Playback Halts Midway,
and Subsequent
Playback is Not Possible
While you were using the VS-700,
could your computer have
performed a task with a heavy
processing load, such as accessing
a CD-ROM drive or the network?
If a heavy processing load occurs while the VS-700 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 VS-700, disconnect
the USB cable from the VS-700, and then reconnect it.
Problems with Recording
Problem
Points to check
Action
Can’t record
Could a message be indicating
“Unable to open audio record
device”?
If Media Player or another application that has audio playback capability is running,
SONAR won’t be able to use the audio driver, and an error will appear when SONAR is
started. Close the audio playback application, and then start SONAR again.
Make sure that SONAR’s Sampling Rate (p. 60) matches the settings of the VS-700R’s
[SAMPLE RATE]
knob.
If an audio driver not being used by SONAR is installed, try either disabling that driver
or disconnecting the corresponding audio interface from your computer.
Try changing the Driver Mode (p. 26).
Make sure that the Sampling Rate of the audio used in your project, the Sampling Rate
of SONAR, and the setting of the VS-700R’s
[SAMPLE RATE]
knob all match.
Dropouts occur in the
recording
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 VS-700 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 VS-700 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.
