Max Evo Devo Music (2006) 

An environment created in MAX for generating developmental biology inspired music

Evo-Devo Music is a MAX environment developed by Anna Lindemann for generating developmental biology-inspired music. Different musical motifs/fragments act as musical genes that can be turned on or off in different tissues of the musical organism as determined by the musical developmental regulatory hierarchy. The piece unfolds as a survey of the organism from top to bottom.

Each musical gene can have as input a musical motif with pitch, velocity, duration, and midi channel information. This musical fragment can then be modulated up or down, the rhythm can be expanded or contracted, different sections and amounts of the fragment can be inverted, different instruments can be invoked using different midi channels, and the fragment can be turned on and off. These varied modifications change over time as determined by the hierarchy of regulatory genes pictured in the diagram.
