UAD Plug-In Loads
The amount of UAD resources used by UAD plug‑ins vary with each individual plug‑in;
more complex algorithms require more resources.
UAD Instance Chart
The amount of DSP used by each individual UAD plug‑in is available in the UAD
instance count chart. The chart can help determine which to plug‑ins to use with
available resources. The chart is published online at
.
Static Loads
UAD‑2 Live Rack uses DSP and memory for its internal digital mixer and Input Delay
Compensation engine. Therefore, the meters will indicate loads when UAD‑2 Live Rack is
connected, even if UAD plug‑ins are not currently inserted.
Note: UAD-2 Live Rack’s Delay Compensation engine can be disabled in Delay
Groups View to slightly reduce UAD loads when delay compensation is not
needed.
DSP
The DSP gauge indicates the amount of digital signal processing resources that are being
used by all UAD‑2 Live Rack devices in the system.
DSP is the primary hardware resource that powers the UAD plug‑In algorithms. When
UAD plug‑ins are disabled, DSP requirements are decreased.
Note: When UAD plug-ins are disabled, DSP requirements are decreased EXCEPT
when the plug-in is disabled using the soft bypass control within the plug-in
interface. This control may be named bypass or power, depending on the plug-in.
Program
The Program (PGM) gauge indicates how much UAD program memory is in use. Program
memory is an on‑chip memory that is specific to the UAD‑2 DSP processor and is used
for certain UAD plug‑in resources.
Each unique UAD plug‑in uses a bit of program memory. If many different UAD plug‑ins
are loaded simultaneously, it is possible for this resource to run out before a DSP
overload occurs. This threshold is considered and factored in by the automatic UAD load
balancing routines.
Memory
The Memory (MEM) gauge indicates the percentage of UAD RAM that is currently in use.
It indicates the total available UAD memory available, regardless of the number of DSP
processors that are installed.
Memory is used for echo, delay lines, reverb, and other spatial processing. When UAD
plug‑ins are disabled but not unloaded, memory requirements are not decreased. In this
case, the memory remains loaded so that reverb tails and delay lines are not cut off when
the plug‑in is disabled.
