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.

Roland D50 Microtrack No. 4

Posted on January 9, 2011 by John CS Keston

The D-50 factory preset, A Fifth of Space, used in this microtrack sounds remarkably analog, a result of the unique linear arithmetic synthesis model that Roland debuted in this instrument.

Roland D50 Microtrack No. 3

Posted on January 8, 2011 by John CS Keston

This is the third in my series of Roland D-50 microtracks. Once again I used an evolving factory preset. This one is called Soundtrack and Hold. What I like particularly about this sound are the harmonic textures and the spacial qualities presented. There’s some serious ping pong going on if you listen on headphones.

Roland D50 Microtrack No. 2

Here another microtrack recorded with the Roland D-50 that uses another evolving factory preset called Sweep Loop on C.

Roland D50 Microtrack No. 1

Posted on January 6, 2011 by John CS Keston

As part of my One Synthesizer Sound Every Day project I am producing a series of microtracks inspired by the textures of factory presets or custom patches, found or discovered within a variety of electronic instruments. Today I’m presenting the first of these microtracks that I produced using my Roland D-50. I have had this synth since it was new. Yes, the one with the custom, spray painted, yellow stripes on it. Back then I had to have my father co-sign a loan for me to afford it. Although it was impossible to sample with it, the D-50 had a huge variety of sounds possible at the time using the built in 8-bit PCM sample library combined with Linear Arithmatic Synthesis or LAS.

I lost interest in the D-50 to analog, sampling, and modeling instruments for almost a decade, rarely bringing it out to use as a controller, or for an FX patch here and there. After seeing Roy Ayers keyboard player using one recently, I’m rediscovering the instrument as well as enjoying the nostalgia of hearing it again. One thing I don’t miss about it is how time consuming it is to program your own patches. Without the PG-1000 (BTW: I’m looking for one of these) it is a very tedious process, although it does have a joystick to modify selected values.

Fortunately the wealth of presets available for the D-50 still makes it a desirable instrument. To create this track I used the “Clock Factory” preset to produce a percussive loop. I can’t claim this composition as my own, since I’m simply playing a key and using aftertouch to alter the pitch, but it’s fun to appreciate the evolving patches that the Roland engineers managed to come up with.

One Synthesizer Sound Every Day Debut

Posted on January 5, 2011 by John CS Keston

It’s been more than fifteen months since I finished posting a self produced sound everyday for three hundred and sixty five consecutive days. This all happened in the One Sound Every Day category. As a result I produced my solo debut under my Ostraka moniker titled, Precambrian Resonance.

In the spirit of One Sound Every Day, I am starting a new project called One Synthesizer Sound Every Day. My plan is to use hardware synthesizers from my collection (and eventually soft-synths) to produce a sound, musical phrase, or microtrack to share here on ACB every day for a year. As well as my own sounds, I’ll be accepting select sounds from other artists and ACB readers to share on the site in the daily article.

My long term goal is produce a synthesizer album where I focus on inventing new sounds and allowing these textures to inspire the compositions. I’ve already got a good start on this by writing nine or so tracks in the few days since I conceived of the project (some of these tracks can be heard in the mix I shared here). I’m looking forward to sharing more of these sonic textures here as I discover them.

Let me start with a sub bass patch I made for my newly acquired Casio CZ-1000. I used to own a Casio CZ-101, which is virtually the same synth except that the CZ-1000 has a full sized keyboard compared to the mini-keys on the CZ-101. Years ago I misplaced my affectionately renamed Sleazy-101, probably in a move. Pining for the sound of this under-rated little instrument, I picked up a mint condition CZ-1000 on eBay recently for a steal. Here’s a bass line using my new patch.
