Nice! What are your tricks?

I found that a longer second beat is traditionally more waltzy, but isn't always effective on pop music. Also, I added an option to accelerate the tempo. That is quite effective. For the sake of simplicity, I didn't add volume control, but it could help to turn the 3rd beat down a notch. Either way, I like the effect when the beat tracker doesn't fuck up.

You can easily mix audio and overlay sounds with Remix. Check in other examples. There's more design work necessary to make it truly convenient in the pure scripting sense, but you can get it done.
