NOTE ON/OFF

This message sends data when a key is pressed (NOTE ON)
or released (NOTE OFF).
A NOTE ON/OFF message includes a note number (to
indicate note whose key is being pressed or released) and
velocity (velocity=100 when the volume value of this unit is
9 to 2, and velocity=75 when the volume value is 1 or 0).
NOTE ON velocity is always used to determine the relative
volume of the note. This keyboard does not receive NOTE
OFF velocity data.
Whenever you press or release a key on this keyboard, the
corresponding NOTE ON or NOTE OFF message is sent by
constant velocity from the MIDI OUT terminal.

PROGRAM CHANGE

This is the tone selection message. PROGRAM CHANGE can
contain tone data within the range of 0 to 127.
A PROGRAM CHANGE message (0 to 99) is sent out through
this keyboard’s MIDI OUT terminal whenever you manually
change its tone number. Receipt of a PROGRAM CHANGE
message from an external machine changes the tone setting
of this keyboard.
This keyboard can send tone data within the range of 00 to
99 and receive tone data within the range of 0 to 127

*

. Each

of the 128 General MIDI tones is automatically assigned to
one of the keyboard’s 100 built-in tones as shown on page A-
1. Select this setting when you want to listen to General MIDI
data from a computer or other external equipment.

*

When GM mapping is turned on (page E-31). When turned
off, tone data is received in the range of 0 to 99.

sounds percussion sounds produced by this keyboard.

PITCH BEND

This message carries pitch bend information for smoothly
sliding the pitch upwards or downwards during keyboard
play. This keyboard does not send pitch bend data, but it can
receive such data.

LOCAL CONTROL (Default: on) /GM mapping
(Default: off)

This setting determines whether or not the keyboard and
sound source of this keyboard are connected internally. When
recording to a computer or other external device connected
to this keyboard’s MIDI IN/OUT terminal, it helps if you
turn LOCAL CONTROL off.

on:

Anything played on the keyboard is sounded by the
internal sound source and simultaneously output as a
MIDI message from the MIDI OUT terminal.

Anything played on the keyboard is output as a MIDI
message from the MIDI OUT terminal, without being
sounded by the internal sound source. Turn LOCAL
CONTROL off whenever you are using the MIDI THRU
function of a computer or other external device. Also
note that no sound is produced by the keyboard if
LOCAL CONTROL is turned off and no external device
is connected.

NOTE

• When you are using this keyboard in a stand-alone

configuration, keyboard keys do not light while local control is
turned off.
