Getting Connected and Installing Drivers (Windows)
Installing the special driver
Windows XP/2000 users
The 
CD-ROM
 contains two types of driver for Windows XP/2000.
Normally, you should use the 
WDM driver
.
WDM driver
You should use this driver if you have specified WDM driver mode for SONAR or 
a similar application. This will provide the highest-quality audio performance.
* It is not possible to use 24-bit audio with applications that do not support a WDM driver 
mode, such as Cool Edit or Media Player.
Switching between Advanced mode and Standard driver mode
If you first install both the special driver and the standard driver, you will be able 
to switch between Advance and Standard driver modes by operating the UA-20's 
ADVANCE (mode select) switch
.
* In order for the setting of the 
ADVANCE (mode select) switch
 to take effect, you must 
exit all sequencer software and other applications that use the UA-20, and re-connect the 
UA-20.
The installation procedure will differ depending on your system.
Please proceed to one of the following sections, depending on the system you use.

• Windows Me/98 users.....................................(p. 29)
MME driver
This driver allows you to use 24-bit audio even from applications that do not have 
a WDM driver mode, such as Cool Edit. It is not possible to use the MME driver 
from WDM driver mode of an application such as SONAR.
* It is not possible to install both the WDM driver and the MME driver. You must select 
one beforehand, and install only that driver. If after installing one of these drivers you 
decide to change drivers, you must first delete the already-installed driver and then 
install the new driver. (
 
* The WDM driver and the MME driver can be installed using the same procedure.
