Presentation at the Ableton Live Users Group

abletonI will be presenting and performing at the Minneapolis Ableton Live Users Group on December 8, 2009 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.

Forgotten Complex

This piece, titled Forgotten Complex, was originally exhibited on and came about as a side effect of my contributions to the One Sound Every Day project. Rather than a percussion driven piece, Forgotten Complex relies on ambient Rhodes and other processed sound effects to create the lonely atmosphere of an abandoned warehouse. The piece is included on my solo album, Precambrian Resonance by Ostraka (Unearthed Music, 2009).

Chromatic Currents II

This second part to “Chromatic Currents” was produced with the GMS by using a string of lights placed into a large glass vase. I moved the camera around the vase to direct the flow of musical phrases with one hand while I adjusted transposition and note duration settings in the sequencer with my right.

You might notice that the video stimulus does not resemble lights in a vase. This is because I applied a negative filter to the video after capturing the performance. I used a pentatonic scale interspersed with rare dissonant notes and probability distributions in the note durations to give it an eerie awkwardness.

Traversing Samples with Granular Synthesis

This sound was generated using an instrument that I developed using MaxMSP tentatively titled the Wave Table Glitch Machine. The instrument uses TouchOSC as a controller running on an iPod Touch. I interfaced the accelerometer on the iPod to a filter so that when turned on with a toggle, tilting it on the y axis causes a lowpass filter to effect the sound. By setting a threshold on the z axis, giving the iPod Touch a brisk shake will cause the patch to loop a randomly selected grain of random length from a randomly selected buffer played back at a randomly selected rate. The variety of sounds possible with five short samples is expansive. Here’s a selection of sound produced with just one sample selected.

Chromatic Currents I

Chromatic Currents Part I is a generative music piece driven by particles floating in a liquid. No intervention in particle behavior occurred while the piece was being performed using the GMS. The scale was strongly C minor pentatonic, weighted with a Dorian mode by adding less-likely probabilities for D and A. However, every note that was not part of the scale still had a small possibility of occurring. This led to occasional blue or dissonant pitches in the sequence. The possibility of occurrences for any note within a twelve tone chromatic scale led me to the title.
