Each track is a different method of synthesis. Subtractive, FM, additive, various physical models, etc. Made with Csound. They are all tuned to C2, I think. I've used these same samples in a number of canvases. This is one of the more chaotic emitter arrangements, it can be subtler, but I'm generally not a very subtle music maker. Changing emitters can make a huge difference. Give it a go!
