What is MIDI?
Put simply, MIDI is a data transfer standard that allows
easy and comprehensive control among electronic/digi-
tal music instruments and other devices. To get a better
idea of what MIDI does, let’s first consider acoustic
instruments, such as a grand piano and a classical gui-
tar. With the piano, you strike a key, and a hammer
inside hits some strings and plays a note. With the gui-
tar, you directly pluck a string and the note sounds.
But how does a digital instrument go about playing a
note?
As shown in the illustration above, in an electronic
instrument the sampling note (previously recorded
note) stored in the tone generator section (electronic
circuit) is played based on information received from
the keyboard.
Now, let’s examine what happens when we playback a
recording. When you play back a music CD (for exam-
ple, a solo piano recording), you’re hearing the actual
sound (vibration in air) of the acoustic instrument. This
is called audio data, to distinguish it from MIDI data.
In the above example, the actual acoustic sounds of the
pianist’s performance are captured in the recording as
audio data, and this is recorded to CD. When you play
back that CD on your audio system, you can hear the
actual piano performance. The piano itself is not neces-
sary, since the recording contains the actual sounds of
the piano, and your speakers reproduce them.
Copying files from a computer hard disk to a
USB storage device
Files contained on the hard disk of a computer can be
transferred to the instrument by first copying them to the
storage media, then connecting/inserting the media to the
instrument.
Not only files created on the instrument itself but also
Standard MIDI files and Style File-formatted Style files cre-
ated on other devices can be copied to SmartMedia card
or a USB storage device from the hard disk of the com-
puter. Once you’ve copied the data, insert the card into
the Card slot or connect the device to the [USB TO
DEVICE] terminal of the instrument, and play back the
data on the instrument.
