The TaCEM project (Technology and Creativity in Electroacoustic Music), funded by the United Kingdom’s Arts and Humanities Research Council (AHRC), investigates the relationship between creative process and technological innovation on the basis of eight key works from the electroacoustic repertoire. A significant part of the dissemination of this investigation is in the form of software that embeds, on the one hand, interactive software tools to engage aurally both with the structures of the considered work and the technologies used and, on the other hand, filmed materials with the composer and, where applicable, her/his collaborators. This presentation demonstrates the software developed for pieces by two major figures of the developments of real-time electronics at Ircam, Philippe Manoury’s Pluton (1988) and Cort Lippe’s Music for Tuba and Computer (2008), and compares the aesthetic and technological aspects of these works and of their real-time performing environments.
