Roland TR-909

The TR-909 was a mostly-analogue drum machine made by Roland in the mid 1980s.

It retained much of the TR-808's subtle timbre tweakability, along with its individual outputs, making it ideal in the studio. In addition to having more weighty sounds, the TR-909 also added separate accents for each sound, flams, and shuffle/swing.

Best of all, it used MIDI. For people who wanted to program their drums via a controller keyboard and a home computer based sequencer, this rendered the onboard sequencer's improvements a moot issue — they would use it only for its sounds, which were sensitive to the full MIDI range of velocities and timing, making it as versatile as whichever MIDI sequencer was controlling it.

When it was released, people were disappointed that it didn't exclusively use digital samples, which would have sounded more realistic. It was later venerated as a stylised classic, along with the TR-808. It's been extensively sampled and cloned, and even if you haven't heard of it, its sounds will very likely already be familiar to you.


Derrick sold Chicago DJ Frankie Knuckles a TR-909 drum machine. This was back when the Power Plant was open in Chicago, but before any of the Chicago DJs were making records... One thing just led to another, and Chip E used the 909 to make his own record, and from then on all these DJs in Chicago borrowed that 909 to come out with their own records.

Everybody was using Kevin's 909, and you can imagine how that was. It was just never available. When you did get a chance to use it, the next day somebody was calling up for it. Derrick just recently lucked up on one, and I hope to find one for myself when I get back to Detroit.

When Roland discontinued the 808 and 909 to come out with the 707 and 505, they tried to come out with a more true drum sound, but the whole beauty of Roland was that they had drum sounds which were different from everybody else's.

— Juan Atkins, 1988[1]
