Audio and video produced with simple feedback patches using my Eurorack analogue modular synthesiser. Organic textures and artefacts emerge from relatively simple feedback systems. The video is sped up 200% from the original capture, otherwise there is no software post-processing.
No input signal generation in the video patch. Audio-wise has almost no input but I would sometimes inject a tone to ‘seed’ the feedback loop of the audio signal patch if it ebbed away. What you’re seeing & hearing is primarily the effect of the feedback loop amplifying the analogue video and audio circuitry from the synthesiser.
