Ah, I see you've made some changes to Low Level Boost. I turned it back on and it seems to solve a lot of the "fade in" types of issues I was seeing. It also sounds good again.
So like the Single Band Compressor, the Low Level Boost has a "Symmetry" setting. On the Single Band Compressor, it enables when selecting "Symmetrical RMS" mode. On Low Level Boost, it is enabled by default and disables when selecting "Legacy" mode. On both modules, the default setting is 3.3x. On Low Level Boost, when "Symmetry" is enabled (not in Legacy mode), "Ratio" and "Big Release Acceleration" are disabled. When Legacy mode is engaged, Symmetry disables and Ratio / Big Release are enabled. On the Single Band Compressor, "Symmetry" also defaults to 3.3x, and enables when "Symmetrical RMS" or "Symmetric Averaging" is selected. When these modes are selected, "Big Release Acceleration" and "Sudden Attack Slowdown" are disabled. However, "Ratio" (as well as "Max Ratio") stay enabled for all modes here.
What is true for the Single Band Compressor is also true for the Multi Band Compressor, with the settings split between "Detection" and "Behavior". (Although for the first Multi Band Compressor - the Digital One - Symmetrical RMS doesn't actually get used, according to release notes.)
So my question is: What does the "Symmetry" multiplier do exactly? What happens when it's turned up? And also, why is "Ratio" disabled for Low Level Boost, but not for the compressors (since I'm guessing Low Level Boost is functioning similar to a compressor)?
goaliebob99, try enabling Low Level Boost. You have to select "Extreme Tweaker" Operating Mode on "Configuration" to see it.
