Yup; crackles abound. I pulled it up in Chromium 24.0.1312.70 to see if the sound was any better, and (most of) the crackles are gone. When > 4 notes play you still get a bit of crackle, but it's far, far better. It's sad that everything HAS to be re-invented, but I am frequently excited to see what can be done with ES5. I'm eager to see what ES6 brings us.
