recognize the unit.
If some trouble is causing installation to fail, or if the computer
does not recognize the unit even though installation completes,
check the following.
1. Change the USB port
Since the unit might not properly function with some
USB ports, try connecting to a different USB port that is
built into the computer, and reinstall the driver.
NOTE
• Try again after disconnecting other USB devices. (Keyboards
and mice can be left connected.)
• Do not use a USB hub. Always connect the unit directly to a
USB port on the computer (built-in).
2. Stop software that is running in the background
Since antivirus software and other software running in
the background can interfere with installation, stop them
before beginning installation. See "Installing the driver
and Settings Panel" on page 6 in this manual for how
to install and uninstall the driver and Settings Panel.

Depending on the application that you are using, you might
need to make additional device settings.

with settings that are different from the OS settings, so first
confirm the DAW settings after installing the driver and

Sound breaks up or there is noise.
8
The processing load on the computer causes sound to break up
and noise to occur.
Here are some methods to reduce the load on the computer.
1. A wireless LAN and software running in the background,
including antivirus software, regularly put processing
loads on the computer, which can cause sound to break up
and other noise. Stop wireless LAN transmission, antivirus
software and other software running in the background
when using this unit.
2. Set the buffer size (latency) in the audio application that you
are using or in this unit's Settings Panel to a larger value.
(Windows only)
NOTE
Consult the maker of the audio application that you are
using for methods to reduce its load on your computer.
3. Change the settings of your computer so that they are
optimal for audio processing.
