11.3 Tab Global 
This tab includes several options that work on all currently installed cards. 
Lock Registry 
Default: off. Checking this option brings up a dialog to enter a password. Changes in the Set-
tings 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 
of the HDSPe MADI FX. 
Optimize Multi-Client Mixing 
Default: off. Checking this option 
removes short noise bursts when 
multi-client playback starts, but will 
also introduce some additional CPU 
load. 
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. 
ASIO 32 Channel Limit 
Default: off. Checking this option limits 
the number of ASIO I/Os to 32. 
Reducing the number of ASIO 
channels is required for older versions 
of ProTools to prevent them from 
crashing on start-up. 
Change Card Order 
This dialog lists all cards currently installed in the system and controlled by the driver. Their 
order can then be changed by selecting a card and using the up/down arrows. Confirm the op-
eration with the Apply button. This feature comes in handy if different cards are installed and a 
specific one of them should always be the first in the ASIO channel list. 
At the end of the card info line the current firmware version is shown (Revision).
