Multi-scale design of interactive music systems : the libTuiles experiment

Abstract : The design and implementation of an interactive music system is a difficult task. It necessitates the description of complex interplays between two design layers at least : the real time synchronous layer for audio processing, and at the symbolic event based layer for interaction handling. Tiled programming is a recent proposal that aims at combining with a single metaphor: tiled signals, the distinct programmatic features that are used in these two layers. The libTuiles experiment presented in this paper is a first experimental implementation of such a new design principle.
