Figure 7-1: MOTU Audio Console gives you access to all of the settings
in the Audio Express hardware, including the clock source and
sample rate.
For complete details about the Audio Express
settings, see chapter 5, “MOTU Audio Console”
(page 27). The following sections provide a brief
explanation of each Audio Express setting for use
with Cubase.
Sample rate
Choose the desired overall sample rate for the
Audio Express system and Cubase. Newly recorded
audio in Cubase will have this sample rate.
Clock Source
This setting is very important because it
determines which audio clock the Audio Express
will follow.
If you do not have any digital audio connections to
your Audio Express (you are using the analog
inputs and outputs only), and you will not be
slaving Cubase to external SMPTE time code,
choose Internal.
If you have a S/PDIF digital audio device
connected to the Audio Express, see “Connect and
sync S/PDIF devices” on page 22.
If you are slaving the Audio Express and Cubase to
SMPTE time code via the Audio Express itself,
choose SMPTE and follow the directions in
“Resolving Cubase or Nuendo to SMPTE time
code” on page 77.
☛ If you are using an ASIO host application
other than Cubase or Nuendo, it must support the
ASIO 2.0 sample-accurate positioning protocol in
order to support the Audio Express’s direct SMPTE
sync (and sample-accurate sync) feature.
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
Audio Express hardware and Cubase. For example,
you might have MIDI instruments, samplers,
microphones, and so on connected to the analog
inputs of the Audio Express. If so, you will often be
mixing their live input with audio material
recorded in Cubase. See chapter 9, “Reducing
Monitoring Latency” (page 45) for complete
details.
Phones
This Audio Express setting lets you choose what
you’ll hear from the headphone jack. For example,
if you choose Main Out 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
Cubase’s audio output menus.
