The PolyBrute 12 on the separately available Wooden Legs
Analog synthesizer from Arturia
With the Polybrute 12, Arturia is making a statement in terms of analog synthesizers. Based on the previous PolyBrute, Arturiadoublesthe polyphony from six to twelve voices and gives the optimized keyboard polyphonic Aftertouch including full MPE MIDI support. Twelve analog voices are pure energy, which is why there are five ventilation grilles on the extended front of the instrument to ensure sufficient ventilation. The twelve-voice instrument shines with two analog oscillators, two very different filters (Steiner-Parker and Moog-style), an extensive modulation matrix, sequencer and several effects. The pleasantly playable61-keykeyboard covers over five octaves, is velocity-sensitive and even has polyphonic Aftertouch (MPE). In terms of sound, the Polybrute 12 covers a wide range of classic analog sounds from the 70s to the present day. Thanks to the oscillators, which also offer mixable waveforms and of course do not lack the tried and tested Metalizer, the basic sound alone is both modern and timeless. The large keypad with 12 x 8 control elements fulfills different tasks depending on the mode. It is used to program the polyphonic sequencer, manage the stored sounds, assign the Morphing and set all modulation assignments. If you want to handle this storable flagship like a primal analog synth, simply activate Panel Mode; from then on, the sound will correspond to the current settings, regardless of what was previously in the memory location. Morphing is a real highlight of the PolyBrute 12. You can seamlessly crossfade between any two memory locations. Since there are enough sounds available with 768 presets, you could, for example, save a variant of a sound with different oscillator levels and/or modulation intensities and morph between these two presets. Or you can make this change between a percussive Bass and a pulsating pad sound; you can give free rein to your creativity.
Sound generation
The rich basic sound of the Arturia PolyBrute 12 is created with two analogue oscillators that generate the Metalizer, Pulse Width and Sawtooth waveforms in parallel. Metalizer is primarily a triangle waveform with wavefolder, which generates overtones with a metallic character as the value increases. Pulse Width is the classic square wave with pulse width modulation; the sawtooth more than fulfills its task; rich in overtones and powerful. Oscillator 2 also has a sub-oscillator. Oscillator FM and hardsync can be continuously adjusted between the two oscillators. Both tone generators and the tunable noise generator can be found in the mixer section, where the routing to the two filters is also defined for each signal source.
Filters
The color-coded filters are Steiner-Parker state-variable filters and 24dB Lowpass filters. The former is infinitely variable from Lowpass via Highpass to Bandpass and has the Brute Factor known from Arturia synthesizers as an additional parameter, which is basically a feedback circuit within the filter. The SVF has a very grainy sound with increasing resonance. The second filter is a classic 24dB Lowpass filter in the style of the Moog Ladder filter, which will be familiar to many from the Minimoog. The full and rich sound of the LPF is a classic of its kind in its own right. In addition, the second filter has a distortion and can be mixed continuously from serial to parallel in the signal path between the mixer and VCA using the Steiner-Parker filter. There is a master cutoff control with adjustable keyboard tracking for both filters. If you need the Tracking for the filters in detail, you can add this with a quick tap in the modulation matrix.
Modulation
You can see at first glance that no red pencil has been used here. In addition to the keyboard on the left-hand side of the instrument, an X/Y/Z touch controller (aka Morphée) adorns the control panel. X and Y implement finger movements up, down, left and right, Z reacts to pressure. All three can be assigned to any target, which enables expressive and lively playing of the sounds. The ribbon controller is located centrally above the keyboard and measures just over a third of the entire length of the device. The two intensity controls, which direct oscillator 2 to filter 1 and noise to filter 2, are permanently assigned. Two of the three loopable ADSR envelopes are permanently assigned to filters and VCA, but like almost all "generating functions" can be linked to other destinations. Thanks to the fader design, one can attest to this: Form follows function. The modulation sources are joined by three BPM-synchronizable LFOs. The first two each offer seven waveforms and can be monophonic, polyphonic or triggered. LFO 1 can be shifted in Phase and LFO 2 has an adjustable delay (fade in). LFO 3, on the other hand, can freely shape the waveform with Curve and Symmetry and can be switched to OneShot mode.
Effects
The effects section of the PolyBrute 12 consists of delay, reverb, EQ and modulation effects and can be switched either as an insert or send. The Delay is capable of BBD and ping-pong modes and can be synchronized to MIDI-Clock. The Reverb uses reverb, plate and others and covers a wide range from dark atmospheres to industrial halls to the "middle Grand Canyon". The modulation effects include chorus, ensemble and Phaser and provide wafting and floating sounds. In addition, a knob can be used to distribute the voices played in the panorama; a psychoacoustic blessing. :)
Attention recording!
Each sound memory of the Arturia PolyBrute 12 has a programmable, polyphonic sequencer track, which can be up to 64 steps long and can be provided with Shuffle and other playback modes. There is also an arpeggiator with extensive playback options and a motion recorder that can be used to record and automate parameters.
