The Web Audio Drum Machine is a great sounding free online drum machine with 6 rhythm tracks, as well as multiple presets, kits and effects and a small but useful collection of mix and tweak settings. It’s a perfect way to get a beat quickly out of your brain and into your earlobes. You can save your patterns and revisit them later online by loading them up again, but if you’re serious about your beats, you’re going to need to work out some way of recording them as a sample for your mixdown studio or sequencer.
