// Most of your ditty will run 44100 times per second using javascript in the browser.
// Make sure you optimize your ditty to work well on as many devices as possible. To do that, try to limit
// the number of simultaneously active synths: make sure they don't last longer than necessary, or you can
// hear them, and spread them over different loops (each loop runs in a separate worker).
