Musical Instrument Digital Interface

Musical Instrument Digital Interface (MIDI) is a technical standard that describes a communications protocol, digital interface, and electrical connectors and allows a wide variety of electronic musical instruments, computers and other related music and audio devices to connect and communicate with one another.A single MIDI link can carry up to sixteen channels of information, each of which can be routed to a separate device.

MIDI carries event messages that specify notation, pitch and velocity (loudness or softness), control signals for parameters such as volume, vibrato, audio panning from left to right, cues in theater, and clock signals that set and synchronize tempo between multiple devices.

Advantages of MIDI include :-

• small file size
• ease of modification and manipulation
• wide choice of electronic instruments and synthesizer or digitally-sampled sounds.
