BLEASS Granulizer is an innovative granular effect processor crafted for musicians, producers, and sound designers who want to transform incoming audio signals into rich, evolving textures and immersive soundscapes. It works by slicing audio inputs into small "grains" and reassembling them through real-time modulation of different parameters that you can visualize thanks to a 3D visualizer: Modulate - Volume - Pan (represented by width in the visualizer) - Size ( = grain’s duration) - Density ( = frequency of grains generation) - Offset ( = the amount of time between record and play represented by the depth in the 3D visualizer) - Backward/Forward Playback Direction - Shape ( = grain’s envelope, represented by the height dimension in the visualizer) - Warmth ( = strength of the distortion applied to the grain) - Tune ( = grains can be pitched up or down according to different modes: “Fine” / Chromatic / Major / Minor / 5th / Major 7th / Minor 7th / Octave. The amount of randomization can be set with the “dice” knobs. Density, grain size, and offset range can be freely synced or beat synced to the host’s tempo. Touching and holding the visualizer modifies pan and density. BLEASS Granulizer takes up to 4 sources from different busses as inputs (compatible host required such as AUM). When multiple busses are on, each grain is randomly extracted from one of the available sources. BLEASS Granulizer is your unique granular texture effect for reshaping any audio source into a dynamic granular soundscape in ways you've never imagined.
