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 29.
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.
