UAD Powered Plug-Ins Manual - 60 - Using UAD Powered Plug-Ins
DSP Usage
The UAD card features an on-board CPU and 4 MB of memory for processing
Powered Plug-Ins. The host system memory and CPU are never used for Pow-
ered Plug-Ins processing. However, there will always be a small amount of
load on the host CPU induced by PCI data transfer and user interface opera-
tions. This is unavoidable when using a DSP card.
UAD CPU usage is proportional to the host application sample rate and sys-
tem PCI bus speed. Therefore, more plugins can be used simultaneously in
a 44.1K session than in a 96K session, and likewise a higher speed PCI bus
will use less CPU load than a slower bus.
Bypassing individual components will conserve CPU. For example, bypass-
ing the compressor in the EX-1 when only the EQ is in use, and/or bypass-
ing any of the unused bands of the EX-1 EQ will use less UAD CPU.
The UAD CPU resources required by each successive UAD Powered Plug-In
instance will slightly decrease.

Tempo Sync
As of version 4.0, the time-based parameters of several UAD Powered Plug-
Ins can be synchronized to the tempo of the host application using the Tempo
Sync feature.
When Tempo Sync is activated, the time-based parameters that are available
for synchronization are changed to note duration values, and will sync to the
tempo of the host application using the displayed note value.
Note: Not all host applications support Tempo Sync. In such hosts, the tempo
sync features will not function.
