Check out this awesome HTML5 TR-808 Drum Machine!
“For the aspiring DJs and living room producers, there’s now a way to craft your drum machine chops with nothing more than your favorite web browser. An HTML5-driven site lets you choose between iconic instruments like Roland’s TR-808 and TR-909, alongside Elektron’s Machinedrum, the LinnDrum and a regular ol’ acoustic kit for the luddites. In addition to turning nobs to get the perfect sound, you can save samples for use during your next studio session. What’s more, when you’re all finished, the site allows you to export loops as a WAV file that can be employed in a more robust production app. If you’ll recall, there’s also a web-based MPC that’ll let you try your hand at piecing together samples used by J Dilla and Kanye West. With these two tools in your browser, there’s really no excuse for not exploring that music habit.”
