MIDI (; short for Musical Instrument Digital Interface ) is an electronic musical instrument industry specification that enables a wide variety of digital musical instruments, computers and other related devices to connect and communicate with one another.

All official MIDI standards are jointly developed and published by the MMA in Los Angeles, California, USA, and for Japan, the MIDI Committee of the Association of Musical Electronics Industry ( AMEI ) in Tokyo.

The draft working version of ZIPI was primarily aimed at addressing many limitations of MIDI ( Musical Instrument Digital Interface ).

The official specification is available in English from the MMA, bound together with the MIDI 1. 0 specification, and in Japanese from the Association of Musical Electronic Industry ( AMEI ).

MIDI ( Musical Instrument Digital Interface ) is a digital current loop interface.

The following are classes of MIDI ( Musical Instrument Digital Interface ) controller:

* MIDI Musical Instrument Digital Interface allows a variety of musical instruments to interact with the PC in a digital environment for recording or performance.

* Musical Instrument Digital Interface ( MIDI ) player, real-time on some targets.

Connections between sound modules, controllers, and sequencers are generally made with MIDI ( Musical Instrument Digital Interface ), which is a standardized protocol designed for this purpose.

This variation was accomplished through a custom Musical Instrument Digital Interface ( MIDI ) driver, which altered music based on signals from the game engine.

After some enhancements and revisions, the new standard was introduced as " Musical Instrument Digital Interface " ( MIDI ) at the Winter NAMM Show in 1983, when a Sequential Circuits Prophet-600 was successfully connected to a Roland Jupiter-6.

Digital Audio Workstations ( DAW ) are becoming one of the most centric and common tools in the studio, and many are specifically designed to work with MIDI as an integral component.

In protest against legislation that prohibits publication of copy protection circumvention code in countries that implement the WIPO Copyright Treaty ( such as the United States ' Digital Millennium Copyright Act ), some have devised clever ways of distributing descriptions of the DeCSS algorithm, such as through steganography, through various Internet protocols, on t-shirts and in dramatic readings, as MIDI files, as a series of haiku poems, and even as a so-called illegal prime number.

Popular audio-recording software includes Apple Logic Pro, Digidesign's Pro Tools — near standard for most professional studios — Cubase and Nuendo both by Steinberg, MOTU Digital Performer — popular for MIDI.

Digital pianos usually offer a MIDI connection, allowing them to control or be controlled by other electronic instruments and sequencers.

Akai also produced several Digital MIDI sequencers and digital synthesizers such as the MPC range ( Music Production Center ), a line of integrated drum machines, MIDI sequencers, samplers and direct-to-disk recorders that resemble drum machines.

The Akai MPC60 Digital Sampler / Drum Machine and MIDI Sequencer ( 1988 ) was the first non-rack mounted model released.

These modules can be controlled from Reason's built-in MIDI sequencer or from other sequencing applications such as Pro Tools, Logic, FL Studio, Digital Performer, Cubase, Sonar, and GarageBand via Propellerhead's ReWire protocol in the 32-bit versions of these software.

While MIDI is a fairly ubiquitous standard for representation of digital music, there is no broadly accepted standard for the interchange of complete projects containing both MIDI and audio between Cubase and other competing recording / editing software ( e. g. Logic Pro, Pro Tools, Digital Performer, or Cakewalk ), so while actual pure recorded audio information can be exchanged, it is hard to import a whole project ( with specific edits, instrument information and automation ) in its native format from Cubase to another application and vice versa.

Most notably, it does not include MIDI sequencing capabilities, and thus does not include some of Digital Performer's MIDI-specific editing windows.

FireWire's high data bandwidth made it not only a suitable transmission medium for MIDI data, but also a replacement for the SCSI and IDE hard drive buses and ADAT Optical Interface audio transmission.

The MPEG-4 Part 3 consists of a variety of audio coding technologies-from lossy speech coding ( HVXC, CELP ), general audio coding ( AAC, TwinVQ, BSAC ), lossless audio compression ( MPEG-4 SLS, Audio Lossless Coding, MPEG-4 DST ), a Text-To-Speech Interface ( TTSI ), Structured Audio ( using SAOL, SASL, MIDI ) and many additional audio synthesis and coding techniques.

* Steinberg Media Interface 4 ( MI4 )-USB MIDI interface

** MC6850P ACIA " Asynchronous Common Interface Adapter " — Enabled the ST to directly communicate with MIDI devices and keyboard ( 2 chips used ).

* Interface protocols ( e. g. MIDI ) and alternative controllers

By means of the ENGL MIDI Interface ( optional ), these features can be controlled via a MIDI pedal board and the settings for switching functions can be programmed in up to 99 memory locations.

Since the invention of the MIDI system in the early 1980s, for example, some people have worked on programs which map MIDI notes to an algorithm and then can either output sounds or music through the computer's sound card or write an audio file for other programs to play.

Further, the data composed via the sequenced MIDI recordings can then be saved as a Standard MIDI File ( SMF ), digitally distributed, and reproduced by any computer or electronic instrument that also adheres to the same MIDI, GM, and SMF standards.

Such programs allow the user to record acoustic sounds or MIDI musical sequences, which may then be organized along a time line.

As with many other styles of music, many Soca drum sections are recorded today using synthesized drum sounds and then sequenced inside computers ; however, for live shows, the live human drummer emulates the recorded version and often triggers the same sound samples via advanced technological configuration ( like MIDI ).

He retired from active performing and touring in late 1996, after having performed his last concert at William Paterson College on November 10, 1996, then choosing to stay at his home in Indianapolis where he could indulge his passion of composing and arranging music with computers and MIDI.

The values calculated by these sensors are then converted into MIDI data which gives a velocity value for each note, which is usually directly proportional to amplitude of the note when played.

As noted above, " Cakewalk " was the name of the company's original product, a MIDI sequencer first released for DOS and then, beginning in 1991, for Windows 3. 0.

This allowed users to record music either as MIDI and / or Audio in freetime, without click or metronome, and then move the bars and beats grid to the music, automatically creating a tempo track.

The JP-6 was among the first electronic instruments ( alongside the Roland JX-3P and the Sequential Circuits Prophet-600 ) to feature MIDI, then a brand new technology.

In the 1980s, UZEB had what was then a very technologically advanced MIDI system for its synthesizers.

After the pedalboard is cleaned up and the glass reed switches are repaired or replaced, the pedal contacts are soldered into a keyboard matrix circuit-equipped MIDI encoder, which can then be connected to the MIDI input of a digital sound module to create a bass organ tone.

HardSID's major advantage over SidStation ( apart from the fact that the SidStation has been sold out long since, with only few used pieces surfacing now and then ) is that it is a simple hardware interface to a SID chip, making it far more suitable for emulator use, SID music players and even direct programming-SidStation only responds to MIDI information and requires music events to be converted to MIDI and back.

Most MIDI sequencers presented a song as a linear set of tracks ; however, Notator and Vision were pattern-based sequencers: songs were built by recording patterns ( which might represent for example Intro, Verse, Chorus, Middle-8, Outro ) with up to 16 tracks each, then assembling an Arrangement of these patterns, with up to 4 patterns playing simultaneously at any one point in the song.

This, combined with a relatively cheap four track tape machine or higher end 16 and 24 track reel-to-reel machines would allow a musician to layer a number of keyboard tracks digitally, and then use a single track for MIDI information and the rest for analogue sounds, without requiring intermediate mix-downs to gain additional needed synth tracks.

The sounds recorded by any device, and then transferred to digital format are used by some musicians through their performance with MIDI interfaced instruments.

In the MIDI controller, this analog DC current interruption is converted to a digital signal, which is then used to trigger many possible events or actions.

The harpist may then proceed to transfer his or her composition by connecting the MIDI harp to a computer ( preferably a PC ).
