UAD Configuration Window
The UAD Configuration Window (Figure 12 on page 45 and Figure 11 on
page 44) displays additional information about the UAD card and is also
used to modify some UAD settings.
Latency
Calculator
The number of active UAD Powered Plug-Ins, the sample rate, and the current
buffer size are displayed. The window uses this information to calculate and
display the resulting latency in milliseconds. In Mac OS, the latency calculator
is displayed in the System Information window.

Configuring Extra Buffers
Extra Buffers are required when “Buffer Size” displayed in the UAD Configu-
ration Window is smaller than the actual ASIO buffer size selected for the ac-
tive ASIO hardware device.
Note: Extra Buffers are not required for Cubase/Nuendo version 2 or
higher, Logic Audio, or Mac OS.
This situation may occur when users of Steinberg Cubase and Nuendo select
ASIO buffer sizes of 2048 samples or greater, or when UAD Powered plug-
Ins are used with a DirectX wrapper. If the situation is not corrected, the use
of UAD Powered Plug-Ins will introduce excess host CPU load.
To configure the UAD for Cubase and Nuendo large ASIO buffer size support:
1. Launch the UAD Performance Meter.
2. Open the system menu by clicking the icon at the upper left of the Perfor-
mance Meter and select the ‘Configuration’ option.
3. Increase the Extra Buffers control until “New latency” matches the current
buffer size of the ASIO device.
4. 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
5. The “Current latency” display should now match the “New latency” dis-
play. Configuration of Extra Buffers is complete.
