In this article, the author presents an overview of a historically pertinent electroacoustic device, one that has established and influenced many technological developments and compositional practices in the field of electroacoustic music - the UPIC (Unité Polyagogique Informatique du CEMAMu) system. This is a complex system of computers and peripherals designed to facilitate direct user access to sound and musical material. The focal point of the system is a graphics tablet on which the user draws; this drawing is then transformed into sound by the computer.
