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.
I produced this sound by programming a scale in a MIDI clip and then sending it to a virtual instrument designed to allow for freely manipulating granular synthesis through several seven point envelopes. I made several takes while I adjusted the envelops and other parameters.
One warning, this take has some piercingly high frequencies in a few places. The sound reminds me of some sort of scrambled futuristic alarm system. This led me to adding a warehouse reverb to the mix to put in into sci-fi thriller territory.
With very little time for today’s sound I resorted to randomizing the parameters in Pluggo’s xmod synth, then resampling the results as I dragged the mouse up and down on the virtual keyboard in Ableton Live’s sequencer. I often use this technique with a variety of VSTs as a starting point to get a new sound, so I thought I’d lay it down, so you can hear a little behind-the-scenes audio.
The conversation happening under Acceptable Use of Factory Presets and Samples? is starting to reflect the subject matter that is examined in the film Good Copy Bad Copy, so I thought it would be a good idea to reference it here in case any ACB readers haven’t seen it yet. I have been showing this one hour long documentary to friends and students since its release in 2007 and highly recommend it.
Good Copy Bad Copy is a fascinating look at the current state of copyright law and how it clashes with popular culture. The film has extended interviews with artists like Danger Mouse and Girl Talk, industry big wigs like Dan Glickman CEO of the MPAA, and IP and music copyright expert Dr. Lawrence Ferrara director of the music department at NYU. It covers the Brazilian phenomenon Techno Brega, a form of electronic music that merges western pop songs with latin styles, and takes a look at the rapidly expanding Nigerian film industry. The film can be viewed here at ACB, at their website, or legally downloaded from a torrent (www.goodcopybadcopy.net).
I am not, nor will I ever claim to be a guitarist, so please forgive the playing in this example. I do like the sound I have achieved here though. To get it I ran a cheap Fender Squire through VST distortion, thickly modulated chorus, followed by delay, and reverb. It’s very 80s, although I was not necessarily going for that. I does seem to go well in the piece in which it was recorded.
An issue that I often contemplate is, when is it acceptable to use factory presets and samples? I tend not to use them most of the time in favor of inventing new sounds and sampling from my own recordings and instruments. However, sometimes I make exceptions, such as using presets for classic keyboard sounds like pianos and organs, or individual drum samples for programming beats. Personally I have an aversion to using them, but I don’t doubt that lots of excellent music is produced using unchanged samples and factory presets. So the question remains, when is it a good idea and when is it a bad idea to rely on what has been painstakingly produced for us by industry professionals?
When I use presets I usually make some adjustments to in order to get closer to what I’m after sonically. In the piece Rihaku that I wrote with Nils Westdal for our album Truth is Stranger I used the factory sampled piano on the Yamaha A3000. I would have preferred to use an acoustic piano, but opted to give the sampler a go for budgetary reasons. In order to get a bit more sustain out of the sound I made some subtle but effective changes to the patch including manipulating the envelope, adjusting the velocity sensitivity, and slightly compressing the output.
