Figure 10-3: In Cubase or Nuendo, choose Devices menu> Device
Setup and click VST Audio System to access the window above and
the Audio Buffer Size setting.
Figure 10-4: In Logic Pro or Logic Express, go to the Audio Driver
preferences to access the Buffer Size option shown above.
Figure 10-5: This diagram shows the signal flow when using CueMix FX no-latency monitoring. Notice that this method does not process the
live input with plug-ins in your audio software. Instead, you can apply Traveler-mk3 effects, such as the reverb, EQ and/or compression.

Lower latency versus higher CPU overhead
The buffer setting has a large impact on the
following things:
Patch thru latency
■
The load on your computer's CPU
■
Possible distortion at the smallest settings
■
How responsive the transport controls are in
■
AudioDesk, Digital Performer or other audio
software
The buffer setting presents you with a trade-off
between the processing power of your computer
and the delay of live audio as it is being patched
through your software. If you reduce the size, you
reduce patch thru latency, but significantly increase
the overall processing load on your computer,
leaving less CPU bandwidth for things like real-
time effects processing. On the other hand, if you
increase the buffer size, you reduce the load on
your computer, freeing up bandwidth for effects,
mixing and other real-time operations.
3. Mic signal is mixed with the
main outs, and you can control
the volume (relative to the rest
of the mix) with the mic's fader
in CueMix FX.
1. Live input (from mic, guitar, etc.)
enters the MOTU interface.
2. CueMix FX immediately patches the live
mic signal directly to the main outs (or
other output), completely bypassing the
computer. This signal could be dry, or with
Traveler-mk3 effects processing, such as EQ,
compression or Classic Reverb.
