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 monitoring input,
choose a higher
Samples Per Buffer setting.
Depending on your computer’s CPU speed, you
might find that settings in the middle work best.
The Samples Per Buffer setting also impacts how
quickly your audio software will respond when you
begin playback, although not by amounts that are
very noticeable. Lowering the
Samples Per Buffer
will make your software respond faster; raising the
Samples Per Buffer will make it a little bit slower, but
barely enough to notice.
Monitoring live inputs without plug-in effects
As mentioned earlier, CueMix FX allows you to
monitor dry, unprocessed live inputs with no delay
at all. For complete details, see chapter 8,
“Reducing Monitoring Latency” (page 61).
Use stereo pairs for Windows audio
Some legacy Windows audio applications require
audio channels to be grouped in stereo pairs. If you
are using old Windows audio software, and you are
having issues accessing 828x channels from within
the software, try enabling the
Use Stereo Pairs for
Windows Audio option.
Use WaveRT for Windows audio
If your host software supports WaveRT, enable this
option. Consult your host application
documentation for details.
Enable Pedal
Check the Enable Pedal option if a foot switch is
connected to the 828x and you would like to trigger
recording punch in/out (or other software
functions) with it. Use the Set buttons to determine
what keystroke is triggered by the pedal-up and
pedal-down positions. You can assign the pedal to
any two keystrokes you wish. (You are not
restricted to punch in/out.)
828X TAB SETTINGS
Phones Assign
The Phones Assign setting lets you choose what you
will hear from the headphone jack. Choose Main
Out 1-2 if you’d like the headphone output to match
the main outs. Choose Phones 1-2 if you would like
the headphones to serve as their own independent
output, which you can access as an independent
output destination in your host audio software and
as an output destination for the four on-board
CueMix FX mix busses.
Optical input/output
The Optical input and Optical output settings let
you choose between 8-channel ADAT optical
(‘lightpipe’) and stereo S/PDIF optical
(‘TOSLINK’) as the format for the 828x’s optical
input and output. Choose the format that matches
the device connected. If you are not using the
optical connections, it is recommended that you
turn them off (by choosing
Disabled from the
menu) to reduce bandwidth and processing
overhead. Note that you can operate each optical
port independently. For example, you could use the
ADAT optical format on the input (for a digital
mixer) and optical S/PDIF on the output (for a
DAT deck).
Main Out Assign
Choose Main Outs from the Main Out Assign menu
to treat the Main Outs as their own independent
output pair. Choose any other output pair to cause
the MAIN OUT jacks to mirror (duplicate) the
output pair you choose.
Return Assign
The Return Assign menu lets you choose any pair of
828x audio outputs. The audio signal from this
output pair is then sent back to the computer via
the
Stereo Return 1-2 bus. This stereo return bus
from the 828x appears in your host software
alongside all other 828x inputs, wherever your host
software lists them.
