WORKING WITH HOST AUDIO SOFTWARE
60
Specifying the number of computer channels
In the web app Device tab (page 14), in the
Computer Setup section, you can specify the
number of computer channels for streaming audio
to and from your host audio software. You might
want enough channels to cover the following:
■ Physical inputs you want to record on your
computer.
■ The physical outputs you want to send audio
playback to.
■ Any audio streams going to and from the
on-board mixer in your MOTU device.
■ Any audio streams going to and from the AVB
network, if you have multiple networked MOTU
AVB devices.
If you aren’t sure how many channels you’ll need,
visit the Routing tab, as explained below.
Making inputs and outputs available to your
host software
In the web app, use the Routing tab (page 15) to
map inputs and outputs to computer channels, as
demonstrated in Figure 7-6 and Figure 7-7.
Configuration presets
The presets menu (item #7 in the Devices tab on
page 12) provides many useful presets for various
host routing scenarios. These presets are a
convenient shortcut for the routing grid setups
discussed in the next few sections.
Naming computer input and output channels
Click on any computer input or output name in the
routing grid (Figure 7-6) to change its name. These
names appear in your host audio software.
Figure 7-7: An example of routing physical inputs on the LP32 to computer channels (for host audio software).
