Ableton Live Users Group

Posted on November 30, 2009 by John C.S. Keston

I will be presenting and performing at the Minneapolis Ableton Live Users Group on December 8, 2009, 7:00pm at the Nomad in Minneapolis, Minnesota. In my presentation I’ll be showing what I do with custom built applications and Ableton Live, including the GMS and my new Wavetable Glitch Machine. Currently I interface my custom built applications with Live, using MIDI via the IAC drivers in Mac OS X, and Soundflower for audio. Soon I’ll be converting my audio based Max patches over to Max for Live, so I can use them in Live directly.

Also appearing is Ali Momeni who’ll be showing some of his Max for Live patches, and JP Hungelmann who also organizes the event. Last time the group met it was held at IPR and there was an excellent turn out. The speakers were terrific and they gave away Ableton demo discs and t-shirts at the end of the event. If you use Live, have any interest in it, or electronic music in general, I highly recommend attending.

Ostraka with Dial System Performance

ostraka_at_kck My new experimental music project with Graham O’Brien, Ostraka with Dial System, will be performing on December 20, 2009. Originally I had written that we were performing on December 8, 2009 as well, but that performance has been canceled due to a prior engagement.

Ostraka with Dial System is myself on laptop using my custom developed application, the Gestural Music Sequencer (GMS), and Graham O’Brien on drums. 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.

GMS Beta Release, September 28, 2009

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.

500 Million Years From Now

Posted on August 11, 2009 by John C.S. Keston

dots It was recently estimated by Edward Guinan at the XXVIIth General Assembly of the International Astronomical Union that our lonely planet is nearing the end of its habitability for life as we know. Albeit, on a cosmological timescale. Between .5 and 1 billion years from now, increases in the Sun’s temperature will cause the Earth’s oceans and atmosphere to evaporate.

Shortly after reading this article I opened up my Ableton Live set from Sunday night to listen to some of the loops I had captured with the GMS during the show. After opening the document I pressed play and heard a stark landscape of reverberation. I saw visions of a lifeless, peace 500 million years from now.

What had happened was that when saving the document I had left all my master effects in their last position. I decided to capture these sounds and vary them over time. The effect chain on the master track included a low pass filter, bit reduction, delay, and reverb with nine parameters mapped to knobs on a controller. Here’s what I ended up with on the second take.

Getting Reacquainted with the GMS

Posted on August 6, 2009 by John C.S. Keston

triquetra_rehearse I have had a number of problems migrating my Processing.org application known as the GMS from my old MacBook Pro running OS X 10.4.11 to my new one running 10.5.7. The first issue was alack of support for the IAC drivers in Java, next were some funky conflicts with the Java class I was using to load and save presets. With the help of Grant Muller I have solved these problems.

While I was at it I took on a couple of other issues as well in preparation for my performance on Sunday. All that’s left is for me to become reacquainted with the application in tandem with Ableton Suite 8.

This is actually the hard part because I have use the application effectively as an instrument and real-time visualizer. One problem is running out of hands and fingers while producing the visuals and capturing the MIDI clips. Another danger is the music becoming repetitive while making adjustments. Here’s a quick recording I made while practicing.
