Chaotic Substrate is an improvised multimedia work for digital audio and video. Based on the logistic map, the performer uses a MIDI controller to guide 256 sine oscillators through a predefined ‘score’ of frequencies. The navigation of this score: moving quickly or slowly, and moving forward, backward, or skipping around, allows for improvisation on a fixed set of frequencies that map to both the sonic and visual content of the work.
