Drum machine

A drum machine is an electronic musical instrument designed to imitate the sound of drums or other percussion instruments. They are most commonly associated with electronic music, but are also used in many other genres. They are also a common necessity when session drummers are not available or desired. Most modern drum machines are sequencers with a sample playback or synthesizer component that specializes in the reproduction of drum timbres. Though features vary from model to model, many modern drum machines can also produce unique sounds, and allow the user to compose unique drum beats.
