Oh, believe me, I know. That was my first and foremost complaint. When I was ranting about this back then, I decided to put my money where my mouth was by recreating a Roland/Boss drum machine in the browser - http://www.bitrotten.com/dr110 - I was also a bit rusty on my CSS & Javascript, and it was a good excuse to brush up there. There were a few annoyances I ran into along the way, but what leaves the concept dead in the water was the completely unstable clock. The only browser at the time that came even close to stable was Firefox, on a fairly speedy machine. Having proved my point (to myself) that Javascript wasn't ready, I've basically abandoned that project as something to revisit later as audio capabilities of web browsers become more robust. It's still easily a decade and a half behind Flash on that front.
