Reactive Graphics, The

Reactive Graphics, The from Jon Bobrow on Vimeo.
Gil Kuno's "Six String Sonics, The" gets joined by a set of reactive graphics designed with and programmed by Jon Bobrow. The graphics are responding to each of the six strings' amplitudes as well as parametric controls of the VJ. Over an hour long performance, the visuals migrate from very direct to more abstract representations the musics form.

During a sequence called "percussive shapes", the visuals are both responding to the guitarists as well as creating percussive sounds as the objects bump into the borders of the stage.

A custom application was written in C++ using OpenFrameworks to interpret OSC messages from Ableton Live, Midi controls from a Korg Nano controller, as well as allow for realtime custom charts of values, averages, and parameters for the visualizations. The application also synchronizes with an Ableton Live timeline to progress scene by scene with the specific visual forms.
