4.  Working with the FCA202
4.1  Device drivers and latency
A device driver is an interface that ensures communication 
between the software (audio application) and the hardware 
(the FCA202). In recent years, the PC platform has witnessed the 
establishment of several different driver models for sound cards. 
Some of these drivers cannot be used for simultaneous recording 
and playback or for working with software plug-ins, since they do 
not support the full range of functions provided by professional 
sound cards and cause a long time delay (latency). 
The FCA202 software provides a number of driver models 
for Windows platforms and for professional recording. 
With standard Windows-applications, you don’t need to worry 
about which driver is currently being used by the operating 
system. You only need to select the correct playback device via 
the Windows “Control Panel”. 
However, as soon as you start to produce or record 
computer-based music and work with special audio software 
such as Cubase, Live, Logic, Tracktion, or others, you should 
make sure that you selected an ASIO driver. This driver model 
supports the full range of functions offered by your hardware 
and gives you the best performance. 
You will normally find the selection of a driver model for the 
FCA202 hardware in an audio setup menu or in the standard 
default settings of the software you are using. If necessary, 
check the documentation for your software.
If you work with the program Sonar from Cakewalk, you can 
also use the WDM KS driver, since this achieves comparable 
latencies to the ASIO driver. In case of doubt, check whether 
the ASIO or the WDM KS driver gives better results with your 
Sonar system.
Things are much simpler with the Mac platform. 
With OS X, there is only one driver model, the CoreAudio driver. 
Thus there´s no need to worry about which driver to select.
◊  In PC systems, the latency very much depends on the 
driver used. For recording, always select an ASIO driver 
and use the CONTROL PANEL to set up a lower latency 
(less than 16 ms). The smaller the value, the better. 
If audio dropouts occur, try increasing the latency 
in stages.
