Roland V-Studio VS-20 用户手册

Troubleshooting

There are Interruptions, 
Dropouts, or Other 
Problems in the Sound 
During Playback

Could you have connected/
disconnected another USB device, 
such as a memory key?

Dropouts may occur during playback or recording if you connect/disconnect another 
USB device (such as a memory key), or switch a device’s power on/off at the same time 
that the V-STUDIO 20 is being used.

Are you using a hard disk that is 
connected via USB?

Data transfer using USB could get congested if you use the V-STUDIO 20 and a USB-
connected hard disk at the same time. As a result, the data transfer speed for the hard 
disk could be significantly reduced. As a storage location for the audio data that you 
record and play back, you should avoid using a hard disk that is connected via USB.

Did the dropout occur immediately 
after the system started up, or after 
it woke from sleep?

Dropouts during playback/recording sometimes occur immediately after the system 
has started up, or after it has woken from sleep. Wait for a while, then try the playback/
recording again.

Windows Update/ Microsoft 
Update

Use Microsoft Corporation’s Windows Update or Microsoft Update to update your 
system to the most recent state.

“Audio Buffer Size” in the setting 
dialog box

See Audio Driver Settings (p. 24)

I did not see any meters move in 
Guitar Tracks or hear any sound

The most common cause of this is if the playback device is not set correctly. 
In most cases, you can correct this by following these steps:

• On the Options menu, click Audio to open the Audio Options dialog.

• Make sure the driver mode is set to “ASIO”

• Make sure you have “VS-20” selected for both playback and recording 

devices.

If you do not see an option for VS-20, check the settings described in “Audio Driver 
Settings” (p. 24).

I can see meters moving in Guitar 
Tracks, but I don't hear anything

• Make sure the “Output Level” on the VS-20 Hardware is turned up

• Make sure the “DAW Output” on the VS-20 Hardware is also turned up

Audio starts to play, but I get a 
message that says DROPOUT or 
AUDIO STOPPED either in a dialog 
or across the bottom of the screen

A dropout is a symptom of audio hardware when it is unable to pass audio data fast 
enough. There are a few things that may alleviate this:

• Check the settings described in “About Mixing Latency” (p. 46)

• Ensure nothing else is trying to use the sound device at the same time. 

Guitar Tracks will perform best when there are no other software 
applications attempting to use the sound device, such as web 
browsers, video players, instant messaging clients and other sound 
applications.

Clicks or pops may occur in the 
sound if a LAN is operating

Try disabling the LAN in Device Manager. If this eliminates the clicks or pops, you may 
be able to solve the problem by updating your LAN driver or BIOS.

Could you have connected the VS-
20 to a USB hub?

Try connecting the VS-20 directly to a USB connector on your computer.

Playback Halts Midway, 
and Subsequent 
Playback is Not Possible

While you were using the 
V-STUDIO 20, could your computer 
have performed a task with a heavy 
processing load, such as accessing 
a DVD-ROM drive or the network?

If a heavy processing load occurs while the V-STUDIO 20 is being used, it may not work 
correctly. In this case, stop playback, and then start playback once again.

 

If you are still unable to play, close all software that was using the V-STUDIO 20, 
disconnect the USB cable from the V-STUDIO 20 hardware, and then reconnect it.
