I am trying to conceptualize how I would use reactive LED strips with sonic pi. The idea is to “attach” an LED strip to each sample and synth currently running, and make it glow more or less depending on the amplitude of the synth/sample. My question is whether it is possible to extract any properties from active synths, and if not how you would approach it. Is there a way to isolate the sound channels? Has anyone ever done anything like this before?
I have used reactive visuals before, such as plane9 and vsxu, and these use the currently playing sounds as a whole. I essentially want to do that, but separated into synths.
