Iscore: a system for writing interaction

In this article, we present the development of research carried out to design a system of interactive scores for composition and execution, based on temporal constraints called Iscore. This system has been designed in order to allow musicians to interpret pieces of electro-acoustic music but since it uses a symbolic representations of the scores, it can bee seen as a system for more generally writing interaction with a temporal approach. Then, numerous other applications could be possible. This system can be used to create interactive multimedia scenarios (for theater shows or museum visits as examples) and also for adapting musical pieces or interactive multimedia documents for mutli-player applications or players with limited ability.

Interactive scores: A model for specifying temporal relations between interactive and static events

Abstract We propose a formalism for specifying temporal relations between interactive triggerings and releasings occurring during performance of written musical pieces. Temporal durations are specified between parts or notes of a written piece. Then, we proceed to a static analysis of the piece in order to produce a program providing safe execution of the piece according to the temporal relations.

Un format de partitions interactives

Nous presentons dans cet article un format XML cree pour coder les partitions interactives generees via le systeme Iscore. Le developpement de Iscore est l’aboutissement de travaux de recherche menes au LaBRI en collaboration avec l’Ircam, visant a aboutir a un systeme de partitions interactives pour la composition et l’interpretation, base sur des contraintes temporelles. La question du format de sauvegarde des documents edites au travers de ce systeme s’est rapidement posee et devant les evolutions recentes vers les technologies XML, nous avons decide d’y repondre par la redaction d’une DTD (document type definition). Pense a la base comme support pour le systeme de sauvegarde de Iscore, ce format pourrait egalement servir d’interface avec d’autres formats XML et participer a l’elaboration d’un format general de partitions numeriques.
