Texture Granular Synth 3.0 is a free instrument plugins featuring Asyncronous Granular Synthesis based upon the algorithm developed by Giorgio Nottoli.
It generates a grains’ flow in which the way each grain follows the other depends on probabilistic parameters such as grain density (attack/sec), overlapping, synchronism and fade of each grain.
The spectrum generated by the synthesis could be harmonic, expanded or contracted according to the value of frequency exponent parameter; the result will be a sound texture that can change from noisy fragmented sounds, to metallic and tuneless sounds such as bells, finally to harmonic sounds similar to strings or choirs.
Texture is available as a freeware instrument plugin for Windows and Mac (VST/AU).
