I am interested in using "cellular automata" for creating musical structures – and Stephen Wolfram is one of the main explorers of these mathematical "entities": rule based mathematical systems with discrete states which can generate very complex patterns from a few simple rules like the famous "Game of Life" algorithm.
So my basic pattern is the "entry pattern" of a system of f. e. 16 states. The step event-function is the "rule" which changes the states of the system. with another step event on pitch I create another "dimension of change" With another step event on direction and/or on amount I actually create a "meta-rule" because the rule "or the way change happens" is changed by another rule…..
I know this is not at all important for composing nice and interesting music – or it is??? – so it’s perhaps bit OT.
