vorbei

vorbei is a program designed to generate a unique and complete piece of music every time it is run, and to do so with no external interaction. Each piece created by vorbei begins with the generation of a series of millisecond values known as a gesture, which provides the seed for all subsequent data and sound. Throughout a given run of the program, in order to reinforce emerging trends and encourage movement towards coherent structures, generated data is stored and analyzed to create probabilities that determine its later use. As such, individual runs of vorbei can be understood as a series of variations generated from increasingly extended derivations of the initial gesture.
