MAKING SETTINGS IN MOTU AUDIO SETUP
Before you run your audio software, launch MOTU
Audio Setup to configure your 8pre hardware.
MOTU Audio Setup 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 Audio Setup” (page 23).
Figure 8-1: MOTU Audio Setup gives you access to all of the settings in
the 8pre hardware, including the clock source, sample rate and
optical I/O enable/disable.
For complete details about the 8pre settings, see
chapter 5, “MOTU Audio Setup” (page 23). The
following sections provide a brief explanation of
each 8pre setting for use with SONAR.
Sample rate
Choose the desired overall sample rate for the 8pre
system and SONAR. Newly recorded audio in
SONAR will have this sample rate.
Clock Source
This setting is very important because it
determines which audio clock the 8pre will follow.
If you do not have any digital audio connections to
your 8pre (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 have digital audio devices connected to the
8pre, or if you are not sure about the clock source of
your setup, be sure to read “Syncing optical
devices” on page 22 and “Clock Source” on
page 24.
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
8pre hardware and SONAR. For example, you
might have MIDI instruments, samplers,
microphones, and so on connected to the analog
inputs of the 8pre. If so, you will often be mixing
their live input with audio material recorded in
SONAR. See chapter 10, “Reducing Monitoring
Latency” (page 45) for complete details.
Optical input and output
To make a 8pre optical input or output available in
SONAR, choose
ADAT from the optical input
and/or output menu. If you won’t be using the
optical connectors, turn them off.
Phones
This 8pre setting lets you choose what you’ll hear
from the headphone jack. For example, if you
choose
Main Outs 1-2 , the headphones will
duplicate the main outs. Or you can choose any
other output pair. If you choose
Phones 1-2 , this
setting makes the headphone jack serve as its own
independent output pair. As a result, you’ll see
Phones 1-2 as an additional audio destination in
SONAR’s audio output menus.
