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.

Korg MS2000 Tempo Delay Effects

I created this synthesized effect using a Korg MS200 Analog Modeling Synthesizer. I often use this instrument with the external sync enabled for arpeggiation and and tempo delay processing. The delay does some strange things with the external sync enabled. As you adjust the delay time it jumps from different units of time within the tempo including triplets. This can produced some future dub, spaced out, synthethized effects when the feedback is up all the way.

Piano with Limiter, Chorus and Reverb

Here’s the piano from the last entry without the distortion applied. I left on all the other processing including limiting, stereo chorus and reverb. Now you can hear why I was not happy with the original recording. The recording is a bit noisey and although I used a nice mic (AKG c4000b large diaphragm condenser), the piano is quite old and suffers from a thin sound along with knocks and rattles that occur when using the keyboard and pedals. One might hear these features as the instruments character, but that rational only goes so far. I do like how limiting is manipulating the dynamics in the example. Adding the stereo chorus and reverb blends much of the rattling and knocks into the overall sound while the limiter expands the noise as the sound decays.

Piano Destruction

I recorded these gentle piano chords on March 25, 2008 while working on a classically influenced piece of music. While re-listening to this today I had the idea of damaging the recording as much as possible with processing to see what I might end up with. The main reason I decided to do this was because I was dissatisfied with the sound of the original recording and thought, perhaps I could get something interesting by degrading the signal significantly. I tried a few different types of processing but settled with heavy limiting followed by a high shelf into monster distortion, topped off with almost 5 seconds of reverb.

Electric Drill Sounds

Here are the original electric drill sounds from the Power Tool Percussion post, which I am presenting without any processing by request. The recording was made with a Shure VP88 stereo condenser microphone. I ran the drill at several different speeds while holding it still, and moving it around the mic to simulation motion.

Toward the end you can hear the stress on the motor as I drilled a few holes in a piece of wood. Although I have done lots of strange things to produce sound in my past, for some reason it felt really weird drilling holes in wood for no reason other than capturing the sound it made.

Handlebar Blow Pipes

I commute by bicycle daily and cycle for fun often as well, so I have lots of bike parts lying around that I should probably throw away. About a month ago I was hit by a car in the bike lane, but came out relatively unscathed. A few days later I realized my handlebars were slightly bent in the accident. After replacing them I decided to record some sounds I was making with the old ones. I chopped out the best samples and put them into an instrument so I could play them with a controller. I messed about with that for a little while then, just for fun, ran it through a long reverb. Here are the preliminary results.
