Analog synthesizer in the context of "Moog synthesizer"

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.

While a distinction is generally made between drum machines (which can play back pre-programmed or user-programmed beats or patterns) and electronic drums (which have pads that can be struck and played like an acoustic drum kit), there are some drum machines that have buttons or pads that allow the performer to play drum sounds "live", either on top of a programmed drum beat or as a standalone performance. Drum machines have a range of capabilities, which go from playing a short beat pattern in a loop, to being able to program or record complex song arrangements with changes of meter and style.

The Roland TR-808 Rhythm Composer, commonly known as the 808, is a drum machine manufactured by Roland Corporation between 1980 and 1983. It was one of the first drum machines to allow users to program rhythms instead of using preset patterns. Unlike its nearest competitor at the time, the more expensive Linn LM-1, the 808 generates sounds using analog synthesis rather than by playing samples.

The 808 was a commercial failure, as electronic music had yet to become mainstream and many producers wanted more realistic drum sounds. After building approximately 12,000 units, Roland discontinued the 808 after its semiconductors became impossible to restock. It was succeeded by the TR-909 in 1983.

The Minimoog is an analog synthesizer introduced by Moog Music in 1970. Designed as a more affordable, portable version of the modular Moog synthesizer, it was the first synthesizer sold in retail stores. It was first popular with progressive rock and jazz musicians and found wide use in disco, pop, rock and electronic music. In 2005, the Minimoog was inducted into the TECnology Hall of Fame.

Production of the Minimoog stopped in the early 1980s after the sale of Moog Music. In 2002, the founder, Robert Moog, regained the rights to the Moog brand, bought the company, and released an updated model, the Minimoog Voyager. In 2016 and 2022, Moog Music released newer versions of the original model.
