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.

Novation Circuit Randomized Patches

Posted on December 21, 2016 by John CS Keston

In my mind, sound design is at its best when it is a process of discovery. At its worst it can be an unfortunate exercise in mimicry. I am fascinated by the process of discovering sound through happy accidents. One of the techniques I have exploited frequently in this regard is synthesizer patch randomization. For example, the Yamaha TX81Z sounds great when randomized, or better yet, “degraded” with shuffled parameter values interpolated based on a time unit or clock division. The PreenFM2 has patch randomization built directly into the instrument!

So, it wasn’t long after picking up a Novation Circuit that I had the urge to use a similar shortcut to mine fantastic and otherworldly sounds from the unit. Full MIDI specification for the Circuit is available so that development of a standalone randomizer is possible, but Isotonik Studios published a free Max for Live editor in partnership with Novation. Max for Live patches are inherently editable so I decided to start there.

It took me a couple of hours to get into the guts of the editor and setup a drop down menu for randomization. The drop down has choices to either “randomize all” (not quite all parameters), or randomize one of seven sets of grouped parameters like the oscillator section, mod matrix, or LFOs. At his stage I haven’t included the EQ section, voice controls, or macro controls. I probably won’t add the EQ, but the macro controls might offer some interesting possibilities. The image above shows a simple subpatch I made that takes a bang and outputs the random values for the oscillator section. Unfortunately, I can not legally share my mods based on Isotonik’s and Novation’s EULAs. However, you’ll need little more than a basic understanding of Max to do this yourself. Checkout the video and let me know what you think in the comments.

Wednesday Performance at the Triple Rock

Posted on December 13, 2016 by John CS Keston

This Wednesday I will be playing an improvised solo set of synth music at the Triple Rock Social Club in Minneapolis. I produced this teaser by crossfading a few clips from my rehearsal for the show. The bill, hosted by Hardcore Crayons, also includes Clustercuss and collaborative performances from everyone. Enjoy!

Squarp’s Pyramid Sequencer Firmware v1.0

Posted on November 28, 2016 by John CS Keston

Squarp’s Pyramid sequencer just got a new firmware update with the prestigious versioning of 1.0. I’ve had mine now for almost a year and have seen a slew of software updates during that time. The new features in 1.0 include a new LFO MIDI effect. These LFOs can be chained together creating all sorts of possibilities.

Solo Electroacoustic Piano Teaser

Posted on November 23, 2016 by John CS Keston

This teaser for my show tonight at Jazz Central Studios includes a handful of snippets from my rehearsals of the electroacoustic piano pieces I’ll be performing. It’s all acoustic piano with processing that includes delays, live looping, freezing reverb decay, and reverse. The last snippet also includes the use of a felt mute between the hammers and the strings. The tone is much darker, softer, and subdued.

Solo Electroacoustic Piano at Jazz Central Studios

Posted on November 9, 2016 by John CS Keston

I feel excited and privileged to be playing a concert of original piano compositions on November 23, 2016 at Jazz Central Studios in Minneapolis. The compositions include acoustic piano pieces (unaltered by processing or electronics) and a number of electroacoustic piano pieces that will involve manipulating the signal from the piano in real-time. For example I’ll be using an analog delay to create pulsing washes of sound from the piano. There will also be examples of sampling and looping the piano and then manipulating the loops through more processing.

Although ACB readers will be more familiar with my electronic work, acoustic piano is the instrument that has stayed with me since childhood. I even had a weekly jazz piano gig that lasted eleven years! This upcoming solo piano performance will be my first in over a decade and it will be very different for me because I’ll be playing my own compositions instead of a the jazz standards I used to play.

Jazz Central Studios has a really great sounding grand piano in house that I’ll be playing during the show. I have performed at the venue a number of times recently thanks to friend, bassist, and collaborator, Casey O’Brien who is one of the current artistic directors for the non-profit organization. Here’s some more information about JCS:

Jazz Central Studios (JCS) is a tax exempt nonprofit organization committed to strengthening the Twin Cities jazz community by offering a live performance/educational environment that nurtures artistic growth. Our space consists of 1800 square feet which seats up to 50 people. It is complete with grand piano, house drum set PA, and lights.

In 2010, local jazz musicians Mac Santiago and Tanner Taylor established Jazz Central Studios as a rehearsal and recording space for Twin Cities jazz musicians. We encourage jazz patrons and musicians of all levels to become a part of Jazz Central Studios. Whether you want to develop your skills and career as a performing musician or you want to meet other jazz enthusiasts and support the local scene, there is a place for you here.

The music on November 23, 2016 will start at 8:30pm. The suggested donation is $10 for general admission and $5 for students. I hope you’ll join me! Here’s an excerpt from a recording of me (piano, electronics), Cody McKinney (bass, voice, electronics), and Graham O’Brien (drums, electronics) made at JCS by Diego Ramallo. In the recording I’m using a sampler to live-loop piano layers and then run things through delays and other processing.
