WORKING WITH HOST AUDIO SOFTWARE
64
Conversely, you can stream audio from the
computer into the mixer. Channels coming from
the computer are represented across the top of the
routing grid as inputs. To route a computer channel
to the mixer, click the grid at the intersection of the
computer channel column and the desired mix
input row. Now, that computer channel will be
routed to the mixer input.
Working with AVB network streams
Audio channels going to networked AVB interfaces
can be streamed to and from your host audio
software through the MOTU interface connected
directly to the computer. For information about
how to set this up, see “Mapping computer
channels to network streams” on page 79.
Mirroring computer channels to multiple
outputs
Figure 7-1 shows an example of mirroring one
stereo audio stream from your host audio software
to several outputs. In the example, computer
channels 1-2 are being sent to the main outs, plus
phones 1-2 and phones 3-4. To route an input to
multiple outputs, click multiple boxes in its
column, (see computer channels 1-2 in Figure 7-1).
Combining multiple inputs to one output
To merge (mix) any channels in the grid (computer
streams or otherwise), route them to mixer inputs
and then use the on-board mixer (“Mixing tab” on
page 21).

CHOOSING THE MOTU AUDIO DRIVER
Once you’ve made the preparations described so
far in this chapter, you’re ready to run your audio
software and enable the MOTU audio driver.
Digital Performer and AudioDesk
In MOTU Digital Performer or AudioDesk, choose
Configure Audio System > Configure Hardware
Driver from the Setup menu. Choose 1248 (or
other MOTU interface model) from the list of
CoreAudio drivers.
Pro Tools
Go to the Setup menu and choose Playback Engine.
Choose 1248 (or other MOTU interface model)
from the Current Engine menu. For information
about the H/W Buffer Size setting, see “Reducing
monitoring latency” on page 65.
☛ Pro Tools 9 or later is required.
Logic Pro
Open the Preferences window, (click Audio tab ->
Devices tab -> Core Audio tab). Choose 1248 (or
other MOTU interface model) from the Output
and Input device menus.
Garage Band
In Garage Band, go to the Audio/MIDI preferences
(Garage Band drop-down menu -> Preferences ->
Audio/MIDI) and choose 1248 (or other MOTU
interface model) from the Audio Output and Audio
Input menus.
Cubase and Nuendo
Open the Device Setup window. Click the VST
Audio System item in the Devices list and choose
1248 (or other MOTU interface model) from the
VST Audio System menu. Activate the inputs and
outputs within Cubase or Nuendo as usual.
