What's MIDI?

MIDI is an acronym that stands for Musical Instrument Digital Interface,

electronic musical instruments to communicate with each other, by sending and receiving performance infor-

mation.

Just what do we mean by "performance information"?

forms.

The pianist presses a key on a piano or presses a pedal.

These actions are instances of "performance information" and

reﬂect how the pianist played the instrument. MIDI is used to

capture and express this information electronically. When you

strongly play middle C on a MIDI keyboard, MIDI indicates the

key number as 60, and the strength of playing as 120, for exam-

ple. In this way, MIDI precisely describes your performance infor-

mation in digital form.

This performance information—MIDI data—can be

transmitted

between MIDI-compatible musical instruments, or

saved as a ﬁle for later playback. No matter what instrument or

computer you use, the MIDI data will reproduce the original per-

formance exactly the same. (Keep in mind that the actual sound

of the performance may differ from instrument to instrument—

for example, the acoustic piano sound on one instrument may

sound more full and rich than on another—but the basic perfor-

mance will be identical.)

The MIDI data saved as a ﬁle can easily be changed.

example, you can change an incorrectly played note to the cor-

rect one, change the song tempo, transpose the song to a desired

key, etc. This feature of MIDI is very effective for creating a song

or practicing with a musical instrument.
