soll. Es gibt so die Leute, die meinen, er klänge dünn ohne Effekte, aber mal ehrlich - wo hat man keine Effekte drauf? Finde ich albern, mit Effekten klingt er phantastisch und er passt sich einfach besser in Mixe ein so. Dicke fette Analoge, die einem die Ohren wegblasen und man kaum im Mix unterbekommt habe ich allerdings genug, da war das nicht die Priorität. Was der Polybrute wirklich unfassbar gut leisten kann ist ambience durch seine vielen Möglichkeiten den Sound zu modulieren (auch live). Ich finde auch im Mix klingt er wirklich dick genug!
