Arturia PolyBrute Analog Morphing Matrix Synthesizer Bundle with Piano Bench (Black, Small)

$ 2,499.00

The Arturia PolyBrute is a powerful 6-voice polyphonic analog synthesizer with powerful morphing capabilities and multi-axis performance controls for next-generation musical expression. The PolyBrute is designed for music producers, sound designers, performing musicians, or anyone looking to explore sound in perpetual motion. The morph function allows a sound to exist in two states (A and B) within a single preset, with seamless morphing between them. In fact, you can copy any A or B component of a preset to what you are currently editing, making for fast and easy sonic transformations. Coupled with the Morphee three-dimensional performance touchpad, and you've got intricate morphing expression right at your fingertips. Manipulate any facet of PolyBrute's sound, from delicate morphing to extreme dynamic shifts, across the X, Y, and Z axis in an instant.The PolyBrute's architecture starts with two Brute waveshaping oscillators capable of a wide pallet of timbral versatility. Both oscillators generate three basic waveforms (sawtooth, triangle, and square with pulse-width control), which can be mixed creating unusual and harmonically rich tones. Anything can be created from airy pads to snarling bass riffs. VCO2 also includes a sine wave sub-oscillator that runs an octave below the fundamental pitch. There are various FM capabilities as well as hard- and soft-sync options creating even more dynamically diverse tones. Additionally, a noise generator can be added to the mix and features a knob for dialing any color from red noise with its darker rumble to white noise with its crisp, multispectral character.

The filter section sports a continuously variable 12 dB Steiner Parker filter with low-pass, high-pass, and bandpass, and a classic 24 dB low-pass ladder filter with gain compensation, which prevents the reduction of lower frequencies that accompany higher resonance levels. Filter 1 includes the famous Arturia Brute Factor feedback filter for warming up the low end and producing monster growls, while the distortion circuit of Filter 2 controls the ladder filter's feed into the VCA.There are three envelope generators including dedicated ADSRs with velocity for the VCF and VCA. The third envelope is freely assignable to any parameter in the matrix and includes a delay before the ADSR section. Additionally, there are three LFOs for adding modulation to any parameter. LFO 1 and 2 offer sine, triangle, square, down-sawtooth, up-sawtooth, sample-and hold, and slewed random waveforms. LFO 1 features a Phase control, which adjusts where the LFO wave cycle starts, while LFO 2 features Fade In, which offsets the start of LFO2 and fades it in gradually. LFO 3 offers a sweepable LFO waveshape from logarithmic to linear and finally exponential. If that weren't enough, each LFO can have its own sync division setting, allowing for independent binary, triplet, or dotted options.
