Program
This resource shows how much UAD-2 program memory 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-2 plug-in uses a bit of program memory. If many different UAD-2
plug-ins are loaded simultaneously, it is possible for this resource to run out before DSP
overload occurs. This point is considered and factored in by the automatic UAD-2 load
balancing routines.
Memory
The Memory gauges indicate the percentage of UAD RAM that is currently in use. It indi-
cates the total available UAD memory available, regardless of the number of DSP proces-
sors 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.
