Troubleshooting

Cannot select the V-Synth GT device

If the computer entered a Sleep mode while the V-Synth GT was connected with its power turned on, it may not operate correctly. In this case, after resuming, exit all software that are using the V-Synth GT, and then turn on the power of the V-Synth GT once again.
 

Cannot playback or record

Could you have entered Sleep mode during playback or recording?
If you entered Sleep mode during playback or recording, it will no longer be possible to play back or record from the V-Synth GT. Exit all currently playing or recording software, and switch the power of the V-Synth GT off, then back on again.
 

Occasional disruptions in the sound or noises occur.

Try adjusting the audio buffer size for the software you're using.
First, try adjusting the audio buffer size for the software you're using.
If sound dropouts or noise still occur during playback or recording, try adjusting the "Audio Buffer Size" in the Driver Settings panel.
*For some software, it may not be possible to adjust the buffer size.
 
Could you have performed a Mac OS X software update while the device was still connected?
If you performed the Mac OS X software update with the device left connected, drop-outs may occur in the sound. If this occurs, please re-install the driver.
 
Is the V-Synth GT connected to a USB hub?
Try connecting the V-Synth GT directly to the USB connector of your computer itself.
 

Occasional disruptions in the sound or noises are in the recorded audio data.

If the recorded audio still contains sound dropouts or noise even after you've adjusted the audio buffer size as described in "Occasional disruptions in the sound or noises occur." (above), try increasing the "Recording Margin" in the Driver Settings panel.
*For some software, it may not be possible to adjust the buffer size.
