List of music sequencers

Last updated

Music sequencers are hardware devices or application software that can record, edit, or play back music, by handling note and performance information.


Hardware sequencers

Many synthesizers, and by definition all music workstations, groove machines and drum machines, contain their own sequencers.

The following are specifically designed to function primarily as the music sequencers:

Analog-style step sequencers

Analog-style MIDI step sequencers

Since the analog synthesizer revivals in the 1990s, newly designed MIDI sequencers with a series of knobs or sliders similar to analog sequencer have appeared. These often equip CV/Gate and DIN sync interface along with MIDI, and even patch memory for multiple sequence patterns and possibly song sequences. These analog-digital hybrid machines are often called "Analogue-style MIDI step sequencer" or "MIDI analogue sequencer", etc.

Analog-style MIDI pattern sequencers

Several machines also provide "song mode" to play the sequence of memorised patterns in specified order, as per drum machines.

Step sequencers (supported on)

Typical step sequencers are integrated on drum machines, bass machines, groove machines, music production machines, and these software versions. Often, these also support the semi-realtime recording mode, too.

Embedded self-contained step sequencers

Several tiny keyboards provide a step sequencer combined with an independent timing mode for recording and performance:

  • Casio VL-Tone VL-1 (1979), Casiotone MT-70 (c.1984), Sampletone SK-1 (1986), etc.Timings of musical notes stored on the step sequencer, can be designated by the two trigger buttons labeled "One Key Play", around the right hand position

Embedded CV/Gate step sequencers

Several machines have white and black chromatic keypads, to enter the musical phrases.

Embedded MIDI step sequencers

Groovebox-type machines with white and black chromatic keypads, often support step recording mode along with realtime recording mode:

Other groovebox-type machines (including several music production machines) also often support step recording mode, of course:

Button-grid-style step sequencers

Recently emerging button-grid-style interfaces/instruments are naturally support step sequence. On these machines, one axis on grid means musical scale or sample to play, and another axis means timing of notes.

In addition, newly designed hardware MIDI sequencers equipping a series of knobs/sliders similar to analog sequencers, are appeared. For details, see #Analog-style MIDI step sequencers.

Digital sequencers


Also often support Gate clock and DIN sync interfaces.

A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds. This in contrast to older analog synthesizers, which produce music using analog electronics, and samplers, which play back digital recordings of acoustic, electric, or electronic instruments. Some digital synthesizers emulate analog synthesizers; others include sampling capability in addition to digital synthesis.

<span class="mw-page-title-main">Electronic musical instrument</span> Musical instrument that uses electronic circuits to generate sound

An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener.

<span class="mw-page-title-main">Music technology (electronic and digital)</span>

Digital music technology encompasses digital instruments, computers, electronic effects units, software, or digital audio equipment by a performer, composer, sound engineer, DJ, or record producer to produce, perform or record music. The term refers to electronic devices, instruments, computer hardware, and software used in performance, playback, recording, composition, mixing, analysis, and editing of music.

A music sequencer is a device or application software that can record, edit, or play back music, by handling note and performance information in several forms, typically CV/Gate, MIDI, or Open Sound Control (OSC), and possibly audio and automation data for digital audio workstations (DAWs) and plug-ins.

A software synthesizer or softsynth is a computer program that generates digital audio, usually for music. Computer software that can create sounds or music is not new, but advances in processing speed now allow softsynths to accomplish the same tasks that previously required the dedicated hardware of a conventional synthesizer. Softsynths may be readily interfaced with other music software such as music sequencers typically in the context of a digital audio workstation. Softsynths are usually less expensive and can be more portable than dedicated hardware.

<span class="mw-page-title-main">Modular synthesizer</span> Synthesizer composed of separate modules

Modular synthesizers are synthesizers composed of separate modules for different functions. The modules can be connected together by the user to create a patch. The outputs from the modules may include audio signals, analog control voltages, or digital signals for logic or timing conditions. Typical modules are voltage-controlled oscillators, voltage-controlled filters, voltage-controlled amplifiers and envelope generators.

A music workstation is an electronic musical instrument providing the facilities of:

<span class="mw-page-title-main">MIDI controller</span> Device that produces MIDI data

A MIDI controller is any hardware or software that generates and transmits Musical Instrument Digital Interface (MIDI) data to MIDI-enabled devices, typically to trigger sounds and control parameters of an electronic music performance. They most often use a musical keyboard to send data about the pitch of notes to play, although a MIDI controller may trigger lighting and other effects. A wind controller has a sensor that converts breath pressure to volume information and lip pressure to control pitch. Controllers for percussion and stringed instruments exist, as well as specialized and experimental devices. Some MIDI controllers are used in association with specific digital audio workstation software. The original MIDI specification has been extended to include a greater range of control features.

<span class="mw-page-title-main">Sound module</span> Externally controlled electronic musical instrument

A sound module is an electronic musical instrument without a human-playable interface such as a piano-style musical keyboard. Sound modules have to be operated using an externally connected device, which is often a MIDI controller, of which the most common type is the musical keyboard. Another common way of controlling a sound module is through a sequencer, which is computer hardware or software designed to record and playback control information for sound-generating hardware. Connections between sound modules, controllers, and sequencers are generally made with MIDI, which is a standardized interface designed for this purpose.

<span class="mw-page-title-main">Synthesizer</span> Electronic musical instrument

A synthesizer is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and may be synchronized to other equipment via MIDI.
