I don't if this is a update or a bug. All of a sudden the Drive control on the Filters is affecting the Dry signal of the Filter.
If I set the Mix control on the Filter to just the Dry input signal. The Drive control now applies Drive to the Dry signal.
I'm hoping this is a bug becuase if this is a feature it would mean Serums Filters do not really have a Dry/Wet control anymore. This renders the Filters totally useless now for a lot of sound design applications.
I did try updating Serum 2. It didn't fix the issue.
