Divertimento Ritmico for Two Synthesizers , Two Locations, and One Acoustic Network of Four Channels by Net vs. Net (Juan-Pablo Cáceres @ Center for Computer Research in Music and Acoustics (CCRMA) & Alain Renaud @ Sonic Arts Research Centre (SARC)) :: November 9, 2007, 8:00 (PST) pm, CCRMA Stage, Department of Music, Stanford University, Stanford, CA :: and Sonic Arts Research Centre, Queen’s University Belfast, Northern Ireland.
This piece is a structured improvisation that explores multi-channel feedback delays on the network. The delay path between Stanford (California, USA) and SARC (Belfast, Ireland) is used as a variable feedback comb filter for each of the four channels. The rhythmic meter of the piece follows this delay path as a way of synchronization / a-synchronization between the two performers. Echoes move on a space embedded on the network path. A custom visualization tool shows the activity of the musicians on each location and also cues the different parts of the piece. We use Jacktrip, SuperCollider, Processing and The Network.
Net vs. Net is a collective of musicians exploring the potential of high-speed networks as a real-time performance medium. Founded by Juan-Pablo Cáceres and Alain Renaud, it takes its inspiration from the comic strip “Spy vs. Spy” as a metaphor of the “delay battle” that happens on the network between two or more geographically displaced musicians.
