A
Troubleshooting
Some or all of my MOTU interface inputs and
outputs are not available in my host audio
software.
Make sure that the inputs and outputs are enabled
in the Device tab (“Device tab” on page 12) and
routed to and from the computer in the Routing
tab (“Routing tab” on page 15). For details, see
“Making inputs and outputs available to your host
software” on page 50.
I have absolutely no audio input or output
happening to or from my interface. Why?
Make sure that the unit has a stable sample rate (the
sample rate will flash if the clock hasn’t settled yet).
Try setting the unit’s clock source to
Internal
if you
can’t sync to any external clock sources. Check that
audio is working with Internal sync, and if so, then
work on establishing a stable external clock.
I can't hear computer audio output through my
MOTU interface.
In the Sound panel of System Preferences, the
UltraLite-mk4 should be selected as the output
device. Almost all applications will use just the first
two output channels, so make sure that
From
Computer 1 and From Computer 2 are routed to the
physical outputs that you are listening to in the
Routing tab (e.g. Phones 1-2 or Analog 1-2).
How do I monitor live inputs?
Please refer to the documentation for the audio
application that you are using. If your application
does not support input monitoring, you will need
to use the mixer in the UltraLite-mk4. Please see
“Monitoring through the UltraLite-mk4” on
page 46.
How do I control monitoring latency?
See “Reducing monitoring latency” on page 46.
The Routing tab (page 15) doesn’t display some of
the inputs or outputs on my interface.
The Routing tab only displays input and output
banks that are enabled in the Device tab (page 12),
so be sure any banks you wish to work with are
enabled there. However, to conserve DSP resources
and help consolidate screen-space in the other
tabs, it is efficient practice to disable unused input
or output banks (optical banks, for example, when
only working with analog banks, or all output
banks when only working with Phones).
I'm getting a “Could not enable this effect because
DSP is overloaded” error. What should I do?
Disable other effects or reduce the number of mixer
inputs to conserve DSP resources. If there are audio
input and output banks on your interface that you
are not using (such as the optical banks), disable
them in the Device tab (page 12).
I accidentally deleted my factory presets. How do I
restore them?
In the Device tab (page 12), click the Restore
Factory Presets button to restore all factory presets.
How do I factory reset my device?
Push the SELECT knob/button to enter the main
menu. Navigate to
Settings > Factory Default
and
push the SELECT knob/button twice to reset.
Clicks and pops due to hard drive problems...
If you have checked your clock settings and you are
still getting clicks and pops in your audio, you may
have a drive related problem. Set your Clock
Source to
Internal
and try recording just using the
analog inputs and outputs on the UltraLite-mk4. If
you encounter the same artifacts you may want try
using another drive in your computer. Clicks and
pops can also occur when the drive is severely
fragmented or there are other drive-related issues.
