MIDI Functions
The information related to Voice changes is called “program change” in MIDI. Sending and receiving program change
messages can be enabled or disabled as desired on this instrument. For example, if the relevant transmit and receive
parameters are set to ON, Voice change information in this instrument can be transmitted to or received from a computer.
(However, the Voice as played from the keyboard is maintained and does not change.)
For information on program
change numbers for each of
the Voices of the instrument,
refer to page 4.
Default setting: ON
While holding down [DEMO/SONG] and [PIANO/VOICE], press the C
#
5 key. Pressing
the C
#
5 key repeatedly toggles between Local Control On and Off.
Information related to non-note expressive changes, such as the use of a sustain pedal, is called “control change” in
MIDI. Sending and receiving control change messages can be enabled or disabled as desired on this instrument. For
example, if the relevant transmit and receive parameters are set to ON, pedal performance information on this instrument
can be transmitted to or received from a computer. (However, the performance of pedals and other controls as played
from the instrument is maintained and does not change.)
For information on control
changes that can be used with
the instrument, refer to page 5.

While holding down [DEMO/SONG] and [PIANO/VOICE], press the D5 key. Pressing the
D5 key repeatedly toggles between Local Control On and Off.
Try this operation when playback of Songs loaded from the computer produces an unexpected or unnatural sound.
To set Song Playback Channels to “1+2”:
While holding down [DEMO/SONG] and [PIANO/VOICE] simultaneously, press the C7
key.
With this operation, the Song data of only channels 1 and 2 will be played back. When

parts are assigned to the channels 1 and 2, this operation results in the proper or
expected sound.
To set Song Playback Channels to “ALL”:
While holding down [DEMO/SONG] and the [PIANO/VOICE] simultaneously, press the
B6 key.
