Nice job!

As we talked on Reddit (I released my synth today, Viktor NV-1: http://nicroto.github.io/viktor/) I definitely need to add QWERTY keyboard playability.

Also - url sharing of presets... that's a great idea! Viktor uses local storage so you can save presets and allows you to export and import libraries of presets (in json files), but file sharing is harder than a url.

I think there is something wrong with the way your envelope works, though. I hear clipping when I change notes. In my case it took a lot of time tuning the envelope, before it became really playable through a keyboard and still as you know, in Firefox there is an issue with AudioParam.setTargetAtTime starting or arriving at a value close to 0.

Congrats on making #1 page on HN. Couple of hours after you, my submission didn't even get an upvote. :P
