WORKING WITH HOST AUDIO SOFTWARE

Figure 7-5: When adjusting the buffer size to reduce monitoring
latency, watch the ‘processor’ meter in Digital Performer or
AudioDesk’s Performance Monitor. If you hear distortion, or if the
Performance meter is peaking, try raising the buffer size.
If you are at a point in your recording project where
you are not currently working with live, patched-
thru material (e.g. you’re not recording vocals), or
if you have a way of externally processing inputs,
choose a higher buffer size. Depending on your
computer’s CPU speed, you might find that settings
in the middle work best (256 to 1024).
Transport responsiveness
Buffer size also impacts how quickly your audio
software will respond when you begin playback,
although not by amounts that are very noticeable.
Lowering the buffer size will make your software
respond faster; raising the buffer size will make it a
little bit slower.
Effects processing and automated mixing
Reducing latency with the buffer size setting has
another benefit: it lets you route live inputs through
the real-time effects processing and mix
automation of your audio software.
WORKING WITH THE ROUTING GRID
The Routing grid (Figure 7-6) gives you a lot of
control over the audio routing to and from your
computer, as explained in the following sections.
Enabling and disabling input/output banks
In the web app Device tab (page 13), you can
enable all 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. Be sure to keep at least
one input and output bank enabled, though.

being split to two pairs of outputs: Phones L-R and Analog 1-2.
