Problems with Playback

Can’t open song data

Is there sufficient free space on the 
hard disk?

When opening a song data, make sure that there is sufficient space on the hard disk (at 
least as much as the size of the song data)

A message indicates “Not a 
Cakewalk Format File.”

It may be that the file has been damaged. You may be able to recover some of the data 
by opening the file in Safe Mode. For details, refer to the Guitar Tracks 4’s online Help 
section File Recovery Mode.

No sound at all

Is your sound reproduction 
equipment (speakers, 
headphones) connected correctly?

Connect your audio reproduction equipment. 

 

Is the power switch turned on?

Make sure that your sound reproduction system and the V-STUDIO 20 hardware is 
powered up.

Are the volume knobs raised?

Make sure that the volume knobs of your sound reproduction system, the V-STUDIO 
20’s 

 knob, 

 knob, and 

 knob 

are raised.

Is the VS-20’s driver correctly 
installed?

Make sure that the VS-20’s driver is installed correctly.

Could you have disconnected the 
USB cable while Guitar Tracks 4 was 
running?

If you perform such actions while Guitar Tracks 4 is running, communication between 
Guitar Tracks 4 and the V-STUDIO 20 hardware will be interrupted, and Guitar Tracks 4 
may stop responding. 

 

Check the connection to the V-STUDIO 20 hardware, restart your computer, and restart 
Guitar Tracks 4.

Could your computer have entered 
Suspend or sleep mode while 
Guitar Tracks 4 was running?

Could a message be indicating 
“Unable to Open Audio Playback 
Device”?

If Media Player or another application that has audio playback capability is running, 
Guitar Tracks 4 won’t be able to use the audio driver. Close the audio playback 
application, and then start Guitar Tracks 4 again.
