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.

Experimental Music Mondays Part 2

This Monday, March 29, 2010 is the second installment of Experimental Music Mondays curated by John Keston. The line-up this time includes Pawlic (Jesse Pollock) and Terr the Om (Nathan Brende).

Sandwiched between them is Ostracon. This is the name I’m using for the plural version of Ostraka. This instance involves the usual characters, John Keston (aka Ostraka), Graham O’Brien, and the addition of Oliver Grudem who will be interjecting his enigmatic imagery as an input source for the generative musical phrases produced by the GMS.

The venue is the Kitty Cat Klub, 315 14th Avenue SE, Minneapolis, Minnesota. The music starts at 9:00pm.

Sequential Circuits Pro-One Restoration Part 2

Although I had seen photos of the Rev 1.2 mushrooms (mine was made prior to Rev 1.2), I didn’t expect to see Chenrezig, the Tibetan Buddha of Compassion, silk screened onto the circuit board of my Sequential Circuits Pro-One, or the Buddhist mantra, “Om Mani Padme Hum”, etched into the board in Tibetan characters. Even better, Sequential Circuits founder and MIDI pioneer Dave Smith initialed the circuit board twice in the upper left hand corner.

I should mention that this is my second Pro-One. The first one was stolen, and I bought the second one to replace it since I needed that exact sound for the band I was in at the time. The new one was missing a mod wheel. Later one of the knobs was broken off at a show or studio session, so I’m pretty excited to have it restored to it’s former glory.

Checkout the gallery to see the photos of the restoration process. The second and final session of the restoration happened the moment I received the missing parts. These included a replacement modulation wheel (although I think it turned out to be a pitch wheel), a replacement potentiometer, and a missing knob.

The first thing I did was install the mod wheel. Then it was time to swap out the broken pot. I had to remove the circuit board to do this, so while I had it out I thought it would be a good idea to clean things up a bit, so that was the majority of time spent. Finally I removed the old pot, replaced it, and reassembled everything, cleaning things up along the way. Before I put all the screws in I gave it a quick listen to make sure it still worked and the new parts were functional. It was an evening’s work, but more like fun to be honest. Enjoy the pics.

Four Oscillator Drone Produced with the WSG


What good is a Weird Sound Generator if you’re not using it to make weird sounds? Sometimes it is nice to just hold it on your lap and stroke it gently. That aside, it’s quiet useful once you plug it in and start twiddling the knobs. Here’s a piece I created by tuning the each of the four oscillators on the WSG and then fiddled with the filters. At the same time I made some adjustments to a phaser that I was running it through in Ableton Live and topped it off with ping pong delay.

WSG Build Gallery


I’ve created a slideshow that illustrates the process of building my Weird Sound Generator, from the unopened box through completion of the project. The third photo in the series (shown below) shows the items that came out of the box including all of the components for the WSG and a CD by Ray Wilson titled Electroluminescence.
