WolframTones: An Experiment in a New Kind of Music
WolframTones works by taking simple programs from Wolfram's computational universe, and using music theory and Mathematica algorithms to render them as music. Each program in effect defines a virtual world, with its own special story. WolframTones supports multiple instruments, as well as percussion. Everything is always derived from a single underlying cellular automaton pattern. But different instruments can be set up to pick off different aspects of the pattern--say to correspond to a melodic line or a bass track. WolframTones also supports a number of algorithms for deriving percussion from cellular automaton patterns. via tones.wolfram.com
