Latency and Required CPU
A particular computer configuration (i.e., processing speed
and memory size) may affect the computer's ability to prop-
erly record and play back audio data in your DAW, resulting
in noise or other audio problems. In most cases, you can
solve these problems by adjusting the latency (delay time), as
described below on this page).
However depending on the performance of your computer
and on how it is being used (i.e., whether other applications
are being used simultaneously, or whether multiple mLAN
devices are connected, etc.), you may still experience noise
or sound interruption even after increasing the latency. In this
case, change the "Required CPU" setting to "Medium Perfor-
mance" or "Low Performance" to lighten the processing load
on your computer, and then adjust the latency (the Preferred
Buffer Size setting in the right column on this page) once
again.
• Lower latency values result in shorter delay times and
work better for real-time recording and playback.
• Higher latency values result in longer delay times, but
allow for use of more audio channels and plug-in effects
(thus reducing the computer's momentary processing
load).
Conversely, if you experience no noise or interruptions even
with the "Preferred Buffer Size" setting (described at right)
set to the minimum, you can minimize the overall latency by
setting Required CPU to "High Performance" and then
adjusting the latency once again.
Latency of mLAN Driver
Audio latency
Audio latency is determined by the "Preferred Buffer
Size" setting in the "ASIO Control Panel." The audio
latency value is shown in the "ASIO Control Panel" (see
the right column on this page).
MIDI latency
For information on the MIDI latency, refer to the
"releasenotes_e.pdf" file.
ASIO Control Panel
When using the ASIO Driver, open the ASIO Control
Panel associated with the driver settings of the DAW soft-
ware (the specific menu depends on the software you are
using) and set the Preferred Buffer Size as needed. When
you open the ASIO Control Panel, the following dialog
box appears.
NOTE
• Also, when using the WDM driver, adjust as necessary the latency
value of the WDM driver (which corresponds to the latency of the
ASIO driver in this chart) within the driver settings of the DAW
software.
• The initial setting of the Preferred Buffer Size of the ASIO driver
is the smallest value.
