We've seen drum machines and synthesizers that are playable in a browser before, but now one of the most iconic instruments has a more detailed web version. The HTML-808 and HTML5 Drum Machine made a virtual TR-808 easy to use with the likes of Chrome, Firefox and others. Debuting this week on 808 Day, the io-808 offers a lot more of the design, knobs, controls and functionality that the real drum machine employs. io-808 is the work of Vincent Jackson (a DJ whose real name is Vincent Riemer) using the Web Audio API to mimic the sounds of the physical 808. Sure, sounds aren't direct from samples, but they still sound quite good, especially for messing around in your cubicle at work.
