The XV-2020 exits Edit mode.
SAVING AND LOADING DATA
Save performance, patch and rhythm set setting in the user area of the main
unit of XV-2020 and system setting to the PC as SVD file with the attached XV
editor.
Saving user data
1.
Connect the XV-2020 and the PC using a USB cable.
The PC to be connected shall be installed with XV-2020 driver and XV editor.
2.
Turn on the main power of XV-2020 and start up the XV Editor.
3.
Select [File]->[Save SVD file] in the menu.
4.
Specify the saving place and file name and then select [OK].
fig.Sur
5.
Press [VALUE] once more to execute the factory reset.
To cancel the procedure, while holding down [VOLUME] and pressing
[VALUE].
If there is important data you’ve created that’s stored in memory, all such data
is discarded, and everything is returned to the factory defaults when a Factory
Reset is performed. If important data is stored in the unit, save it on an
external device.
You cannot carry out this procedure when “DEMO” is selected with the
[CATEGORY/BANK] knob.
SYSTEM SOFTWARE UPDATE PROCEDURE
The XV-2020 uses a Flash Memory for the program ROM.
The version may be updated by externally sending the MIDI data.
Whenever updating is performed, factory setting must be restored.
If the user memory is written with important data, save data before updating.
Loading user data
1.
Connect the XV-2020 and the PC using a USB cable.
The PC to be connected shall be installed with XV-2020 driver and XV editor.
2.
Turn on the main power of XV-2020 and start up the XV Editor.
3.
Select [File] -> [Load SVD file] in the menu.
4.
Specify the saving place and file name and then select [OK].
RESTORING THE FACTORY SETTINGS
When using the XV-2020 for the first time, start by returning the settings to
their factory defaults so that the XV-2020 operates as described in the
procedures in the owner’s manual.
This returns all settings stored in memory in the XV-2020 to the values they
had when the unit was shipped from the factory.
1.
While holding down [VOLUME], press [VALUE].
The indication in the display begins flashing, and the mode changes.
2.
Turn [CATEGORY/BANK] to choose PIANO (UTILITY).
3.
Rotate [VALUE] until “Fct” appears in the display.
fig.Fct
What is needed
• XV-2020 Update Disk (2HD:3 disks) (No.17041190)
• A sequencer that can play an SMF (a synthesizer with a sequencer such
as the FANTOM may be used)
• MIDI cable
Updating
1.
Connect MIDI OUT of the external sequencer to MIDI IN of the XV-2020
with the MIDI cable.
Set the sequencer to enable chain play of SMF.
2.
Turn on the power while pressing [VOLUME] and [VALUE] and
continue pressing until [mid] is displayed.
fig.mid
3.
Releasing will display [---] and enters data receive waiting status.
fig.---
4.
Press [VALUE]; “Sur” flashes in the display, and a confirmation screen
appears.

4.
After confirming the display shown in step 3., play all “.mid” files on the
XV-2020 UPDATE DISKS 1 to 3 from the external sequencer. “r...” is
displayed during MIDI data receiving.
Page 12

fig.rcv
5.
When updating is completed without an error, [Fin] is displayed, and 4
LEDs, [PATCH], [PERFORM], [RYTHM] and [GM] blink simultaneously.
fig.Fin
6.
Restart the power and confirm that the system has been properly
updated.
7.
Finally, restore factory setting. This completes the update.
* When you fail in update, start the updating from the beginning.

• Monitor speakers (MA-12, etc.) 2pcs
• Audio cables 2pcs
• Audio cables (RCA type) 2pcs
• MIDI cable 1pcs
• USB cable 1pcs
• Wave expansion board SRX series 2pcs
• PC on which operation of XV-2020 is confirmed.
Precautions for the test
• The user data may be deleted when entering the test mode .
Always back up your data. (Saving and loading user data reference)
• Some test items produce verification sound.
• Mount the wave expansion board prior to turning the unit’s power on.
Connect the headphone and the monitor speaker in advance.
3.
Release and then promptly press [VOLUME] again while the [PATCH]
LED is turned on.
4.
“tSt” will be displayed and automatically proceed to LED Test.
fig.tSt
Exiting the Test mode
Turn off the power. Turning on the power again returns to normal mode.
Do not turn off the power during restoration of factory setting.
Proceeding to the next test item
If no error occurs during the Memory, Expansion Board, USB and MIDI tests,
the system automatically proceeds to the next test item.
For Program Version, Encoder and Rotary Switch Tests, pressing [VALUE]
proceeds to the next test item.
For Sound Test, pressing [VOLUME] proceeds to the next test item.
Proceeding through test items
At LED Test, setting [CATEGORY] to PIANO enters individual test mode and
enables to proceed to each test item by rotating [CATEGORY].
