Roland TR-909

The Roland TR-909 Rhythm Composer is a partially analog, partially sample-based, drum machine introduced by the Japanese Roland Corporation in 1984. The brainchild of Tadao Kikumoto, the engineer behind the Roland TB-303, it features a 16-step step sequencer and a drum kit that aimed for realism and cost-effectiveness. It is fully programmable, and like its predecessor, the TR-808, it can store entire songs with multiple sections, as opposed to simply storing patterns. It was the first MIDI-equipped drum machine. Around 10,000 units were produced.

History

The 909 was launched three years after its 808 forebear, changing the game slightly by offering a part-analogue, part-sample-based sound generation hybrid. As with the 808, the 909 sounded a long way from the more realistic alternatives from Linn and Oberheim that had all but secured the upper ends of the drum machine market. As with the TB-303, the realism of the TR-909 was limited by technical constraints, and this showed when the machines were released at relatively low prices before its rise in popularity, coinciding with the beginnings of techno and acid. More expensive, sample-based drum computers were better at faithfully reproducing real drum sounds, while the TR-909 sounded synthetic.
