What's MIDI?

Let's consider an acoustic piano and a classical guitar as
RS422
representative acoustic instruments. With the piano, you
strike a key, and a hammer inside hits some strings and
MINI DIN
8-pin
plays a note. With the guitar, you directly pluck a string
and the note sounds.
But how does a digital instrument go about playing a
note?
Acoustic guitar note
production
Pluck a string and the body
resonates the sound.
As shown in the illustration above, in an electronic
instrument, the sampled note (previously recorded note)
stored in the tone generator section (electronic circuit) is
played based on information received from the keyboard,
and output through the speakers.
