José Echeveste (IRCAM) presents his lecture: Antescofo, A Dynamic Language for Real-Time Musician-Computer Interaction.
This talk focuses on programming time and interaction in Antescofo, a real-time system for performance coordination between musicians and computer processes during live music performance. To this end, Antescofo relies on artificial machine listening and a domain specific real-time programing language. It extends each paradigm through strong coupling of the two and a strong emphasis on temporal semantics and system behavior.
The challenge in bringing human actions into the computing realm is strongly related to the temporal semantics of the language and the precision of live execution despite heterogeneous nature of time in the two mediums. Interaction scenarios are expressed at a symbolic level through the management of musical time (i.e. events like notes or beats in relative tempi) and of the ‘physical’ time (with relationships like succession, delay, duration, speed). The Antescofo approach has been validated through numerous uses of the system in live electronic performances in contemporary music repertoire by various international music ensembles.
Antescofo language features will be presented through a series of real-world music examples which illustrate how to manage execution of different musical processes and their interactions with an external environment.
