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.

Ring Modulated Rhodes Line Out of Context

Posted on January 17, 2009 by John CS Keston

While sorting through dusty clips from live performances I came across an angular Rhodes line that sounded quite odd removed from the context of the original set.

I decided to loop the line to create a forty second phrase. Afterward I ran it through distortion, ring modulation, reverb and delay. I also automated the fine tuning setting on the ring modulator to create a sweeping pitch shift.

Happy Anniversary Audio Cookbook

Posted on January 16, 2009 by John CS Keston

I registered the AudioCookbook.org domain in December 2007, but the first few entries on the site happened on January 14, 2008, which I am hereby declaring as the birthday of ACB making it one year old as of Wednesday. It has been an interesting year. In July, 2008 I started the One Sound Every Day project. Creating at least seven sounds a week with written accompaniment has been at times exhausting and exhilarating. Regular readers, commentary and contributions from around the globe have kept it fun and inspiring for me along the way. Thanks to sponsorship from Unearthed Music, who provide the hosting for ACB, we are non-profit and free of advertisements.

I would like to thank all the readers / listeners who have set their eyes / ears on ACB. A special thanks goes out to everyone who has commented, either with words or sound, keeping the discussions alive. A very special thanks goes out to the contributors including Simone Giuliani, Michael Koppelman, Nils Westdal, Leafcutter John, and Tom Player. I’d also like to thank Peter Kirn for helping to legitimizing ACB on his site Create Digital Music. Here’s a link to one of Keston and Westdal’s most popular tracks from the late nineties, Sonny’s Cut, off of our first album, Super Structure Baby.

Resonant Drone

Posted on January 15, 2009 by John CS Keston

Here’s another example of audio that was recorded for the purpose of live looping during a performance.

The clip is dated from August 18, 2006 and is a typical example of how I often use a resonant drone with cutoff frequency manipulation through delay to create textures.

Warbled Delay Trails on Korg MS2000

Posted on January 14, 2009 by John CS Keston

I came across this sample from a performance on July 13, 2006. It is a delayed synthesizer line that I played and captured as a clip in Ableton Live during the show. What’s interesting to me about this clip is the obvious modulation in pitch on the delay trails. This is not something that I programmed into the patch and I suspect is actually caused by a bug in the Korg MS2000. It’s possible to recreate this bug by enabling tempo delay then sending external sync to the instrument. I rarely experience this glitch anymore because rather than using the delay on the Korg, I usually run it through tempo delay in the software. However, I kind of like the ghostly quality it creates in this short passage.
