In particular, since DAW (Digital Audio

engines that are different from OS settings, 
confirm the DAW driver settings first after 
installing the driver for this unit. Check the 
manuals for the software that you are using 
for details about how to make these settings.
For the bundled Cubase LE 5 software, see 
the manual on the included Cubase LE 5 
DVD-ROM.
The sound breaks up or there is
ª
noise.
The processing load on the computer can 
cause sound to break up and noise to occur.
Some ways to reduce the load on a computer 
are introduced below. 
1) If a wireless LAN, antivirus software 
or other software are running in the 
background, they regularly use the 
computer’s CPU, and this burden can 
cause sound to break up and noise to 
occur.
Stop wireless LAN transmission, antivirus 
software and other software running in 
the background when using this unit.
2) Try increasing the buffer size (latency)
setting in the audio application that you 
are using and/or in the control panel for 
this unit.
NOTE
Consult the maker of your audio application 
for methods to reduce its burden on your 
computer.
3) Change the settings of your computer 
so that they are optimal for audio 
processing.
