It's been a while, but I can confirm.
But possible that levels on filters are different making longer time until decay is done, not sure.
I also looked into setting regarding VCA curve settings, and difference remain for decay. depending on filter.
About attack curves I can sense no difference at all if using either filter, but no difference regarding curve selected either.
So will report to support regarding this if a firmware is about to be updated.
Almost a year since last now.
Could be a thing that should be part of some calibration when doing All, and VCA is included.
