or less, if your computer seems to be able to handle
them. If your host audio software has a processor
meter, check it. If it starts getting maxed out, or if
the computer seems sluggish, raise the Samples Per
Buffer until performance returns to normal.
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 59).
Enable Pedal
Check the Enable Pedal option if a foot switch is
connected to the 828mk3 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.)
Wave support for legacy (MME) software
Windows only exposes the first two channels of a
multi-channel WDM audio stream to applications
which use the legacy (MME) multimedia interface.
The Enable full Wave support for legacy (MME)
software (less efficient) option forces the 828mk3
multimedia driver to expose all channels as stereo
pairs, providing full MME support.
If your host audio software does not directly
support WDM audio and instead only supports
legacy MME drivers, use this option to access
multiple 828mk3 input and output channels.
If your host audio software does directly support
WDM audio, leave this option unchecked for
optimal performance.
This option is only available when the multimedia
driver has been installed, and it defaults to being
not checked.
‘828MK3’ TAB SETTINGS
Phones
The Phones setting lets you choose what you will
hear from the headphone jack. Choose Main Outs
if you’d like the headphone output to match the
Main Outs. Choose Phones 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 eight on-board
CueMix FX mix busses.
Optical input/output
The Optical input and Optical output settings let
you choose between ADAT optical (‘lightpipe’) and
S/PDIF optical (‘TOSLink’) as the format for the
828mk3’s two banks of optical input and output
(Bank A and Bank B). 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
