GMS Beta Release, September 28, 2009

Posted on September 23, 2009 by John CS Keston

gms_grab I have decided on September 28, 2009 as the release date of the GMS, coinciding with my performance with Graham O’Brien, and my birthday. We can call it a combination Ostraka with Dial System and DJ Zenrock show, GMS beta software release, and birthday party. Currently I am releasing a binary version of the software for Mac OS X only. A windows version is in the works, with no prediction of when it’ll arrive.

The GMS is a Gestural Music Sequencer that I developed in Processing (processing.org). The application samples video and displays it either normally or inverted so it looks as though you’re looking into a mirror. Each frame is analyzed for brightness, then the X and Y data of the brightest pixel is converted into a MIDI note. These notes produce a non-repeating sequence based on movement within the range of the capture device.

For more details, including audio examples and video produced using the GMS, checkout the
GMS category. There’s also a Gestural Music Sequencer Documentary Short produced by Josh Clos, that does a good job of illustrating what the software does.

Ostraka with Dial System and Keston and Westdal Performances

Posted on September 16, 2009 by John CS Keston

I have a few performances coming up. One at the end of the month and two at the begining of October. Here’s the official word from Unearthed Music on the upcoming events:

Unearthed Music has a few upcoming events we thought you’d like to know about. On Monday, September 28, John Keston is celebrating his birthday by performing with Graham O’Brien on drums as, Ostraka with Dial System at the Kitty Cat Klub. The duet combines the stochastic, angular melodies produced by Keston’s custom music software with live drumming. Gestural video input is simultaneously projected onto a screen and processed into musical phrases. The results are live looped and molded into spontaneous compositions. Expert, veteran turntablist, DJ Zenrock, completes the bill.

Keston and Wedstdal with Graham O’Brien on drums are performing back-to-back events at Sauce with House Luna and Honey Stick (Thursday, October 1, 2009, $5.00) and the Dakota late night (Friday, October 2, 2009, $5.00). Sauce is located in Uptown on Lake and Lyndale and the Dakota is on Nicolet Mall in Downtown Minneapolis.

Ostraka with Dial System Live

Posted on August 4, 2009 by John CS Keston

5tgr5tdry My new duet, “Ostraka with Dial System” (John Keston and Graham O’Brien) is performing at the Kitty Cat Klub in Minneapolis on Sunday, August 9, 2009. This group combines the stochastic, angular melodies produced by the GMS with live drumming. Gestural video input is simultaneously projected onto a screen and processed into musical data. The results are captured in real-time and molded into spontaneous compositions. Special guests include DJ Zenrock and Terr the Om.

To get an idea of what you might hear, have a listen to these examples from a rehearsal recording that was made in May, 2009.

GMS Ensemble Live Performance

Posted on June 24, 2009 by John CS Keston

Nils Westdal shot this video of myself and Graham O’Brien on drums performing with the GMS during one of the Flashbelt after parties on June 8, 2009. The party was held in the back alley of One on One bike studio, considered the bike Mecca of the Midwest.

Recorded using the internal mic on the video camera, the mix is chatty and pretty drum heavy for the first half, but you can hear the GMS sequencing a little better toward the end.

The setup consists of a MacBook Pro running the GMS synced to Ableton Live 7, an M-Audio Firewire 410 interface, a Mackie 1202 mixer, my Korg MS2000 for external control of the GMS, a Casio projector, and a variety of bike lights and spinning LED tops as “light controllers”.

MAW Outing GMS Excerpt

Posted on May 15, 2009 by John CS Keston

Here’s a segment of audio from Wednesday’s MAW outing at Art Institutes Minnesota in downtown Minneapolis. I’m pretty happy with the arpeggiated, melodic loops I’m able to achieve with the right settings and a good light controller using this application. For video documentation of what was happening at the event, please visit minneapolisartonwheels.org.

This video shows me using various light controllers, including a string of patio lights, bike lights, and LED spinning tops to construct compositions using the GMS.
