Computer-aided Composition of Musical Processes

We present the formal model and implementation of a computer-aided composition system allowing for the composition of musical processes'. Rather than generating static data, this framework considers musical objects as dynamic structures likely to be updated and modified at any time. After formalizing a number of basic concepts, this paper describes the architecture of a framework comprising a scheduler, programming tools and graphical interfaces. The operation of this architecture, allowing to perform both regular and dynamic-processes composition, is explained through concrete musical examples.
