Musical Instrument Digital Interface (MIDI)

Protocol MIDI (Musical lnstrument Digital l17/efface) currently accepted and widely used by musicians and composers since the concept was introduced in 1982/1983. MIDI data is a standardized and efficient method for representing musical performance information, as it makes MIDI an attractive protocol not only for composers or performers to music but also for the application - a computer application that produces a sound like computer games or multimedia presentations.

Factors - factors such as the publication of General MIDI system specification, the interface compatibility between various PC/MIDI in common use, supporting facilities are accommodated MIDI computer operating systems like Microsoft Windows and also the evolution of low-cost music sintesiser, represents a significant impact on the widespread use of the MIDI protocol in various technological applications are also growing at this time.

MIDI data flow is the flow of bits can not simultaneously engaged in the same direction at 31.25 kbits / sec. with 10bits per byte transmission (start bit, 8 data bits and one stop bit). MIDI interface on a MIDI instrument usually has three different MIDI connector comprising IN, OUT and thru. MIDI data stream is usually initiated by a MIDI controller such as keyboard or MIDI sequencer. MIDI controller is a device used as a musical instrument musical performance that translates into a MIDI data stream in real time or real time (when played). Medium MIDI sequencer is a device which allows MIDI data sequences to the capture, store, edit, combine and replay. MIDI data output from a MIDI controller or sequencer is transmitted via MIDI OUT connector.

Recipients are generally anal MIDI data is a MIDI sound generator or sound module that will receive the message - a message on the MIDI IN connector MIDI messages and respond to it by playing tunes.
