MIDI (Musical Instrument Digital Interface) Musical Instrument Digital Interface was put forward in the early 1980s to solve the communication problem between electroacoustic instruments. MIDI is the most extensive music standard format in the field of arrangement, which can be called "computer-understandable music score".

Almost all modern music is synthesized by MIDI and sound library. MIDI transmits not sound signals, but notes, control parameters and other instructions, which indicate what MIDI devices should do and how to do it, such as which note to play and how loud the sound is. They are uniformly represented as MIDI messages.

The application of MIDI

The music director of TV evening can use MIDI function to assist music creation, or generate music data media according to MI-DI standard, or play music directly.

If the computer is equipped with an advanced MIDI software library, music creation, score printing, programming, music adjustment, sound amplitude, rhythm, coordination between parts and reverberation can all be controlled by MIDI.

Using MIDI technology to connect electronic synthesizer, electronic rhythm machine (electronic drum machine) and other electronic sound sources with sequencer, we can play and simulate magnificent sound effects with varied timbres, and also store various key data in the performance, which greatly improves the ability and conditions of music performance.
