Temporal objects for the design of reusable library in Antescofo

Composers develops their own idiosyncratic compositional language through their pieces. In addition, composers and sound engineers have to face drastically different performance set-up for the same piece. This situation advocate for the development of new generic mechanism to simplify the development of generic yet dedicated libraries in Antescofo. In cooperation with various composers (Marco Stroppa, Julia Blondeau, Jason Freeman, Jose Miguel Fernandez, Yann Marez) we have introduced seevral new mechanisms in Antescofo to ease the building of dedicated yet reusable library of compositional pieces: extnesion of the functional language to include new control structure, introduction of continuation combinators making possible to start actions at the end of other durative actions, marshalling of Antescofo values, etc. The most notable ones are actor-based features to implement temporal objects. Object templates are specified and then instantiated at will. A temporal object encapsulate a local state; it can react to logical condition; it offers instantaneous as well as durative methods; reaction to synchronous broadcast can be defined as well as exceptional condition handlers. These new features are currently tested in the development of new pieces and are expected to evolve following the feedbacks from these applications.
