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.
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 Roland TR-909 Rhythm Composer, commonly known as the 909, is a drum machine introduced by Roland Corporation in 1983, succeeding the TR-808. It was the first Roland drum machine to use samples for some sounds, and the first with MIDI functionality, allowing it to synchronize with other devices. Though a commercial failure, it influenced the development of electronic dance music genres such as techno, house and acid house.
The Roland MC-303 is the first of a series of musical instruments known as a groovebox. It combines a simple sound module with a sequencer to record and store notation, along with controls aimed at encouraging the musician to improvise the music while it is playing. Despite the number in its name and the attention it received at its launch, the MC-303 has more in common with other MC prefixed synthesizers, which contain built-in sequencers, than it does with the famous Roland TB-303. As the first Groovebox, the MC-303 was the first in a line of inexpensive products specifically targeted towards house DJs and amateur home musicians rather than professional producers. It was superseded by the Roland MC-505. It is the predecessor to the Roland JX-305, Roland D2, Roland MC-307, Roland EG-101, Roland MC-09, Roland MC-909, Roland MC-808, and most recently the Roland MC-707 in 2019, along with its more portable sibling, the Roland MC-101.
The Roland MT-32 Multi-Timbre Sound Module is a MIDI synthesizer module first released in 1987 by Roland Corporation. It was originally marketed to amateur musicians as a budget external synthesizer with an original list price of $695. However, it became more famous along with its compatible modules as an early de facto standard in computer music. Since it was made prior to the release of the General MIDI standard, it uses its own proprietary format for MIDI file playback.
The Yamaha AN1x is a DSP-based analog modeling synthesizer, produced by Yamaha Corporation from 1997 to 1998, and was marketed as an "analog physical modelling control synthesizer".
The Roland MC-505 is a groovebox conceived in 1998 as a combination of a MIDI controller, a music sequencer, a drum machine, and a desktop synthesizer with many synthesis features: arpeggiator, oscillators, and voltage-controlled filter, control of attack, decay, sustain and release, different envelopes and 2 Lfo. It was released as the successor to the Roland MC-303 and is a compact version of the Roland JX-305 Groovesynth without the full set of 61 keys. It is also the predecessor to the Roland D2, Roland MC-307, Roland MC-909 and the Roland MC-808.
The Roland Jupiter-4 (JP-4) was an analog synthesizer manufactured by the Roland Corporation between 1978 and 1981. It was notable as the company's first self-contained polyphonic synthesizer, and for employing digital control of analog circuits, allowing for such features as programmable memory, voice assignment modes, an arpeggiator, polyphonic portamento and others.
The MC-808 is a groovebox introduced by Roland in 2006. It is the successor to the late Roland MC-303, Roland MC-307, Roland MC-505 and Roland MC-909.
The Alesis Ion is an analog modeling synthesizer. It was announced during the NAMM Summer Session in 2002. Unlike the Alesis Andromeda, Alesis's analog synthesizer, its sounds are synthesized using DSP chips to mimic the sound of analog audio circuitry and components.
The Boss DR-110 Dr. Rhythm is a drum machine introduced in 1983 by the Boss product division of the Japanese Roland Corporation. It was the second entry in their DR series, following up on the much simpler DR-55.
The R-8 Human Rhythm Composer is an electronic drum machine introduced in 1989 by Roland Corporation, using PCM voices. The R-8 features velocity- and pressure-sensitive trigger pads, and the ability to create loops of beats. The device has eight individual outputs, 12-voice polyphony, and four-part multitimbral MIDI.
Casio's SDSynthesizers were a late-1980s line of analog synthesizers featuring a resonant filter. SD synthesis was traditional DCO-analog synthesis, with the main difference being that some of the SD waveforms' harmonic spectrums changed temporally, or dynamically in relation to the amplitude envelope.
The Roland Alpha Juno is a series of analog polyphonic synthesizers introduced by Roland Corporation in 1985. The Alpha Juno 1 and Alpha Juno 2 were released at the same time, and feature the same sound engine but with the latter boasting additional performance features. The Alpha Junos were a departure from their predecessor, the Roland Juno-106, as they replaced the dedicated controls with soft touch buttons and a single dial for programming sounds. One of the factory presets, nicknamed a 'hoover sound', became a staple in jungle and rave music.
The Sirius is a keyboard "groove-synth," featuring a subtractive hybrid-tone-generation synthesizer referred to as DTE synthesis introduced in 1997 by Quasimidi. The unit featured both real-time and step sequencers with pattern- and song-modes, capable of acting basic drum machine, groove-box, or sound-module.
The Roland JX-305 Groovesynth synthesizer was produced in 1998 by Roland. It is very similar to a Roland MC-505 with an additional set of 61 keys. The keyboard is sensitive to velocity and has channel aftertouch. This keyboard was aimed at producers of dance and trance music and was also popular for live performances during the late 1990s.
The Mini Pops were a number of early analog drum machines from the Japanese musical equipment company Korg during the late 1960s and the 1970s. The machines were based around a number of preset rhythm patterns, such as waltz, samba, rhumba, bossa nova, tango, slow rock, swing, and rock 1 and 2.
The Boss DR-220 Dr. Rhythm is a series of two budget-priced digital drum machines developed and manufactured by Boss Corporation beginning in 1985.
The Roland D2 Groovebox is a performance-oriented Groovebox. It has Roland's D-Field Controller technology. It has all of the Roland MC-505 sounds and a similar sequencer. All of the MFX effects have sub-menus. The D2 has 100+ sub-menus to sub-sub-sub-menus, and this is why it has fewer buttons than other Grooveboxes.
