MIDI is a common form of electronic music. MIDI (http://www.aliyun.com/zixun/aggregation/6141.html ">musical instrument Digital Interface) musical Instrument Digital interface, is 20th century 80 At the beginning of the year to solve the problem of communication between electro-acoustic instruments proposed. MIDI transmission is not a sound signal, but notes, control parameters, and other instructions, it indicates what the MIDI device to do, how to do, such as playing which note, how much volume. They are uniformly represented as MIDI messages (MIDI message). The transmission adopts asynchronous serial communication, and the standard communication baud rate is 31.25x (1±0.01) Kbaud.
MIDI is just a communication standard, established by instruments manufacturers to determine how computer music programs, synthesizers, and other electronic audio Devices exchange information and control signals.
MIDI system is actually a composing, orchestration, electronic simulation of the performance system. The data transferred from one MIDI device to another MIDI device is MIDI information. MIDI data is not a digital audio waveform, but a musical code or an electronic sheet music.
