Ramus

(2009)
solo instrument, live electronics & interactive video
performance by Ulrich Maiss in Providence, RI, 2011
Ramus' audiovisual processing is based on a simple branching process: individual elements taken at the start of a phrase are split repeatedly, building up in structure until a new phrase resets the electronics. Visually, the input is a single dot, which builds into more complex shapes through splitting and multiplication, filtered by the music. The audio stems from live samples taken at the beginning of phrases, split using pitch shifters and progressively filtered. Large-scale changes in the visual processing dictate different sections for the improviser, acting as a rough score for the performance.
