About the computer-controlled multi-channel electric guitar:
Konrad Sprenger explores rhythmic patterns based on the Euclidean algorithm, to evoke a kind of cognitive insecurity through metrical dissonance. Sprenger approaches the strings of the guitar as frequency generators, tuned and set into motion by various electronically controlled mechanical actions.  The music relates to the insistent rhythms of Minimalism, Krautrock and Techno, and their shared focus on transcendence through propulsive, full-spectrum sound. The custom-built instrument was conceived by Konrad Sprenger, and realized by Sukandar Kartadinata and Daniel van den Eijkel.
