Get Free 909-style Drum Machine in your web browser


Extralife Instruments has just put the ER-99 right up in your grill/browser. Roland’s second most famous drum machine is emulated online.


Extralife Instruments has released a free online software emulation of Roland’s TR-909 drum machine.


All the drum sounds are generated using WebAudio API synthesis techniques, while the hi-hats, crash and ride cymbals are derived from samples. There’s a familiar interface, with the 16-step sequencer along the bottom and sound adjustment controls spread across the top.


In between there are various global controls. You can make your pattern up to four bars long, which equates to 64 steps, and adjust the tempo, accent, swing, compression and overall volume settings.


ER-99 comes with a selection of sequence and sound presets, and you can also create and save your own. You can take it for a spin on the Extralife Instruments website.
