UAD Conﬁguration Window

The UAD Configuration Window (Figure 12 on page 49 and Figure 11 on

page 48) 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.
