Addac's latest module, the Stochastic Voltage Generator, has inspired me to delve into the eccentric history of stochastic (or aleatory or chance) music, from Mozart to Marcel Duchamp, John Cage, Morton Feldman, and Iannis Xenakis -- and from Buchla, Moog, and Arp to Eurorack. The accompanying patch is inspired by Feldman's graphic scores (especially the early "Projections" scores).
