Enabling and disabling input/output banks

In the web app Routing tab (page 15), you can 
enable any input and output banks on your MOTU 
device that you wish to make available to your host 
audio software. You can disable banks you are not 
using to simplify operation.

Specifying the number of computer channels

In the web app Routing tab 

Enable Inputs/Outputs 

sections (Figure 7-6), 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.

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) t
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.

Figure 7-7: An example of routing all eighteen physical inputs on the UltraLite-mk4 to computer channels (for host audio software).
