    Drum machine · Japan

    The Roland TR-909 Rhythm Composer, introduced in 1983, is a drum machine that combined analog-synthesized drum voices with sampled cymbals and hi-hats. It added MIDI and a refined step sequencer, and its punchy kick, snappy snare, and bright hats became foundational to house and techno.
