45 Delusions for Common Time at the Walker Art Center

Posted on June 26, 2017 by John CS Keston

45 Delusions was commissioned by the Walker Art Center for an event with former Merce Cunningham Dance Company (MCDC) dancers as part of the Common Time exhibit and performance series. The piece was performed and recorded with the dancers on March 30, 2017 in the Perlman Gallery at the Walker Art Center, Minneapolis. My setup included Rhodes, Moog Sub 37, PreenFM2, Korg KP3+, and a Moog Minifooger Delay. Graham O’Brien performed on percussion and electronics triggered from his drums.

John Keston's Setup for the Common Time Event

My Setup for the Common Time Event

The score is two pages. The first page (pictured at top) is the timeline for both performers. The timeline is vertical and made up of cells that last between one and five minutes each. Frequently the cells correspond with each player, but they are arranged so that at times they overflow. Rests are also included as cells. Each cell includes brief instructions and/or graphics that give suggestions to the musicians. Some of the instructions are expanded on the second page of the score.

Graham O’Brien’s Setup for Common Time

The second page also includes a list of forty five delusions. These include terms such as alternative facts, capitalism, corporate culture, equality, freedom, fossil fuels, greed, justice, and so on. There are also a few technical delusions such as erotomania (belief that a celebrity is in love with you) and lycanthropy (belief that one can turn into an animal). The second page explains the delusions and what to do with them:

DELUSIONS
Anything that might be considered or is delusional. These are not necessarily medical or technical examples of delusions and may involve individuals, societies, or organizations. Prior to performing the piece, each musician chooses one “delusion” applied to each cell within the score.

Take a look at the PDF at the end of this article to see the complete list of delusions as well as expanded instructions for some of the cells. Obviously this is an improvised piece of music, but this approach steers the improvisation in directions that would be unlikely to occur freely. Particularly the timing. As one performs or listens to the piece it is possible to discern distinct variations as the musicians transition from one cell to the next. If you are inclined to listen to the piece in full, try following along with the score and placing a SoundCloud comment where you hear the cells change. The timing on the recording doesn’t exactly match the score, but it’s pretty close.

The reasons I took this approach are multi-faceted: (1) It keeps the piece moving. Often free improv tends to stagnate as ideas are repeated and refined. With this approach the challenge is to express ideas with concision and then move on to the next (this is possible, albeit rare, in free improv – we call it channel surfing). (2) It is possible to strictly define the length. We used a timer that counted up to 30 minutes. One quick glance at the timer illustrates the need to move on to “High Speed Arps” for example. (3) Mood, dynamics, and theatrics can be injected to create a narrative with scope and meaning. It is a way to ask questions, discover sounds, explore, and experiment. (4) It enhances my musical engagement. I am influenced by my collaborators and surroundings, but I’m also interpreting the language of the score, and hopefully to the benefit of the musical output.

Un:heard Resonance at Northern Spark, June 10, 2017

Posted on June 8, 2017 by John CS Keston

This Saturday, June10, 2017 I am participating for the sixth time in Northern Spark. The project I’m directing is called Un:heard Resonance. Also involved are artists Mike Hodnick AKA Kindohm (music), Chris LeBlanc (visuals), Lucas Melchior AKA MKR (music), and Aaron Marx (design). I’m am also fortunate to have the help of several student / former student volunteers inlcuding: Mike Brooks, Mike Miller, Meg Gauthier, and Justin Maki. The piece will be performed at the Weisman Art Museum from 8:59pm to 5:26am. Yes, that is eight hours and twenty-seven minutes!

The piece is comprised of a series of electronic sonatas composed in real time with micro-sonic signals crowdsourced from the audience. A variety of microphones and sensors will be used to capture rarely heard vibrations emitted by geological, biological, and technological processes. Three movements chronicle the stages of the planet’s evolution: Geology, Biology, and Technology. The project will bring awareness to sonic activity rarely experienced within the environments we live in and exploit. The combination of micro-sonics and accompaniment will non-verbally stress hidden geological processes, the fragility and jeopardy of the ecosystem as it faces climate change, and the rapid, global expansion of technology.

It will also imply that technology may eventually replace the geological and biological states of the world. A precedent for this idea resides in the concept of “Computronium” theorized by Norman Margolus and Tommaso Toffoli at MIT, a hypothetical state of matter that would yield the most efficient and powerful atomic arrangement for computer processing. The Geology and Biology sonatas represent the first two sequential stages in the evolution of the planet, while Technology suggests the dystopian possibility of the world becoming a giant computer that no longer supports life as we know it.

Northern Spark attracts more than 100,000 visitors to experience hundreds of interactive art, music, and performance projects throughout the Nuit Blanche. This year the overall theme is Climate Chaos | People Rising. All the projects will be shown along the “Green Line”, a light rail line that stretches from downtown Minneapolis to downtown St. Paul, Minnesota.

Revisiting Dogmatic Music with the Novation Circuit, PreenFM2, and Moog Sub 37

Posted on May 16, 2017 by John CS Keston

I composed this track and performed it live while limiting myself to using three electronic instruments: Novation Circuit, PreenFM2, and a Moog Sub 37. Afterward I added a recording of a Tibetan tingsha bell that I captured using a matched pair of Rode NT5 condensers. The instruments were sequenced using the Squarp Pyramid, which might technically be considered a fourth instrument, but it is not a sound source.

I continually revisit dogmatic approaches to making electronic music and this approach in particular may yield some interesting results. The last collection I made like this was back in 2013 and can be found in the post Builders of the Fauxpocalypse: a Dogmatic Approach to Music Making.

Programmable MIDI Foot Controller for the Korg KP3+

Posted on May 12, 2017 by John CS Keston

The Korg KAOSS PAD KP3+ is a powerful beast. It’s great for realtime processing and sampling, but it’s not the best choice as a loop pedal. For one, the loop record length choices only include 1, 2, 4, 8, and 16 beats. You can adjust that after recording, but not on the way in. One shot samples can be any length, but they need to be triggered manually or via a sequencer. Furthermore, it’s not a pedal. If you want to trigger or record samples with your feet you’ll need a MIDI foot controller to do that. And not just any controller. It will need to be programmable so that you can send specific note values to the KP3+ that trigger each of the sample buttons.

This is the issue I decided to resolve for my continuously evolving live setup. More often than not I use a Rhodes electric piano with the KP3+ alongside a modest family of other gear. Playing two-handed while capturing Rhodes loops without audible gaps is impossible if you have to use a “spare” hand to do it. There are a number of programmable MIDI foot controllers on the market. Unfortunately, most of them are not fully programmable and are designed for changing patches versus triggering MIDI notes. An exception to this is the Behringer FCB1010, however, it’s quite large with twelve switches and two expression pedals. I only need four switches and can’t afford the space the FCB1010 would take up.

People are making all sorts of custom MIDI controllers and there’s tons of microcontrollers that can be used for this purpose. I won’t get into all the options, but a few examples include Arduino (perhaps with a SparkFun MIDI shield), Teensy, Livid Brain V2 or Brain Jr, and Highly Liquid’s MIDI CPU. It just so happened that I had a Highly Liquid MIDI CPU on hand that I was sent to me as a sample years ago. I had used it for a few experiments, but nothing on a permanent scale.

Following instructions on the Highly Liquid website I was easily able to reprogram the MIDI CPU via sysex and start testing it with the KP3+. In minutes I had a prototype working that was triggering the sample buttons properly. With that piece confirmed I ordered four momentary foot switches and a sturdy aluminum enclosure. I measured and drilled all the holes for the four switches, DC power, MIDI in, and MIDI out. I soldered it all together and started using it immediately. I’m very pleased with the results and hope to use the foot switch for years to come. To an extent it is future proof because at anytime I can reprogram it via sysex through the MIDI input. A second reason the MIDI in is useful is because I can still send the connect device MIDI from another source (MIDI clock for example). This works because the MIDI CPU can be configured to mirror the MIDI in to the MIDI out while merging messages that originate from the circuit board. Handy!

This was an inexpensive, easy, and elegant solution to a frustrating problem. Custom MIDI controllers are getting easier and cheaper to build all the time. I’d love to hear about your DIY MIDI controller projects in the comments below. Thanks for reading!
