Time, Timelines and Temporal Scopes in the Antescofo DSL v1.0

This paper presents the model of time developed in the ver- sion 1.0 of the Antescofo system. Antescofo integrates a listening module with a dedicated reactive and timed real- time programming language used to define the electronic actions to be performed in sync with a human performer. Since its beginnings, the model of time supported by the DSL has been developed and enriched, going from implicit relationships to denotable entities in v1.0. This paper fo- cuses on the simultaneity and succession relationships that organize actions on a timeline, the creation of multiple in- dependent timelines and on the notion of temporal scope that defines how time passes on a timeline relatively to the occurrence of events and to the fluence of another time- line. Temporal scopes offer generic and expressive ways to “play in time” the electronics with a human performer.
