Chamagne is a pianist who gradually migrated towards improvised music in the 1990s while developing electroacoustic instruments that mix analogical and digital synthesizers, prepared sound objects, and computer program Max that allows for real time manipulation of data, images, and sounds. Since 2006, Chamagne has been a member of the data-processing group, GMEA (Groupe de Musique Electroacoustique d’Albi at the Centre National de Création Musicale) where he develops new interfaces for the real time control of sound synthesis and spatialization. He creates multimedia performances which combine theatre, cinema, poetry, dance, visual art, and improvised music. Through experimentation and the development of innovative/interactive devices he creates, explores, and questions the direction and role of the musical gesture in the live interpretation of electronic music, blurring the lines between composition, interpretation, and improvisation. He is famous in France for his development of the multimedia “Aperture”, a frame with built in sensors that allows musicians to control electronic and recorded sound through physical gesture.
