The Battle of Everyouth Rehearsal Segment Part 1

Posted on May 27, 2011 by John Keston

On Saturday, June 4, 2011 from 9pm until midnight I will be performing with DKO (Davis, Keston, O’Brien) and DJ Luke Anderson at the Minneapolis Institute of Arts (MIA) for the Northern Spark Festival. Our experimental music will be live accompaniment for an amazing piece called the Battle of Everyouth (Jenny Schmid and Ali Momeni). Here’s a more detailed description of the piece.

The Battle of Everyouth is a projection-based performance which blends live cinema, participatory theater, music and live animation. A miniature set, the Circarama serves as a tiny stage for projections and stop motion animations, while wireless devices offer ways to engage with live theater and contribute to the resulting projection panorama on the facade of the Minneapolis Institute of Arts.

DJ Luke Anderson joins the amazing trio, DKO, which features Jon Davis (Bass, Bass Clarinet), Graham O’Brien (percussion) and John Keston (Rhodes, Pro-One, electronics) for live experimental music on the steps of the MIA.

Students from Washburn High School are audience guides. This group has been studying youth and violence in their Art, Geography and Literature classes during the Spring, 2011 term. Their studies have included a mock United Nations focusing on child soldiers, the reading of graphic novels Persepolis by Marjane Satrapi and Maus by Art Spiegelman as well as discussions about artists that address controversies about borders, faith and security.

Artists Jenny Schmid and Ali Momeni are stationed at a “mixing station” which combines live video feeds from these numerous dispersed performance contexts. Jenny layers drawings and words over the input imagery, while Ali animates and manipulates the many visual elements of this project.

In preparation we have begun rehearsals to formulate musical strategies and create a vocabulary of ideas. Here’s a short segment from one of these rehearsals featuring Luke Anderson on electronics, Graham O’Brien on drums, and myself on GrainMachine with some Rhodes toward the end.

Water Dripping Sample in GrainMachine

Posted on May 23, 2011 by John Keston

This evening I have been working on the user interface for GrainMachine, a Max for Live instrument I developed for personal use in October of 2009. In the process of tonight’s testing I came up with this sound. I started with a sample of water dripping, loaded it into GrainMachine and then chose a very narrow grain at a fairly low frequency. Finally I swept slowly through the position of the sample creating the result heard below.

GrainMachine Release and Example Sample

Posted on May 7, 2011 by John Keston

Recently I have been working hard on getting my Max for Live instrument, GrainMachine, ready for release. It’s just about ready to go. I can’t name a date just yet, but I can tell you that it will be available as a free download. Here’s an example sound that I created with the instrument to go along with an example Live set I’ll be including with the release.

Tonight I am demoing my Grain Machine Max for Live instrument at Handmade Music Minneapolis #6 (click for details). Lots of other people are showing off their goodies including Kris Peck of Xenharmonic Instruments, Adam Loper showing his DIY MIDI controller, MCTC students sound synthesis projects, and more. Here’s a few seconds of typical Grain Machine output to wet your appetite.

DGK Improv with Drums, Soprano Sax, Pro-One, Monotron, Posc, and Grain Machine

Posted on April 8, 2011 by John Keston

This 1:52 minute segment of improvisation from the DGK performance at Try This 2 on March 25, 2011 contains drums by Tim Glenn, Soprano Sax by Jon Davis, and jumble sale of gear played by yours truly. These instrument include, in order of appearance, the Sequential Circuits Pro-One, followed by the Korg Monotron, my handmade Sonodrome Posc, and my Max for Live, granular synth, Grain Machine. Prior to this performance I had been limiting my palette of textures to the Rhodes and the Pro-One, but for this performance I thought I would try including the Monotron, Posc, and Grain Machine in order to draw from a few more atonal colors.

Video by Jon Davis of an Ostracon Performance

Posted on December 20, 2010 by John Keston

I just came across this five minute video shot by Ghostband artist Jon Davis on his mobile phone of my duet project Ostracon performing at the Kitty Cat Klub in Minneapolis on July 17, 2010. I’ve been enjoying a lot of these lofi videos that Jon puts up on YouTube, and it reminds me of a quote I read recently from David Byrne in the liner notes for My Life in the Bush of Ghosts: “…we came to realize that high fidelity was a vastly over-rated convention that noboby had bothered to question…”. I can’t agree more, except that today, thankfully, it is being questioned more than ever.

Words to Dead Lips Closing Night Excerpt

Posted on November 8, 2010 by John Keston

As I’ve mentioned in some previous articles, I have been working on a multi-media dance collaboration, Words to Dead Lips, with Annichia Arts since last December that has finally come to a close. We staged three performances at Intermedia Arts in Minneapolis this weekend to a mostly full house. My part in the collaborative effort was to produce the music, and I was given an open mandate to do so. As is my preference, I opted to perform the work to the dance and projected imagery, rather than submit pre-recorded material. Although I adhered to an agreed framework for the soundscape, the improvisational nature of this approach made every performance unique.

The main tool that I used to generate the sound was my Max for Live patch, Grain Machine that explores granular synthesis via a multi-touch controller. I loaded it with five samples including Snow Melting into Lake Superior, One Hundred Sounds in Eight Seconds, High and Low Frequency Drone, and a couple of others for the piece.

Another component to the sonic environment was the noise shield. This device, that I built into saucer sleds, was used by the dancers to synthesize sounds using body contacts and a light dependent resistor. Here’s a five minute excerpt of audio from the closing night’s performance.

Grain Machine Update and Layered Experiment

Posted on August 2, 2010 by John Keston

Here’s a new look at the Grain Machine M4L device. Since last time I have updated the device to allow drag and drop samples that are stored with the Live set, and added a visual for the filter that’s controlled by the accelerometer on the controller (iPad, iPhone, or iPod Touch).

The best thing about using this in Live is being able to live-loop and layer the output from Grain Machine into clips on different tracks, not to mention processing. Another advantage is saving the state of the device in the Live set so that one document has sample set X, while the next has sample set Y. Here’s a piece I created with the Grain Machine in Ableton Live using some samples I randomly selected from my sound library.

Grain Machine Max for Live Instrument

Posted on July 30, 2010 by John Keston

The Grain Machine v0.1

Something I have been meaning to do for a while was convert the MaxMSP instrument that I titled the Wavetable Glitch Machine (WTGM) into a Max for Live patch. The WTGM uses a TouchOSC interface running on an iPhone, iPod Touch, or iPad to explore samples using granular techniques as well as a virtual scrub dial with friction modeling. Visit the WTGM tag to read more and view a video of it in operation. I have renamed the instrument Grain Machine for the M4L version.

First I prepared the patch for transfer to M4L. This involved making sure that all of the interface objects were in the main patching window, reorganizing the sub-patchers, and cleaning up a variety of other things that I imagined might interfere with the process. Following that, all that was left was copying and pasting the patch into a Max Instrument, replacing some of the standard Max objects with M4L objects, and building a tidy little presentation mode.

Although I had to rework some of the logic and patch cords, the conversion went surprisingly fast. I expected to be working on this for weeks, but it only took me a matter of hours to get it into working order. There is still some fine tuning to be done, but all the necessary functionality is in place. Here’s an audio example I made with a simple breakbeat loaded into the Grain Machine.

Multitouch Rotary Dial and X-Y Granular Exploration

Posted on November 6, 2009 by John Keston

With help from Josh Clos I have shot a short video documenting what my latest MaxMSP project does.

It’s a sort of swiss army knife of wavetable glitch machine and sample scrubbing tools. Hopefully the video will shed some light on what this project is about. I’ve been trying to describe it in a few other posts without much success, but seeing it in action seems to make a bit more sense.

The next step invovles integrating this tool into the Five Output Atemporal Looper i describe in my last entry.
