Music for People on Shelves

Posted on December 10, 2009 by John C.S. Keston

people_on_shelves I’ve just rendered my full eighty-six minute Ostraka set from last night’s event at the West Bank Social Center. So, while waiting for the delightful documentation that Andrea Streudel is sure to produce, here’s a short segment of audio from the set.

I used Ableton Live to produce in real-time and my wavetable glitch machine Max patch to make most of the noises, which I routed into Live using Soundflower.

The projection work of the evening was top notch. An entire wall of the building across from the WBSC was covered with animated silhouettes of attendees on simulated three dimensional “shelves”.

Here’s the excerpt. I’m also including a link to the entire eighty-six minute set that I uploaded to soundcloud.com for all the brave people who’d like to hear the full set.

Radiolab Numbers

Posted on December 2, 2009 by John C.S. Keston

numbers WNYC‘s Radio Lab with Jad Abumrad and Robert Krulwich is one of my favorite radio programs and podcasts of all time. Their latest program explores the world of numbers. According to interviewees on the program all babies think logarithmically until the abstract concept of integers has been systematically drilled into their heads.

It’s a fascinating story, and as usual, permeated with beautifully done sound design. For more on Radiolab checkout “Sound is Kind of Touch at a Distance”, or visit their site for more podcasts of the program.

Snyderphonics Manta

Posted on November 24, 2009 by John C.S. Keston

Recently I read an article in Future Music on the Snyderphonics Manta OSC controller. I’m getting more and more into OSC (Open Sound Control), so this is a really fascinating device that I can see replacing and expanding upon what I’m building for the iPod Touch. The Manta has forty-eight touch sensors on a six by eight pad. Each sensor can handle note on/off and velocity information, which you can’t do on the iPod Touch. It also has two touch sliders and four touch buttons, all assignable via OSC, or MIDI with a free application that’s available on synderphonics.com. The device also accepts input in order to provide feedback via LEDs that back light the controls. I have been researching and experimenting with multitouch devices to do music and sound design for a while now, and the Manta seems to solve a lot of shortcomings of other devices. Congratulations to Jeff Snyder for designing a unique and intriguing instrument.

Multitouch Rotary Dial and X-Y Granular Exploration

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.

Five Output Atemporal Looper

Posted on November 4, 2009 by John C.S. Keston

Here’s a screen grab of a patch I’m working on to successively loop five phrases of sound repetitively. For example, looping another phrase after the fifth time will replace the first and so on. The goal of this patch is to allow me to feed in audio signals from my multi-touch glitch machine into the looper so I can build compositions for a five speaker sound art installation I’m doing at the end of this semester at the University of Minnesota.

For the example I routed outputs 1, 3 and 5 to the left channel and outputs 2 and 4 to the right channel. I also temporarily generated a randomly pitched sinusoid to run into the looper for testing. The large toggle in the upper left initiates the looping and pressing it again stops it. Currently there’s no mechanism to find zero crossings, so the result has lots of clicking in the output. To make good use of the clicks (I’ll be fixing this later) I routed the output into Ableton Live, and loaded on heaping portions of distortion and delay. If life gives you clicks, make click-on-aid.
