This is the version that stores the files locally and also has the tempo fixed (bpm instead of milliseconds between notes). Also we keep the old tempo after a set of notes and tempo have been submitted.

Changed it back to having the sound files online instead of stored locally, because for some reason when stored locally they occasionally (very rarely but noticeably sometimes) don't play when they're supposed to.

Also the tempo is set to bpm instead of milliseconds between. And the old tempo is stored instead of returning to default.

So now the sound files are back to referencing mp3s from tumblr.com

I figured out how to make the sounds and images be local instead of your browser having to go access them from where I posted them on tumblr!
