Modiﬁer Key

(Mac OS)

The Modifier Key drop-menu allows you to specify which modifier key will be

used for the “set to last saved value” keyboard shortcut. It also affects the “se-

lect + click” modifier. This feature is not supported under Windows. For a

complete list of keyboard shortcuts, see “Shortcuts” on page 33.

PCI Bus Settings MIN_GNT is a low-level system setting that affects PCI bandwidth. The default

value of 64 is recommended for most systems. If you are experiencing crack-

les or dropouts, our technical support team may recommend a different value.

Important: System performance can be adversely affected by changing this

setting. This parameter DOES NOT AFFECT AUDIO LATENCY in any way!

AMD-8131

Mode

If your computer uses the AMD-8131 PCI controller chipset, check the “AMD-

8131 Compatible” box. This will improve UAD performance on these sys-

tems. For the new setting to take affect, you must reset the ASIO device using

one of the following methods:

•Close the re-open the session

•Stop then restart the audio engine

•Modify or reset the audio device settings

Note: Do not enable AMD-8131 Mode unless your computer uses this PCI

controller chipset. AMD-8131 Compatible Mode is only required when the

card is attached directly to an AMD-8131 PCI bus. If the UAD is in an external

PCI expansion chassis, this mode should be disabled (unchecked).

Macintosh G5 Systems

The AMD-8131 chipset is used in most Macintosh G5 systems. The UAD soft-

ware automatically determines when it is running on a G5 with AMD-8131

and sets the mode appropriately. If the UAD is in an external PCI expansion

chassis, AMD-8131 mode should be unchecked.
