The Linn LM-1 Drum Computer is a drum machine manufactured by Linn Electronics and released in 1980. It was the first drum machine to use samples of acoustic drums, and one of the first programmable drum machines. Its designer, the American engineer Roger Linn, wanted a machine that would produce more realistic drum sounds and offer more than preset patterns.

A drum machine is an electronic musical instrument that creates percussion sounds, drum beats, and patterns. Drum machines may imitate drum kits or other percussion instruments, or produce unique sounds, such as synthesized electronic tones. A drum machine often has pre-programmed beats and patterns for popular genres and styles, such as pop music, rock music, and dance music. Most modern drum machines made in the 2010s and 2020s also allow users to program their own rhythms and beats. Drum machines may create sounds using analog synthesis or play prerecorded samples.
