•Create rich, energetic and detailed bitcrushed textures. •Explore a wide range of tones, from refined, graceful characters to glitchy mutilated mayhem. •Animate your tracks with dynamic audio-chopping and expressive modulations. •Enjoy the straightforward, elegant design in your new and powerful bitcrush effect. Control whether the whole signal or a specific frequency range is affected using a Low-Pass, Band-Pass or High-Pass filter. Refine it further with 'Cutoff' and 'Resonance' control. Slash the rate of samples taken from the incoming audio down to 10hz, reduce unwanted sampling errors using the Nyquist filter and refine the sampling shape with the smoothen control. Crush the resolution of the audio down to a single bit, use the range booster to exploit all available bits and structure the chaos using the envelope to shape the original dynamics of the incoming signal. Mangle your tracks into digital disorder; use the Threshold to time the trigger, Time & Num Repeats to shape your repetitions then have them fade away using the Decay.
