5.1.2 The Global Tab

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

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 interface.

Optimize Multi-Client Mixing

Default: off. Checking this option

removes short noise bursts when multi-

client playback starts, but will also

introduce a small 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 on interfaces

with high channel counts 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

operation 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.
