Accessory CD-ROM Installation Guide
■Troubleshooting
● The driver cannot be installed.
• Is the USB cable connected correctly?
Check the USB cable connection.
Disconnect the USB cable, then connect it again.
• Is the USB function enabled on your computer?
When you connect the instrument to the computer for
the first time, if the "Add New Hardware Wizard" does
not appear, the USB function on the computer may be
disabled. Perform the following steps.
1
Select [Control Panel]* ➔ [System] ➔ [Hardware]
➔ [Device Manager] (for Windows XP/2000), or
select [Control Panel] ➔ [Device Manager] (for
Windows Vista).
* Classic View only in Windows XP.
2
Make sure that no "!" or "x" marks appear at "Uni-
versal serial bus controller" or "USB Root Hub." If
you see an "!" or "x" mark, the USB controller is
disabled.
• Is any unknown device registered?
If driver installation fails, the instrument will be marked
as an "Unknown device," and you will not be able to
install the driver. Delete the "Unknown device" by
following the steps below.
1
Select [Control Panel]* ➔ [System] ➔ [Hardware]
➔ [Device Manager] (for Windows XP/2000), or
select [Control Panel] ➔ [Device Manager] (for
Windows Vista).
* Classic View only in Windows XP.
2
Look for "Other devices" in the menu "View
devices by type."
3
If you find "Other devices," double-click it to
extend the tree to look for "Unknown device." If
one appears, select it and click the [Remove] but-
ton.
4
Remove the USB cable from the instrument, and
make the connection again.
5
Install the driver again. (See pages 101–102.)
● When controlling the instrument from
your computer via USB, the instrument
does not operate correctly or no sound
is heard.
• Did you install the driver (pages 101–102)?
• Is the USB cable connected correctly?
• Are the volume settings of the instrument, playback
device, and application program set to the appropri-
ate levels?
• Have you selected an appropriate port in the
sequence software?
• Are you using the latest USB-MIDI driver?
The latest driver can be downloaded from the web
site (page 101).
