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.

Synthesizer Fifths Drone

I added some delay to spread the stereo spectrum on this synthesizer drone of a low frequency fifith interval. During the recording you can hear the cutoff frequency changing as I turned the knob for it. On my most often used synth, the Korg MS2000 that was used for this recording, the surface around the cutoff frequency knob has been polished smooth from wear. I use it much more frequently than the modulation wheel or pitch wheel. I love knobs.

Travel Glide

Here’s a snippet from a piece I started composing on March 28, 2007. I don’t remember exactly how I created the sounds other than the instruments that I used (Rhodes and Korg MS2000) and some of the processing applied (too many to name), therefore I don’t have a lot to say about this piece, other than:

1. It’s unfinished
2. It uses a variety of processing
3. I don’t know why I called it “Travel Glide”
4. There is no obvious significance between the image and the composition

Pianica

I bought this instrument for a bargain price at a music store quite some time ago. It’s an inexpensive Japanese made version of a melodica. They sound a lot like harmonicas, but has a keyboard to play the notes. Hohner makes the most popular versions of this instrument, but I really like the gravelly tone of this one that I recorded during a session on August 2, 2006.

Electric Razor

In January, 2008 I wrote about the sound design I had produced for an animated short film called “Drown” (43mb – right click to download the movie) by Aaron Dabelow. In that entry I illustrated how I created ambiance for the underwater atmosphere of the piece. Here’s a recording of my electric beard trimmer. I used it to create the sound for the mechanical humming bird like creatures in the film at about 1:08 minutes.

As I was recording I moved the beard trimmer past and around the mic to simulate the movement of the creatures, which use high speed rotary fans for locomotion. Once I synchronized the the audio to the animation it seemed to fit quite well. As you can see, it’s probably about time that I stopped recording electric razors and started using them on my face.

Automated Auto Pan

As a producer, a technique I have found that is an effective way to develop the dynamics of a performance is by adding expression through automated processing. In this phrase of synth from a composition that I’m working on I have applied automation to add an expressive quality to the recording.

I have always been fascinated by the Doppler effect as it is mechanically applied to sound through the use of Leslie speaker cabinets. I own a Leslie cabinet that I had modified so that I was able to run instruments through the amplifier, other than Hammond organ, and control the speed with a foot switch. My goal was to play my Rhodes through a Leslie, and this is something I did during live performances for years to come.

My favorite characteristic of the Leslie is the slowing down and speeding up of the motors that control the speaker rotation. This can be simulated quite well with plugins or virtual instruments such as the Native Instruments B4. In this example, rather than use Leslie simulation, I opted to simply automate the “Rate” parameter in Live’s Auto Pan effect. Leslie simulators often add other characteristics like motor noise, filtering and distortion, but I wanted to keep the signal relatively clean while still getting a speeding up and slowing down expressive quality to the instrument. To get the full effect of the automated panning, listen with headphones firmly planted on ears.
