A Geometry Nodes setup that functions as an audioreactive instancer and visualizer. It instances geometry frame by frame along a custom guide curve, scaling the objects based on audio data baked to an F-curve. The system relies on simulation zones to generate and accumulate instances over time. Built with readability in mind, the node tree is kept simple for educational dissection. Users can customize the base curve, the instanced objects, scaling interpolation, and material properties like emission glow. While designed primarily for audio reactivity, the instancing logic can also be driven by standard manual keyframes. The included scene is optimized for Eevee.
