Between 1970 and the late 1990s, drum machines went from rhythm boxes built into home organs to the instruments that defined entire genres. The Roland TR-808 gave hip-hop its sub-bass kick. The LinnDrum put real recorded drums into pop records for the first time. The Oberheim DMX, the E-mu SP-1200, the Casio RZ-1: each one sounds the way it does because of the specific circuits and converters inside it, and none of them can be convincingly faked.
Most of these machines are long out of production, and the ones you can still buy cost thousands. But the sounds survive, sampled and preserved by collectors and archivists over decades.
This site makes all of them playable. Pick a machine below and it loads into a 16-step sequencer in your browser. No download, no account, nothing to install. Every sample is streamed from the Internet Archive's Drum Machines Collection, 48,572 samples across 470 machines, and you can audition any individual sound before you use it.
