Abstract
This paper describes a MIDI instrument for the generative
composition of polyrhythmic patterns. Patterns are determined
by the activation of cells in a non-homogeneous set of interconnected cellular automata grids which form the faces of a cube
in virtual three-dimensional space. This paper discusses the
selection of the rules of the cellular automata which enable
rhythmic outcomes to be generated by the system, and the
motivation for organizing the cells in their current configuration.
The fluid sonification and visualization of the cellular automata
arrays was a specific aim of this work for gallery installation.
Hence the means by which the rigidly-defined and deterministic
automata behave was intended to be visualized and sonified in
such a way as to convey a sense of emerging liquidity from the
mechanism. A brief discussion of these issues appears in this
paper.
