REDUCING MONITORING LATENCY
Monitoring latency is a slight delay caused by
running an input signal through your host audio
software and back out. For example, you might
hear it when you drive a live guitar input signal
through an amp modeling plug-in running in your
audio sequencer.
This delay is caused by the amount of time it takes
for audio to make the entire round trip through
your computer, from when it first enters an input
on your MOTU interface, passes through the
interface hardware into the computer, through
your host audio software, and then back out to an
output.
Monitoring through your MOTU interface
If you don’t need to process a live input with
plug-ins, the easiest way to avoid monitoring
latency is to disable your DAW’s live monitoring
feature and instead use the digital mixer in your
MOTU interface to route the input directly to your
outputs. For details, see “Mixing tab” on page 21.
The mixer in your MOTU interface even provides
zero latency effects processing (EQ, compression
and reverb), which can be applied to the signal.
Direct hardware playthrough / Direct ASIO
monitoring
When managing your live monitor mix through
your MOTU interface mixer, remember to disable
your DAW’s live monitoring features, so that you
won’t hear record-enabled tracks in your DAW.
Also note that your MOTU AVB interface does not
support Direct Hardware Playthrough in Digital
Performer, or the Direct ASIO Monitoring feature
(or similar) offered and other DAWs, which lets
you control no-latency hardware monitoring from
within the host application. Instead, you can use
the MOTU AVB Control web app mixer (“Mixing
tab” on page 21) to make these live monitoring
connections manually.
If you don’t require any effects processing on the
input signal (no reverb or compression, for
example), all this takes is one click in the routing
grid to route the input being recorded to the output
you are using for monitoring.
If you are recording a mono input that you’d like to
monitor in stereo, or if you need to apply effects to
the monitored signal, you can simply route the
input to the mixer in your MOTU interface. This is
done by opening the Mix In group in the Outputs
column along the left side of the grid (Figure 7-2
on page 67), and clicking the tile at the intersection
of the input’s column and the desired mixer input’s
row. Once routed to the mixer, use the input
channel, reverb bus, and monitor bus in the mixer
to apply effects as desired, and perhaps include
other channels to the mix, and then assign the
monitor bus output in the routing grid to the
output you are using for monitoring.
