Graphical GROOVE: memorial for the VAMPIRE, a visual music system, (ed.) Laurie Spiegel , exh. cat. Organised Sound (1998)

»was an instrument for composing abstract patterns of change over time by recording human input into a computer via an array of devices the interpretation and use of each of which could be programmed and the data from which could be stored, replayed, reinterpreted and reused. The set of time functions created could be further altered by any transformation one wished to program and then used to control any parameter of image or of sound (when transferred back to GROOVE’s audio-interfaced computer by computer tape or disk). Unfortunately, due to the requirement of separate computers in separate rooms at the Labs, it was not physically possible to use a single set of recorded (and/or computed) time functions to control both image and sound simultaneously, though in principle this would have been possible.«
