24. Configuring the ADI-2/4 Pro SE
24.1 Settings Dialog
Configuration of the ADI-2/4 Pro SE is usually done directly at the unit. For ASIO operation sample
rate and buffer size (latency) can be set via a dedicated settings dialog. The panel 'Settings' can
be opened by clicking on the fire symbol in the Task Bar's notification area
Any changes made in the Settings dialog are applied immediately - con-
firmation (e.g. by clicking on OK or exiting the dialog) is not required.
However, settings should not be changed during playback or record if it can be avoided, as this
can cause unwanted noises. Also, please note that even in 'Stop' mode, several programs keep
the recording and playback devices active, which means that any new settings might not be ap-
plied immediately.
Buffer Size
The setting Buffer Size determines the latency between incoming and outgoing ASIO and WDM
data, as well as affecting system stability.
USB Diagnosis shows specific USB
transmission errors (CRC5/16, usually 0)
and general errors. If the unit detects a
record or playback error the number
shown will no longer be 0. An audio reset
is performed automatically. The counter is
reset on start of playback/record.
Sample Rate
Sets the currently used sample rate. Of-
fers a central and comfortable way of con-
figuring the sample rate of all WDM de-
vices to the same value, as since Vista the
audio software is no longer allowed to set
the sample rate. However, an ASIO pro-
gram can still set the sample rate.
During record/playback the selection is
greyed out, so no change is possible.
The tab
About includes information about
the current driver and firmware version
plus two more options:
Lock Registry
Default: off. Checking this option brings up a dialog to enter a password. Changes in the Settings
dialog are no longer written to the registry. As the settings are always loaded from the registry
when starting the computer, this method provides an easy way to define an initial state for the
ADI-2/4 Pro SE.
Enable MMCSS for ASIO activates support with higher priority for the ASIO driver. Note: At this
time, activating this option seems to be useful only with the latest Cubase/Nuendo at higher load.
With other software this option can decrease performance. The change becomes active after an
ASIO reset. Therefore it is easy to quickly check which setting works better.
