A specific MIDI Implementation Chart is published for each MIDI device.

* Roland MT-32 MIDI Implementation

The game's own CD contained soundtrack in audio format that was exactly the same as the game's MIDI soundtrack but played through a high quality sound module.

MIDI technology was standardized by a panel of music industry representatives, and is maintained by the MIDI Manufacturers Association ( MMA ).

By the time of the January 1983 Winter NAMM Show, Smith was able to demonstrate a MIDI connection between his Prophet 600 analog synthesizer and a Roland JP-6.

The MIDI Specification was published in August 1983.

MIDI was invented so that musical instruments could communicate with each other, and that one instrument can control another.

The Atari ST was favored for its MIDI ports that were built directly into the computer.

The low-fidelity reproduction of these ubiquitous cards was often assumed to somehow be a property of MIDI itself.

MIDI was designed with keyboards in mind, and any controller that is not a keyboard is considered an " alternative " controller.

This was seen as a limitation by composers who were not interested in keyboard-based music, but the standard proved flexible, and MIDI compatibility was introduced to other types of controllers, including wind instruments and drum machines.

The first low-cost MIDI sampler was the Ensoniq Mirage, introduced in 1984.

Examples include " note-on " messages which contain a MIDI note number that specifies the note's pitch, a velocity value that indicates how forcefully the note was played, and the channel number ; " note-off " messages that end a note ; program change messages that change a device's patch ; and control changes that allow adjustment of an instrument's parameters.

The General MIDI ( GM ) standard was established in 1991, and provides a standardized sound bank that allows a Standard MIDI File created on one device to sound similar when played back on another.

The MIDI Tuning Standard ( MTS ) was ratified in 1992, and provides a set of SysEx messages that allow alternate tunings.

A standard for MIDI over USB was developed in 1999 as a joint effort between IBM, Microsoft, Altec Lansing, Roland Corporation, and Philips.

It was conceived as a Local Area Network for musical instruments, with FireWire as the transport, and was designed to carry multiple channels of MIDI together with multichannel digital audio, data file transfers, and time code.

A new version of MIDI with full backward compatibility has been under discussion since 2005, when it was announced as " HD-MIDI ".

The 68EC000 was used as a controller in many audio applications, including Ensoniq musical instruments and sound cards where it was part of the MIDI synthesizer.

It was a very important device at that time, allowing drummers and percussionists the opportunity to trigger virtually any MIDI sound source without the need of a full electronic drum set.

Again the Pad-80 was an eight pad MIDI controller that allowed for various types of MIDI sound sources.

* General MIDI, a standardized specification for music synthesizers

The Standard MIDI File ( SMF ) is a file format that provides a standardized way for sequences to be saved, transported, and opened in other systems.

General MIDI or GM is a standardized specification for music synthesizers that respond to MIDI messages.

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.

Through signal generation, voice and instrument-level processing, a signal flow is created and controlled either by MIDI capabilities or voice and instrument-level controls.

Rackmounts are controlled by knobs or switches on their front panel, and often by a MIDI digital control interface.

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 creative possibilities brought about by MIDI technology have been credited as having helped to revive the music industry in the 1980s.

Computer-aided learning enabled by MIDI has transformed the way technology is used in music education.

When a MIDI continuous controller number is assigned to one of these parameters, the device will respond to any messages it receives that are identified by that number.

A set of adjusted parameters can be saved to a device's internal memory as a " patch ", and these patches can be remotely selected by MIDI program changes.

The MIDI standard allows selection of 128 different programs, but devices can provide more by arranging their patches into banks of 128 programs each, and combining a program change message with a bank select message.

Some composers may take advantage of MIDI 1. 0 and General MIDI ( GM ) technology to allow musical data files to be shared among various electronic instruments by using a standard, portable set of commands and parameters.

Virtual Instruments created by third party companies in one of a number of commonly used formats ( for example, VST or RTAS ) may be loaded as plug-ins thus providing a virtually limitless supply of sounds for a musician, and are designed to be commanded by MIDI controllers, especially in the DAW environment.

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.

Sequencers may take alternate forms, such as drum pattern editors that allow users to create beats by clicking on pattern grids, and loop sequencers such as ACID Pro, which allow MIDI to be combined with prerecorded audio loops whose tempos and keys are matched to each other.

Routing setups can be created using computer software, stored in memory, and selected by MIDI program change commands.

Some computer sound cards include a standard MIDI connector, whereas others connect by any of various means that include the D-subminiature DA-15 game port, USB, FireWire, Ethernet or a proprietary connection.

GM was developed by the MIDI Manufacturers Association ( MMA ) and the Japan MIDI Standards Committee ( JMSC ) and first published in 1991.

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 ).

This Forum created the MSC standard between January and September, 1990. it was ratified by the MIDI Manufacturers Association ( MMA ) in January, 1991, and the Japan MIDI Standards Committee ( JMSC ) later that year, becoming a part of the standard MIDI specification in August, 1991.
