ISSTA 2018 and Ableton 10 NRPN Morphing

Soon I’ll be on my way to Ireland for my second appearance at the Irish Sound, Science and Technology Association (ISSTA) annual conference. This year ISSTA will be held at Ulster University’s Magee campus in Derry, Northern Ireland, November 9th and 10th, 2018. Tickets are still available.

This time around my work is entirely rooted in FM synthesis. Particularly around my explorations of the amazing PreenFM2. I have designed a Max for Live patch that allows me to degrade, morph, and/or scramble sets of parameters on the synth. This is similar to a device I designed for the Yamaha TX81Z. This process creates an algorithmic approach to the sound design. Continue reading

New Spectral Tablature Collaborations Exhibited in Tokyo

I am pleased to be participating in an exhibition of work by Jasio Stefanski at Print Gallery in Tokyo, Japan. Jasio is showing a variety of his work including two pieces that we collaborated on together fron the series Spectral Tablature. The first piece is Synthetic Skyline previously exhibited for the Audible Edge sound art exhibition at the Katherine Nash Gallery in Minneapolis. The second piece is a new work in the series titled Synthetic Transitions.

Synthetic Transitions

To create the work I started by composing a simple sequence of notes that speed up and then slow down. Jasio requested that we included diagonal lines in the piece so I used linear portamento on the Moog Sub 37 to create the “transitions” he was interested in seeing. The video shows the plotter rendering Jasio’s Reprise of the work shown/heard in the image/audio below.

Synthetic Transitions Reprise

Jasio’s Reprise is based on form and color values as opposed to acoustic accuracy. The visuals were composed to place emphasis on the “transitions” or portamento. The output visually reinterprets the angles informed by the gliding notes without connecting them in the composition. When sonified the plotted design singles out the portamento, isolating it from the context of the sustained frequencies.

Duets with the Singing Ringing Tree

In May, 2014 I performed Duets with the Singing Ringing Tree (SRT) in Northern England. The SRT is a permanent, wind-activated sculpture by London-based architects, Tonkin Liu. For five days I documented dozens of analogue synthesizer improvisations with the SRT using a binaural-head microphone. After returning to Minneapolis I produced and published a series of six of these pieces as video documentation on YouTube. These works, in the words of Peter Kirn from CreateDigitalMusic.com, evoke an “eerie resonance.” The synthesizer accompaniment alternates between contrasting and mimicking the haunting tones of the cold, metal structure. Read on for a series of photos from the project.

NOTE: These are binaural recordings combined with synthesizer accompaniment. Although it sounds great through speakers, circumaural headphones must be used to experience the binaural effect.

Music with Context: Audiovisual Scores for Improvising Musicians

Thesis Venn Diagram 2.0 - New Page

A good stretch of my time working on my MFA in New Media at the Minneapolis College of Art and Design (MCAD) was spent working on my master’s thesis. Here’s the abstract:

This paper explores the idea of mutable, audiovisual scores for improvised musical performances through the description of personal perspectives, practical examples, proposed projects, and research. The author postulates that an audiovisual score can be a useful tool to connect improvising musicians to each other and their audience through the insertion of a mediating audiovisual layer within the work. These systems are used as a primary influential agent for an ensemble of improvisers, providing them with a context for a musical conversation. In contrast to traditional notation and graphic scores, audiovisual scores embrace the chaotic ambiguities of environmental influences giving the music the context of unpredictable everyday events. Presenting an unpredictable audiovisual score parallels the indeterminate improvisation of the ensemble. It activates the last vestige of what remains immutable within traditional forms of notation driven performance inserting it into a mutable layer within the work.

In my thesis you will find detailed, conceptual explanations for many of the projects that I have shared here over the last few years. There are also references to work by many other artists who have provided inspiration to me. If you’re interested please click the link below to view or download the document.

Machine Machine Touchscreen Instrument

Machine Machine (2013) is a 32″ touchscreen installation that functions as an electronic instrument. Granular synthesis is used to loop “grains” of sound and video at variable lengths and frequencies. These parameters are based on the y-axis of the touch point on the monitor. The x-axis determines the position of the grain within the timeline. The piece was exhibited last month at the Northrup King Building in Minneapolis during Art-a-Whirl and for Visual Storage; the MCAD MFA thesis exhibition.
