Problems Related to the USB Driver (Windows)
Exclusive messages are not
received
Is the instrument set to receive Exclusive messages? Set the Rx Sys-Ex parameter to ON (p. 76).
Does the Device ID number of the transmitting device
match the Device ID number of the V-Synth?
Check the Device ID parameter setting (p. 75).
Noise is heard while sampling During sampling, the output frequency of the digital
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.
This is not a malfunction.
Can’t edit or encode a wave Could you have selected a preset wave? The V-Synth’s factory-loaded preset waves cannot be
edited or encoded. Select a sample that you’ve sampled
or imported.
Beep tone was turned off, but
it continues to sound the next
time power is turned on
The Power-up Mode is set to “Default.” Change it to “Last Set” and save the System settings (p.
74).
Problem Cause Action
When I start (or restart) my
computer with the V-Synth
connected via USB, it freezes
at the startup screen and fails
to work
It has been found that on some computers, starting (or
restarting) the computer while the V-Synth is powered
up and USB is connected will cause the computer to
freeze at the startup screen and fail to work.
Switch off the V-Synth and then restart your computer.
When I turned off the power of
the V-Synth, an error oc-
curred in Windows
When using Windows Me, powering down the V-
Synth without unmounting the drive may cause an er-
ror to occur in Windows.
You must cancel the USB connection (p. 92) before you
turn off the power of the V-Synth.
When I attempt to exit Win-
dows while leaving the V-
Synth powered up, the com-
puter does not turn off
On some Windows computers, it has been reported
that the computer cannot be powered down if you exit
Windows when the V-Synth is still powered up (with-
out unmounting the drive). (The shutdown process
halts before the computer’s power is switched off.)
You must cancel the USB connection (p. 92) before you
turn off the power of the V-Synth before you exit Win-
dows.
When I connect the V-Synth
via USB and wake up my com-
puter from Suspend, it stops
functioning
On some computers, waking up the computer from the
Suspend state while a powered-up V-Synth is connect-
ed via USB will cause the computer to freeze.
Before you Suspend your computer, power down the
V-Synth using the procedure described on p. 92.
V-Synth driver is not mounted
in Windows XP
If a network drive is mounted in Windows XP, that
drive number may conflict with the V-Synth drive,
causing the V-Synth drive to not be recognized.
Change the assignment of the network drive.
“Find new hardware wizard”
does not execute automati-
cally
The “Insert Disk” dialog box
does not appear
“Find new hardware wizard”
ends before the process is
completed
* It may take about 15 seconds
(or more) after the USB cable
is connected for the V-Synth
to be detected.
Is the USB cable connected correctly? Make sure that the V-Synth and your computer are cor-
rectly connected via a USB cable.
Is USB enabled on your computer? Refer to the operation manual for your computer, and
make sure that USB is enabled.
Does your computer meet the USB specifications? 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 has been incorrectly detected by
the computer. As described in “Deleting Incorrect De-
vice Information” (p. 147), delete the incorrect device
information, then re-install the driver.
“Found unknown device” ap-
pears even though you in-
stalled the driver
If your computer or USB hub has two or more USB con-
nectors, and you connect the V-Synth to a USB connec-
tor to which the V-Synth has never been connected
before, the “Unknown device” dialog box may appear
even on a computer onto which you have already in-
stalled the driver.
Refer to Readme file on the included CD-ROM, and in-
stall the driver once again. This is not a malfunction.
If the “Found unknown device” dialog box appears
even though the V-Synth is connected to the same USB
connector as before, it is possible that the computer has
detected the V-Synth incorrectly. As described in “De-
leting Incorrect Device Information” (p. 147), delete
the incorrect device information, then re-install the
driver.
