MAKING SETTINGS IN THE MOTU FIREWIRE
AUDIO CONSOLE
Before you run your audio software, launch the
MOTU FireWire Audio Console to configure your
Traveler ha rdw are . T h e MOTU FireWire Audio
Console lets you choose the audio clock source,
and it lets you enable the optical input and output,
if needed. For details, see chapter 5, “MOTU
FireWire Audio Console” (page 39).
Figure 8-1: The MOTU FireWire Audio Console gives you access to all
of the settings in the Traveler hardware, including the clock source,
sample rate and optical I/O enable/disable.
For complete details about the Traveler settings, see
chapter 5, “MOTU FireWire Audio Console”
(page 39). The following sections provide a brief
explanation of each Traveler setting for use with
Sonar.
Sample rate
Choose the desired overall sample rate for the
Traveler sys tem and Sonar. Newly recorded audio
in Sonar will have this sample rate.
Before running the Traveler at the 4x sample rates,
see “Operation at 4x sample rates (176.4 or
192kHz)” on page 40.
Clock Source
This setting is very important because it
determines which audio clock the Traveler will
follow.
If you do not have any digital audio connections to
your Traveler (you are using the analog inputs and
outputs only), and you will not be slaving Sonar to
external SMPTE time code, choose Internal.
If you are slaving the Traveler to the ADAT sync
Input connector, choose ADAT 9-pin.
If you have digital audio devices connected to the
Traveler, or if you are not sure about the clock
source of your setup, be sure to read “Making sync
connections” on page 27 and “Clock Source” on
page 40.
Samples Per Buffer
The Samples Per Buffer setting can be used to
reduce the delay — or monitoring latency — that
you hear when live audio is patched through your
Traveler ha rdw are a n d S onar. For example, you
might have MIDI instruments, samplers,
microphones, and so on connected to the analog
inputs of the Traveler. If so, you will often be
mixing their live input with audio material
