Cause
Is the instrument set to transmit MIDI messages?
Does the MIDI transmit channel for the V-Synth XT
match the MIDI receive channel for the connected
MIDI device?
Is the instrument set to receive Exclusive messages?
Does the Device ID number of the transmitting device
match the Device ID number of the V-Synth XT?
audio interface is fixed at 44.1 kHz, regardless of the
System mode setting. Noise may be heard from con-
nected devices at this time.
Could you have selected a preset wave?
The Power-up Mode is set to "Default."
Cause
It has been found that on some computers, starting (or
restarting) the computer while the V-Synth XT is pow-
ered up and USB is connected will cause the computer
to freeze at the startup screen and fail to work.
When using Windows Me, powering down the V-
Synth XT without unmounting the drive may cause an
error to occur in Windows.
On some Windows computers, it has been reported
that the computer cannot be powered down if you exit
Windows when the V-Synth XT is still powered up
(without unmounting the drive). (The shutdown pro-
cess halts before the computer's power is switched off.)
On some computers, waking up the computer from the
Suspend state while a powered-up V-Synth XT is con-
nected via USB will cause the computer to freeze.
If a network drive is mounted in Windows XP, that
drive number may conflict with the V-Synth XT drive,
causing the V-Synth XT drive to not be recognized.
Is the USB cable connected correctly?
Is USB enabled on your computer?
Does your computer meet the USB specifications?
Action
Check the Patch Tx Ch parameter setting (p. 127).
Check the Patch Tx Ch parameter setting (p. 127).
Set the Rx Sys-Ex parameter to ON (p. 125).
Check the Device ID parameter setting (p. 125).
This is not a malfunction.
The V-Synth XT's factory-loaded preset waves cannot
be edited or encoded. Select a sample that you've sam-
pled or imported.
Change it to "Last Set" and save the System settings (p.
123).
Action
Switch off the V-Synth XT and then restart your com-
puter.
You must cancel the USB connection (p. 140) before
you turn off the power of the V-Synth XT.
You must cancel the USB connection (p. 140) before
you turn off the power of the V-Synth XT before you
exit Windows.
Before you Suspend your computer, power down the
V-Synth XT using the procedure described on p. 140.
Change the assignment of the network drive.
Make sure that the V-Synth XT and your computer are
correctly connected via a USB cable.
Refer to the operation manual for your computer, and
make sure that USB is enabled.
If you are using a computer that does not fulfill the
electrical requirements of the USB specifications, oper-
ation may be unstable. In this case, you may be able to
solve the problem by connecting a USB hub.
If the above actions do not solve the problem, it is pos-
sible that the V-Synth XT has been incorrectly detected
by the computer. As described in "Deleting Incorrect
Device Information" (p. 195), delete the incorrect de-
vice information, then re-install the driver.
