Abstract

This paper explores the use of perturbation in designing multi-performer or multi-agent interactive musical interfaces. A problem with the multi-performer approach is how to cohesively organize the independent data inputs into useable control information for synthesis engines. Perturbation has proven useful for navigating multi-agent NIMEs. The author's Windtree is discussed as an example multi-performer instrument in which perturbation is used for multichannel ecological modeling. The Windtree uses a physical system turbulence model controlled in real time by four performers.
