Monitoring through the 828es
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 the
828es to route the input directly to your outputs.
For details, see “Mixing tab” on page 16. The
mixer in the 828es 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
the 828es 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
the 828es 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 Pro
Audio Control web app mixer (“Mixing tab” on
page 16) 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 the 828es. This is done by
opening the Mix In group in the Outputs column
along the left side of the grid, 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.
In either case (routing directly in the grid or
routing through the mixer), be sure to maintain
the input’s connection to the computer as well, so
the input signal can be recorded in your host
software. In other words, you’ll want to make sure
there are two tiles enabled in the input’s column in
the grid: one tile for the connection to the
computer and another tile for your monitoring
output (or a mixer input, if you are using the mixer
to apply effects). If you need to route the input
signal to other destinations, too, you can certainly
do so (you can route the input to multiple destina-
tions).
Monitoring through your host audio software
If you do need to process a live input with host
software plug-ins, or if you are playing virtual
instruments live through your MOTU audio
hardware, you can significantly reduce latency by
adjusting the audio buffer setting in your host
audio software, as explained in the next section.
☛ It is important to note that monitoring delay
has no effect on the recording, or playback, of
audio data from disk. The actual recording and
playback is extremely precise, it is only the
monitoring of your live input signal which may be
delayed.
Adjusting your host software audio buffer
Buffers are small bundles of audio data. The 828es
“speaks” to your computer in buffers, rather than
one sample at a time. The size of these buffers
determine how much delay you hear when
monitoring live inputs through your audio
software: larger buffers produce more delay;
smaller buffers produce less.
