Static Loads
Apollo uses UAD DSP and memory for its internal DSP mixer, therefore the meters will
indicate loads (when the hardware is connected) even if UAD plug-ins are not inserted.
DSP
The DSP gauge indicates the amount of digital signal processing resources that are being
used by all UAD devices in the system.
DSP is the primary hardware resource that powers the UAD Powered Plug-Ins 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 Power control within the plug-in interface.
Program
The Program (PGM) gauge indicates how much UAD program memory (PGM) is in use.
Program memory is an on-chip memory that is specific to the UAD-2 DSP 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 UAD plug-ins
are loaded simultaneously, it is possible for this resource to run out before a DSP over-
load occurs. This point is considered and factored in by the automatic UAD load balanc-
ing 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 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.
