This Max/MSP patch uses cellular automata (or CA) to provide amplitude information for an array of sine-wave oscillators that can be set to cover a set of frequency bins, creating some interesting & creative algorithmic timbres.
This simple use of CA for audio production is similar to a very basic form of compositional CA mapping, known as 'piano-roll'. In this case, the frecuencies are (by default) harmonically related partials of a base frequency, provided by a MIDI input device. For this reason, the CA is responsible chiefly for the timbre, where the MIDI compositional material is left to other means.
Cellular Automata was brought to my attention by Max/MSP, and further researched in Eduardo Miranda's book ' Computer Sound Design'; quickly becoming the focus of my dissertation, and inspiring my work in algorithmic composition.
