Creating an OSC Network Instrument with MaxMSP

networked_instrumentRecently in my class with Ali Momeni, we had an exercise surrounding the idea of a networked ensemble of computers. It turns out to be a fairly easy and effective technique. In a couple of hours we had fifteen computers all talking to each other by sending OSC messages over a wireless network. The messages could trigger a sinusoid at a specified volume and frequency, noise at a specified volume and duration, or one of five samples played at a specified volume and rate. The samples were selected and loaded locally, so only the OSC messages were being transmitted over the network.

By the end of the experiment all fifteen computers were producing chaotic mash-ups of randomly pitched sine waves, random white noise, and an eclectic collection of pitch shifted and/or reversed sampled sounds. Unfortunately I didn’t have a portable recorder on hand, but what I did do was capture the audio that was being generated from the messages that were being received on my laptop. Here’s an excerpt of what that sounded like. Now try to imagine that times fifteen. I’m also attaching the patch in case anyone would like have have a look. Just be aware that it was made quickly (I did clean it up a bit before uploading) and there’s a dependency on an external called ali.samplor that can be found here.

About John CS Keston

John CS Keston is an award winning transdisciplinary artist reimagining how music, video art, and computer science intersect. His work both questions and embraces his backgrounds in music technology, software development, and improvisation leading him toward unconventional compositions that convey a spirit of discovery and exploration through the use of graphic scores, chance and generative techniques, analog and digital synthesis, experimental sound design, signal processing, and acoustic piano. Performers are empowered to use their phonomnesis, or sonic imaginations, while contributing to his collaborative work. Originally from the United Kingdom, John currently resides in Minneapolis, Minnesota where he is a professor of Digital Media Arts at the University of St Thomas. He founded the sound design resource, AudioCookbook.org, where you will find articles and documentation about his projects and research. John has spoken, performed, or exhibited original work at New Interfaces for Musical Expression (NIME 2022), the International Computer Music Conference (ICMC 2022), the International Digital Media Arts Conference (iDMAa 2022), International Sound in Science Technology and the Arts (ISSTA 2017-2019), Northern Spark (2011-2017), the Weisman Art Museum, the Montreal Jazz Festival, the Walker Art Center, the Minnesota Institute of Art, the Eyeo Festival, INST-INT, Echofluxx (Prague), and Moogfest. He produced and performed in the piece Instant Cinema: Teleportation Platform X, a featured project at Northern Spark 2013. He composed and performed the music for In Habit: Life in Patterns (2012) and Words to Dead Lips (2011) in collaboration with the dance company Aniccha Arts. In 2017 he was commissioned by the Walker Art Center to compose music for former Merce Cunningham dancers during the Common Time performance series. His music appears in The Jeffrey Dahmer Files (2012) and he composed the music for the short Familiar Pavement (2015). He has appeared on more than a dozen albums including two solo albums on UnearthedMusic.com.
