MIDI in the context of "List of electronic music genres"

A scorewriter, or music notation program is software for creating, editing and printing sheet music. A scorewriter is to music notation what a word processor is to text, in that they typically provide flexible editing and automatic layout, and produce high-quality printed results.

The first modern score manipulation program was Mockingbird, written by John Maxwell and Severo Ornstein at Xerox PARC in 1980 on a Dorado computer. It preceded MIDI so an electronic keyboard had to be modified to enable interaction (input and playback) with the program. The WYSIWYG program was envisioned as a composer's amanuensis, but as it was an experimental program it never reached beyond PARC, though it influenced commercial programs which soon followed.

A synthesizer (also synthesiser or synth) 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 can be synchronized to other equipment via MIDI.

Synthesizer-like instruments emerged in the United States in the mid-20th century with instruments such as the RCA Mark II, which was controlled with punch cards and used hundreds of vacuum tubes. The Moog synthesizer, developed by Robert Moog and first sold in 1964, is credited for pioneering concepts such as voltage-controlled oscillators, envelopes, noise generators, filters, and sequencers. In 1970, the smaller, cheaper Minimoog standardized synthesizers as self-contained instruments with built-in keyboards, unlike the larger modular synthesizers before it.

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.

An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch, frequency, or duration of each note. A common user interface is the musical keyboard, which functions similarly to the keyboard on an acoustic piano where the keys are each linked mechanically to swinging string hammers - whereas with an electronic keyboard, the keyboard interface is linked to a synth module, computer or other electronic or digital sound generator, which then creates a sound. However, it is increasingly common to separate user interface and sound-generating functions into a music controller (input device) and a music synthesizer, respectively, with the two devices communicating through a musical performance description language such as MIDI or Open Sound Control. The solid state nature of electronic keyboards also offers differing "feel" and "response", offering a novel experience in playing relative to operating a mechanically linked piano keyboard.

A pedalboard (also called a pedal keyboard, pedal clavier, or, with electronic instruments, a bass pedalboard) is a keyboard played with the feet that is usually used to produce the low-pitched bass line of a piece of music. A pedalboard has long, narrow lever-style keys laid out in the same semitone scalar pattern as a manual keyboard, with longer keys for C, D, E, F, G, A, and B, and shorter, raised keys for C♯, D♯, F♯, G♯ and A♯. Training in pedal technique is part of standard organ pedagogy in church music and art music.

Pedalboards are found at the base of the console of most pipe organs, pedal pianos, theatre organs, and electronic organs. Standalone pedalboards such as the 1970s-era Moog Taurus bass pedals are occasionally used in progressive rock and fusion music. In the 21st century, MIDI pedalboard controllers are used with synthesizers, electronic Hammond-style organs, and with digital pipe organs. Pedalboards are also used with pedal pianos and with some harpsichords, clavichords, and carillons (church bells).

An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument based on keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a rompler-based synthesizer with a low-wattage power amplifier and small loudspeakers.

Electronic keyboards offer a diverse selection of instrument sounds (piano, organ, violin, etc.) along with synthesizer tones. Designed primarily for beginners and home users, they generally feature unweighted keys. While budget models lack velocity sensitivity, mid-range options and above often include it.  These keyboards have limited sound editing options, focusing on preset sounds. Casio and Yamaha are major manufacturers in this market, known for popularizing the concept since the 1980s.

Daniel Lopatin (born July 25, 1982), best known as Oneohtrix Point Never or OPN, is an American electronic music producer, composer, singer, and songwriter. His work experiments with tropes from an eclectic range of musical genres and eras, and has featured sample-based composition and complex MIDI production. He began releasing music in the 2000s, and received early acclaim for the synthesizer-based compilation Rifts (2009) as well as the influential vaporwave side-project Chuck Person's Eccojams Vol. 1 (2010).

Lopatin signed with Warp in 2013, and has since released studio albums on the label to positive critical reception. He has also contributed production work to various artists, most extensively the Weeknd, Moses Sumney, and Soccer Mommy. He has composed scores for films such as Good Time (2017), Uncut Gems (2019), and Marty Supreme (2025); the first won him the Soundtrack Award at the 2017 Cannes Film Festival.

A music sequencer (or audio sequencer or simply 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, and possibly audio and automation data for digital audio workstations (DAWs) and plug-ins.

A piano roll is a music storage medium used to operate a player piano, piano player or reproducing piano. Piano rolls, like other music rolls, are continuous rolls of paper with holes punched into them. These perforations represent note control data. The roll moves over a reading system known as a tracker bar; the playing cycle for each musical note is triggered when a perforation crosses the bar.

Piano rolls have been in continuous production since at least 1896, and are still being manufactured today; QRS Music offers 45,000 titles with "new titles being added on a regular basis", although they are no longer mass-produced. MIDI files have generally supplanted piano rolls in storing and playing back performance data, accomplishing digitally and electronically what piano rolls do mechanically. MIDI editing software often features the ability to represent the music graphically as a piano roll.

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 (Musical Instrument Digital Interface), which is a standardized interface designed for this purpose.

Sound modules are often rack-mountable, but are also produced in table-top form factor, particularly when the intended user is a DJ or record producer. The height of a sound module is often described in rack units. Small sound modules are mostly 1U in height, the larger models a multiplication e.g. 2U or 3U. Despite their name, most sound modules do not produce any audible sound until their output is plugged into a keyboard amplifier or a PA system.

A MIDI controller is an input device and electronic musical instrument which typically converts physical interaction to Musical Instrument Digital Interface (MIDI) information. This information can be sent to a sound module, synthesizer, or sampler, or can be recorded using a music sequencer or digital audio workstation for later playback. A MIDI controller may or may not have a synthesizer or speaker built in, and most rely on external equipment to convert MIDI events into an audio signal and then into audible sound.

Often, MIDI controllers resemble traditional musical instruments. The most common type is the MIDI keyboard, which resembles a keyboard instrument like a piano, but parallels for a range of instruments exist, including wind controllers which resemble wind instruments, guitar-like controllers such as the SynthAxe, and electronic drum kits which mimic acoustic drums. There are also some controllers without acoustic parallels, the most common being MIDI-enabled music sequencers and simple drum pad controllers like the Roland Octapad, Korg PadKontrol and Novation Launchpad.

A networked music performance or network musical performance is a real-time interaction over a computer network that enables musicians in different locations to perform as if they were in the same room. These interactions can include performances, rehearsals, improvisation or jamming sessions, and situations for learning such as master classes. Participants may be connected by "high fidelity multichannel audio and video links" as well as MIDI data connections and specialized collaborative software tools. While not intended to be a replacement for traditional live stage performance, networked music performance supports musical interaction when co-presence is not possible and allows for novel forms of music expression. Remote audience members and possibly a conductor may also participate.

The game port is a device port that was found on IBM PC compatible and other computer systems throughout the 1980s and 1990s. It was the traditional connector for joystick input, and occasionally MIDI devices, until made obsolete by USB in the late 1990s.

Originally located on a dedicated Game Control Adapter expansion card, the game port was later integrated with PC sound cards, and still later on the PC's motherboard. During the transition to USB, many input devices used the game port and a USB adapter dongle was included for systems without a game port.

Roland Corporation (ローランド株式会社, Rōrando Kabushiki Kaisha) is a Japanese multinational manufacturer of electronic musical instruments, electronic equipment, and software. It was founded by Ikutaro Kakehashi in Osaka in 1972. In 2005, its headquarters relocated to Hamamatsu in Shizuoka Prefecture. It has factories in Malaysia, Taiwan, Japan, and the United States. As of December 2022, it employed 2,783 people. In 2014, it was subject to a management buyout by its CEO, Junichi Miki, supported by Taiyo Pacific Partners.

Roland has manufactured numerous instruments that have had lasting impacts on music, such as the Juno-106 synthesizer, TB-303 bass synthesizer, and TR-808 and TR-909 drum machines. It was also instrumental in the development of MIDI, a standardized means of synchronizing electronic instruments manufactured by different companies. In 2016, Fact wrote that Roland had arguably had more influence on electronic music than any other company.
