If the material you are recording is suitable, there is
a third way to monitor live input: use both methods
(Figure 10-1 and Figure 10-2) at the same time. For
example, you could route guitar to both the
computer (for an amp model effect) and mix that
processed signal on the main outs with dry guitar
from CueMix FX — or perhaps with a touch of
896mk3 Classic Reverb.
ADJUSTING THE AUDIO I/O BUFFER
A buffer is a small amount of computer memory
used to hold data. For audio interfaces like the
896mk3, buffers are used for the process of
transferring audio data in and out of the computer.
The size of the buffers determines how much delay
you hear when monitoring live inputs through
your audio software: larger buffers produce more
delay; smaller buffers produce less.
Under Mac OS X, audio I/O buffer size is handled
by the host audio application (not the 896mk3
Core Audio driver). Most audio software
applications provide an adjustable audio buffer
setting that lets you control the amount of delay
you’ll hear when monitoring live inputs or
processing them with software plug-ins. Below are
a few examples.
2. CueMix FX immediately patches the
live mic signal directly to the main outs
(or other output), completely bypassing
the computer. This signal could be dry, or
with 896mk3 effects processing, such as
EQ, compression or Classic Reverb.
3. Mic signal is mixed with the main outs, and you
can control the volume (relative to the rest of the
mix) with the mic’s fader in CueMix Console.
Figure 10-2: This diagram shows the signal flow when using CueMix FX no-latency monitoring. Notice that this method does not process the
live input with plug-ins in your audio software. Instead, you can apply 896mk3 effects, such as the reverb, EQ and/or compression.
1. Live input (from mic,
guitar, etc.) enters the
MOTU interface.
