Social Distance II with Corrector Records Live Stream

Posted on March 29, 2020 by John C.S. Keston

Saturday, March 28, 2020 I had the privilege of performing a solo, electronic, live-streaming set for Social Distance II with Corrector Records. I played first followed by live coder Mike Hodnick AKA Kindohm, and Carl Fisk AKA Mount Curve. The series aims to fill a void left by the lack of live concerts while raising funds to help support artists who are struggling financially.

Fortunately the bulk of my income is from teaching at a university (now entirely online), but many of my musical mates rely on performing almost daily to make ends meet. Due to lockdowns and gig cancellations for preventing the spread of COVID-19 they are making little to no income. Please help support artists in need at https://www.givemn.org/story/Epf3ag. If you are an artist in need of assistance apply for funds at https://springboardforthearts.org/additional-resources/personal-emergency-relief-fund/.

My set was improvised using the Sequential Prophet REV2 with realtime, generative sound design handled by an application I recently released titled REV2 Degrader™. I also played Rhodes electric piano and processed and looped things with the Korg KP3+, and Moog Minifooger Delay.

Video: Panic by Proxy Live at the Walker

Posted on November 15, 2018 by John C.S. Keston

On August 23, 2018 I debuted a new piece in remote collaboration with Syrian artist and filmmaker Khaled Alwarea. PANIC BY PROXY is an audiovisual translation of clips from Alwarea’s award winning film Panic Attack. The piece was commissioned by MN Artists for their MN Artists Presents series at the Walker Art Center, curated by Essma Imady.

The performance featured audiovisual objects projected and amplified while being granulated using Audiovisual Grain Machine (AVGM) — software I developed that performs audiovisual granular synthesis in realtime using a touch controller. Other instruments included Rhodes, Moog Sub 37, Novation Circuit, Korg KP3+, and an Electro-Harmonix Memory Man Delay. The dissonance, distortion, and uncanny synchronization in the sound and visuals illicit feelings of disturbance and confusion as an expression of the artist’s anxiety.

This video includes most of the performance and has only been edited for length. Thanks to Esmaa Imady for inviting me to participate in the event, Khaled Alwarea for his amazing film work, and Emily Gastineau at MN Artists for organizing the event.

45 Delusions for Common Time at the Walker Art Center

Posted on June 26, 2017 by John C.S. 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.

Programmable MIDI Foot Controller for the Korg KP3+

Posted on May 12, 2017 by John C.S. 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!
