ENABLING THE MOTU AUDIO WDM DRIVER
Once you’ve made the preparations described so 
far in this chapter, you’re ready to run your audio 
software and enable the MOTU Audio WDM 
driver. Check the audio system or audio hardware 
configuration window in your software.
Enabling the MOTU Audio WDM driver in 
SONAR
To activate the MOTU Audio WDM driver in 
SONAR:
1 Choose Audio from the Options menu.
2 Click the Drivers tab.
3 Check the UltraLite-mk3 inputs and outputs 
that you wish to use and uncheck the ones you 
don’t as shown in Figure 8-3.

highlighting UltraLite-mk3 inputs and outputs.
Enabling the MOTU ASIO driver in SONAR
As an alternative to the UltraLite-mk3’s WDM 
driver, you can use the UltraLite-mk3’s ASIO 
driver. Note, however, that you can only use one 
audio interface at a time under ASIO. Go to the 
Advanced tab and choose ASIO from the Driver 
Mode menu:

There are a few other settings in SONAR that 
impact UltraLite-mk3 operation:
1 In the Audio Options window, click the General 
tab.
2 Choose any UltraLite-mk3 input and output for 
recording and playback timing as shown below in 
Figure 8-5. It doesn’t matter which ones.
