UAD Plug-Ins Loads
The amount of UAD resources used by UAD plug‑ins vary with each individual plug‑in;
more complex algorithms require more resources.
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 assign with
available resources. The chart is published online at:

DSP
The DSP meter displays the amount of digital signal processing resources that are being
used by UAD‑2 Live Rack. DSP is the primary hardware resource that powers the UAD
plug‑in algorithms.
Note: When UAD plug-ins are disabled, DSP requirements are decreased EXCEPT
when the plug-in is disabled using the Power control within the plug-in interface.
Program
This resource meter shows how much program memory (PGM) is in use. Program memory
is an on‑chip memory that is specific to the SHARC processor(s) and is used for certain
UAD plug‑in resources.
Each unique UAD plug‑in uses a bit of program memory. If many different plug‑ins are
loaded simultaneously, it is possible for this resource to run out before a DSP overload
occurs. This point is considered and factored in by automatic load balancing routines.
Memory
The Memory (MEM) meter indicates the amount of UAD‑2 Live Rack hardware RAM that
is currently in use.
Memory is used for echo, delay lines, reverb, and similar 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.
