Computer-Assisted Composition at IRCAM: From PatchWork to OpenMusic

摘要: In recent years, IRCAM has been exploring and developing software for computer-assisted composition (CAC). These packages allow composers musicologists to formalize experiment with the structures dynamics of musical languages. The Formes program (Rodet Cointe 1984), although primarily devoted control sound synthesis, was really a compositional environment high-level object-oriented architecture. Crime (Assayag, Castellengo, Malherbe 1985; Amiot, Assayag, Malherbe, Riotte 1986) first attempt at realize general CAC where user could define abstract formalisms. Francis Courtot developed CARLA as an use visual programming interface Prolog-based logic-programming system (Balaban, Ebcioglu, Laske 1992). development PatchWork environment, by M. Laurson, J. Duthen, C. Rueda (Laurson Duthen 1989; Laurson 1996), next stage in programs IRCAM. combination simplicity highly personal computing concept created infatuation among European diverse aesthetic backgrounds, including Antoine Bonnet, Michel Fano, Brian Ferneyhough, Gerard Grisey, Paavo Heininen, Magnus Lindberg, Claudy Tristan Murail, Kaija Saariaho, many others. OpenMusic, designed G. Assayag Agon Agon, Fineberg, Hanappe 1997; Delerue, 1998), is most environment. It CLOS, Common Lisp Object System (Steele 1990). Aside from being superset PatchWork, it opens new territories allowing composer visually design sophisticated object classes. introduces maquette concept, which enables material over time, revises language modern way.
