Signal Synth is a real-time visual instrument built with Processing. Using a small set of geometric forms as its raw material, the sketch transforms simple shapes into evolving signals through rotation, feedback, oscillation, scaling, and automated parameter mutation. The result ranges from clean geometric studies to chaotic electronic-looking artifacts that feel somewhere between a vector oscilloscope, analog video feedback, and a modular synthesizer. Features include: • 9 geometric shape generators • Feedback-based drawing trails • Adjustable rotation, scale, stroke, and persistence controls • Independent sine-wave modulation of X position, Y position, and scale • Live glitch mode for introducing instability and jitter • Automated randomization engine for continuously evolving compositions • Black-on-white and white-on-black display modes • Full HUD for live performance and experimentation This sketch is part of my ongoing effort to release creative coding tools, experiments, instruments, and generative art systems built with Processing. Controls are included directly in the sketch HUD. If you enjoy this work, consider subscribing and joining my Patreon. I'm working toward releasing a new Processing sketch, creative coding experiment, or generative art tool every week. #processing #creativecoding #generativeart #processingorg #codeart #generativedesign #creativecodingart #algorithmicart #visualsynth #digitalart
