Cosmos Saturn7 is the engineer of sound art, the ultimate answer to computer aided sound design. Cosmos is a real-time dynamic stochastic synthesis engine, which does generate complex sonic textures with various event distribution processes. Discrete sonic events of certain density are distributed in a time space with their onset time and duration parameter calculated with stochastic /deterministic functions. Each macro event defines the duration of a meso space, and the sub events are distributed inside it. The event distribution engine of Cosmosƒ is a hierarchical embodiment of multiple time scales.
