UAD Powered Plug-Ins Manual v5.2 - Just Music

Multi-DSP UAD-2 systems use significantly enhanced load balancing routines.
UAD-2 plug-ins are always allocated as efficiently as possible, which is not
necessarily on the DSP with the lowest resource usage.
More Loading
Notes
• UAD DSP usage is proportional to the host application sample rate and system
PCI/PCIe bus speed. Therefore, more plug-ins can be used simultaneously
in a 44.1K session than in a 96K session, and likewise a higher
speed bus will use less DSP load than a slower bus.
• Bypassing individual components will conserve DSP on some UAD plug-ins.
For example, bypassing the compressor in the EX-1 when only the EQ is in
use, and/or bypassing any of the unused bands of the EX-1 EQ will use less
UAD DSP.
• The UAD DSP resources required by each successive UAD Powered Plug-In
instance will slightly decrease.
• A chart showing expected plug-in counts can be found on our website:

Host CPU Loads
• The host system memory and CPU are never used for Powered Plug-Ins processing.
However, there will always be a small amount of load on the host
CPU induced by data transfers and user interface operations. This is unavoidable
when using a DSP card.
• When LiveTrack Mode is active, host CPU load is increased. See “LiveTrack
Mode” on page 78 for details.
Automation
Every UAD Powered Plug-In parameter can be automated if this feature is supported
by the host application. Each host application has its own particular
methods for automation. Consult the host application documentation for specific
instructions on using automation with the application.
UAD Powered Plug-Ins reduce their DSP load when bypassed or disabled, but
not their memory load. This feature allows for automatable load balancing of
DSP power, and keeps the track delay constant to avoid on/off clicks.
Note: If there is not enough DSP available when automating, the plug-in may
not turn on. When this occurs, “DISABLED” is displayed in the UAD Toolbar.
