Figure 10-6: 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, but barely enough to notice.
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.
CUEMIX FX HARDWARE MONITORING
The 896mk3 has a more direct method of patching
audio through the system. This method employs
the 896mk3’s
CueMix FX digital mixer. When
enabled, CueMix activates hardware patch-thru in
the 896mk3 itself. CueMix FX has two important
benefits:
■
First, it completely eliminates the patch thru
delay (reducing it to a small number of samples —
about the same amount as one of today’s digital
mixers).
■
Secondly, CueMix FX imposes no strain on the
computer.
The trade-off, however, is that CueMix FX
bypasses your host audio software. Instead, live
audio inputs are patched directly through to
outputs in the 896mk3 itself and are mixed with
disk tracks playing back from your audio software.
This means that you cannot apply host-based
plug-ins, mix automation, or other real-time
effects that your audio software provides. But for
inputs that don’t need these types of features,
CueMix FX is the way to go.
On the other hand, if you really need to use the
mixing and processing provided by your audio
software, you should not use CueMix FX. Instead,
reduce latency with the buffer setting (as explained
earlier in this chapter).
TWO METHODS FOR CONTROLLING
CUEMIX FX
There are two ways to control CueMix FX:
■
With CueMix FX
■
From within your host audio software (if it
supports direct hardware monitoring)
You can even use both methods simultaneously.
Using CueMix FX
If your host audio software does not support direct
hardware monitoring, you run the CueMix FX
software side-by-side with your audio software and
manage your monitor mix in CueMix FX.
CueMix FX allows you to create up to eight
separate 896mk3 stereo mixes, or any other desired
routing configurations. These routings are
