Nodewebba: Software for Composing with Networked Iterated Maps

Nodewebba software provides a GUI implementation of the author’ s “Variable-Coupled Map Networks” (VCMN) approach to algorithmic composition. A VCMN node consists of a simple iterated map, timing controls, and controls for mapping the node output to musical parameters. These nodes can be networked, routing the outputs of nodes to control the variables of other nodes. This can enable complex emergent patterning and provides a powerful tool for creating musical materials that exhibit interrelated parts. Nodewebba also provides API hooks for programmers to expand its functionality. The author discusses the design and features of Nodewebba, some of the technical implementation issues, and a brief example of its application to a compositional project.
