The 'Mix1' input pair
The Mix1 input pair delivers the output of CueMix
DSP "MIX1" (the first mix bus of the four on-
board no-latency monitor mixes in the Traveler)
back to your computer. This input serves, for
example, as a convenient way for you to record the
Traveler's MIX1 monitor mix back into your host
audio software (for reference and archiving
purposes). Further, if you are sending audio from
your host audio software to the same output pair as
MIX1, you can choose to either include or exclude
the audio from the computer in the stream being
sent back to the computer. For details on how to do
this, see "Mix1 Return Includes Computer" on
page 84.
The Mix1 1-2 input is not available at the 4x sample
rates (176.4 or 192kHz).
☛
Warning: the Mix1 input can cause feedback
loops! DO NOT assign this input to a track that
shares the same Traveler output pair as MIX1.
Phones 1-2
If you've chosen to treat the Traveler headphones as
an independent output, they appear in your host
software as an independent output pair. Audio
tracks assigned to this output pair will be heard on
the headphone jack only. For further explanation,
see "Phones" on page 48.
NUMBER OF CHANNELS
If your host audio software requires that you
specify the number of audio voices or channels you
will be using, be sure to choose enough channels to
cover the 20 inputs and 22 outputs provided by
your Traveler — although the number of channels
may depend on how your Traveler is configured:
10 channels for analog I/O (including the
■
headphone out)
2 channels for RCA S/PDIF
■
2 channels for AES/EBU
■
72
Zero, 2 or 8 channels for optical, depending on
■
whether you have optical turned off, or set to
TOSLink or ADAT optical
For example, if you are using analog only, you only
need 10 channels. If you are using analog and RCA
S/PDIF, you need 12 channels.
As another example, if you are using analog, RCA
S/PDIF, AES/EBU and ADAT optical, you need 22
channels (the maximum number of simultaneous
output channels provided by the Traveler).
PROCESSING LIVE INPUTS WITH PLUG-INS
If you patch a live input (such as MIDI synthesizer)
through a plug-in effect in your host software, you
might hear a slight delay. There are several ways to
reduce this delay. For details, see chapter 10,
"Reducing Monitoring Latency" (page 73).
SYNCHRONIZATION
As of Version 10.3.6, Mac OS X does not allow
third-party applications to take advantage of the
Traveler's sample-accurate sync features or on-
board SMPTE sync features. Refer to
www.motu.com for further developments.
However, if most applications that support external
sync will be able to supports the Traveler's word
clock sync capabilities. Consult chapter 3,
"Installing the Traveler Hardware" (page 17) and
use the synchronization diagrams in that chapter
to synchronize your software and the Traveler to
the other components of your system.
