Performed live on September 9th, 2021 at Culture Lab LIC in NYC as part of a showcase put together by Never Knows Better at the Ars Electronica Festival Garden.
This performance utilizes a fully DIY modular audiovisual synthesizer, a collection of custom controllable systems built in Touchdesigner, and a CRT TV which has been modified into an pseudo-oscilloscope receiving dedicated audio & video feeds to generate colored waveforms.
Three 60Hz tones are generated by the AV modular representing the three RGB color channels, panned left, center, and right respectively. These three underlying tones, which the piece is fully built around, have harmonics which shift depending on the shape of the individual color channels in the image, with peaks of amplitude being built for each color's pixels as the image is scanned through on each refresh of the video signal. Additional waveform generators and simple oscillators are injected into the color channels and 'played' in tune with the underlying tones by dialing in exact frequencies, which at multiples of 60Hz, will also form stable scanlines in the receiving color channel.
Touchdesigner serves as a complex collection of controllable systems for handling & manipulating audio, video input, as a standalone visual system, to introduce generative elements and contained-randomness when triggering external audio elements and visual subsystems, and for general data & MIDI processing. Percussive elements, rhodes, and additional audio processing in FL Studio.
