This process chooses the optimum settings for the 
UltraLite-mk3 hardware.
WORKING WITH ULTRALITE-MK3 INPUTS 
AND OUTPUTS
Once you’ve enabled the UltraLite-mk3 inputs and 
output, UltraLite-mk3 audio inputs and outputs 
will appear in your host software’s input/output 
menus, and you can set them up and use them as 
any standard audio input and output.
Return Assign
In SONAR, you’ll see an UltraLite-mk3 input pair 
called Return 1-2. This is a stereo feed from the 
UltraLite-mk3 that matches the output of one of its 
output pairs. Use the Return Assign menu in 
MOTU Audio Console to choose which output 
pair you would like to hear on this return. This can 
be used, for example, to record back a final stereo 
mix that includes effects processing from the 
UltraLite-mk3 DSP (such as the Leveler) for 
reference and archiving purposes.
☛ Warning: the Return inputs can cause 
feedback loops! DO NOT assign this input to a 
track that shares the same UltraLite-mk3 output 
pair as the returns.
Reverb return
The UltraLite-mk3 also supplies a return to your 
host software that carries the output of its reverb 
processor. This return can be used for any purpose 
you wish.
The “Phones 1-2” output
If you’ve chosen to treat the UltraLite-mk3 
headphones as an independent output, you’ll see 
Phones 1-2 as an UltraLite-mk3 output destination. 
Audio tracks assigned to this output pair will be 
heard on the headphone jack only. For further 
explanation, see “Phones Assign” on page 32.
CHANGING ULTRALITE-MK3 SETTINGS
You can change the UltraLite-mk3 settings at any 
time by accessing MOTU Audio Console.
REDUCING DELAY WHEN MONITORING 
LIVE INPUTS
If you have live audio inputs connected to the 
UltraLite-mk3, such as MIDI synthesizers, 
samplers, microphones or other live instruments, 
you might hear a slight delay when their audio is 
being monitored through your UltraLite-mk3 
hardware and your host audio program. There are 
several ways to reduce — and eliminate — this 
audible monitoring delay. For details, see chapter 9, 
“Reducing Monitoring Latency” (page 55).
PROCESSING LIVE INPUTS WITH HOST-
BASED VST PLUG-INS
If you patch a live input (such as MIDI synthesizer) 
through a plug-in effect in SONAR, you might hear 
a slight delay. There are several ways to reduce this 
delay. For details, see chapter 9, “Reducing 
Monitoring Latency” (page 55).
WORKING WITH CUEMIX FX MIXING AND 
EFFECTS
The UltraLite-mk3 provides powerful external 
mixing, EQ, compression and reverb, which you 
can operate hand-in-hand with your host 
software’s complete mixing environment. For 
example, the UltraLite-mk3 can serve as a monitor 
mixer routing channels to musicians, or it can 
serve as an integrated extension of your SONAR 
mixing environment. If you program an 
UltraLite-mk3 mixing and processing 
configuration that goes hand in hand with your 
SONAR project, be sure to use the file save features 
in CueMix FX to save the UltraLite-mk3 settings as 
a file in your SONAR project folder for instant 
recall of all settings. See chapter 10, “CueMix FX” 
(page 61) for complete details.
MIDI I/O VIA THE ULTRALITE-MK3 MIDI 
PORTS
Once you’ve run the UltraLite-mk3 software 
installer as explained in “Installing the 
UltraLite-mk3 software” on page 15, the 
UltraLite-mk3 MIDI ports will appear as a MIDI
