Heyo! This was an experiement I did a while back to try and visualise sound into a coaster track using native cinema4d tools! I essentially used xpresso and the sound mograph tool to generate a spline to a specific section of music so that I could then fine tune it into a rollercoaster rail, i then took that spline into blender and used Eevee to render it out and make it all pretty :) This is actually suprisingly a quick and effective way to make a visual for music and I will 100% iterate on it in the future :) but maybe with signal or xparticles sound to drive the spline creation.
