‘GENERAL’ TAB SETTINGS
Sample Rate
Choose the desired Sample Rate for recording and
playback. The 8pre USB can operate at 44.1 (the
standard rate for compact disc audio), 48, 88.2 or
96KHz. Make absolutely sure that all of the devices
connected digitally to the 8pre USB optical
connectors match the 8pre USB’s sample rate.
☛
Mismatched sample rates cause distortion and
crackling. If you hear this sort of thing, check the
sample rate settings in your hardware and here in
MOTU Audio Console.
Samples Per Buffer
The Samples Per Buffer setting lets you reduce the
delay you hear when patching live audio through
your audio software. For example, you might have
a live guitar input that you would like to run
through an amp simulation plug-in that you are
running in your host audio software. When doing
so, you may hear or feel some “sponginess” (delay)
between the source and the processed signal. If so,
don’t worry. This effect only affects what you hear:
it is not present in what is actually recorded.
You can use Samples Per Buffer setting to reduce
this monitoring delay—and even make it
completely inaudible.
☛
If you don’t need to process an incoming live
signal with software plug-ins, you can monitor the
signal with no delay at all using CueMix FX, which
routes the signal directly to your speakers via
hardware. For details, see chapter 9, “CueMix FX”
(page 47).
Adjusting the Samples Per Buffer setting impacts
