Customizing with Function Parameters
F7. 5
Program change on/off status
MIDI Program Change messages can be sent from one
MIDI device to another in order to change its Voice. In
other words, your digital piano could use a Program
Change message to change the voice being used on a con-
nected device. (When a new Voice is selected using the con-
trol panel, the corresponding Program Change Number
would be sent.) Meanwhile, upon the receipt of a Program
Change message from a connected MIDI device, your digi-
tal piano can change the Voice being used to play the
received MIDI data (but not the Voice played via the key-
board). This parameter should therefore be set to "ON" if
you wish to send and receive MIDI Program Change mes-
sages, thereby linking Voices on the digital piano with those
on connected devices. If, however, you do not want to link
Voices in this way, you should set this parameter to "OFF".
NOTE
• Refer to the MIDI Reference pdf manual for details of the MIDI Program Change
Numbers associated with the instrument's Voices.
• Available settings: ON and OFF
• Default setting: ON
F7. 6
Control change on/off status
MIDI devices use Control Change messages in order to
inform each other of damper pedal operations, volume
changes, and other actions associated with the expressive-
ness of a performance. In other words, your digital piano
could send Control Change messages via MIDI to affect the
sound of a performance being played on a connected
device. (Whenever you operate the instrument's damper
pedal, it would send the corresponding Control Change
messages.) Meanwhile, upon the receipt of a Control
Change message from a connected MIDI device, your digi-
tal piano can change the sound of the MIDI performance
being played (but not the sound being played using the key-
board). This parameter can be used to turn on and off the
exchange of MIDI Control Change messages as appropri-
ate.
NOTE
• Refer to the MIDI Reference pdf manual for details of the Control Change data
supported by your digital piano.
• Available settings: ON and OFF
• Default setting: ON
F7. 7
Send initial setup
This parameter can be used as described below to send ini-
tial setup data—that is, the current state of control panel
settings—to a connected sequencer or other device. For
example, you could send this data before recording a per-
formance on the sequencer or device, thereby saving the
digital piano's current settings at the beginning of the
recording. In addition, you could also send this data to the
tone generator of another instrument in order to configure it
in the same way as the digital piano's.
1
Set the control panel as required.
2
Connect the sequencer and configure it to receive
and record the initial setup data.

parameter .
4
Press the [+/YES] button to send the data.
The message "End" will be shown when the data has
been sent.
Initial setup data contains the following settings.
• Voice(s)
• Reverb type and depth
• Effect type and depth
• Split point
• Tuning system (F2. 1 )
• Dual balance (F3. 1 )
• Relative Voice detune (F3. 2 )
• Dual balance (F4. 2 )
• Certain pedal and special sound settings (F5. 2 to F5. 6 )
F8. Backup and other settings
Using your digital piano's Backup function, you can save
Voice selections, reverb type, and many other settings to
ensure that they are retained when you turn off the instru-
ment. If turned on, this function will restore your previous
settings automatically when you turn on your digital piano.
If turned off, however, the settings stored in the instru-
ment's internal memory will be lost; accordingly, the corre-
sponding defaults (page 48) will be restored when you next
turn it on. That said, performance data stored in the internal
memory, the character code setting, and the on/off status of
the Backup function will always be automatically retained.
As described below, the Backup function can be turned on
or off individually for different types of settings (i.e., Voice,
MIDI, tuning, and miscellaneous). The corresponding
Function-parameter settings will also be retained.
NOTICE
• It can take several seconds to save the instrument's set-
tings. For this reason, any setting changed immediately
before the digital piano is turned off may not be retained.
