MIDI
General MIDI
As we have already seen, MIDI makes it possible to exchange
musical data between devices produced by different
manufacturers. This musical data does not consist of the notes
themselves, but rather information on whether a keyboard
key is pressed or released, and the tone number.
If tone number 1 on a keyboard produced by Company A is
PIANO while tone number 1 on a Company B's keyboard is
BASS, for example, sending data from Company A's keyboard
to Company B's keyboard produces a result entirely different
from the original. If a computer, sequencer or other device
with auto accompaniment capabilities is used to produce
music data for the Company A keyboard which has 16 parts
(16 channels) and then that data is sent to the Company B
keyboard which can receive only 10 parts (10 channels), the
parts that cannot be played will not be heard.
The standard for the tone numbering sequence, the number
of pads, and other general factors that determine the sound
source configuration, which was arrived at by mutual
consultations by manufacturers, is called General MIDI.
The General MIDI standard defines the tone numbering
sequence, the drum sound numbering sequence, the number
of MIDI channels that can be used, and other general factors
that determine the sound source configuration. Because of
this, musical data produced on a General MIDI sound source
can be played back using similar tones and identical nuances
as the original, even when played on another manufacturers
sound source.
This keyboard conforms with General MIDI standards, so it
can be connected to a computer or other device and used to
play back General MIDI data that has been purchased,
downloaded from the Internet, or obtained from any other
source.
Changing MIDI Settings
You can use this keyboard in combination with an external
sequencer, synthesizer, or other MIDI device to play along
with commercially available General MIDI software. This
section tells you how to make the MIDI settings required
when connecting to an external device.
SETTING Button
Each press of the SETTING button cycles through a total of
11 setting screens: the touch response screen, the
accompaniment volume screen, the tuning screen, and 8 MIDI
setting screens. If you accidentally pass the screen you want
to use, keep pressing the SETTING button until the screen
appears again. Also note that leaving a setting screen is
automatically cleared from the display if you do not perform
any operation for about five seconds.
GM MODE (Default: Off)
