Happy for you that you found some way to get 2.1.1 to work for you!
I´m still out of luck, I´m afraid.
Another Go, another system and rig reset and another time upgrading to 2.1.1 - it is still too harsh, loud and fizzy.
Even changing Distortion Sense to -5 it does not go away completely. (Clean Sense on 2.5).
So I´ll stick with 2.1.0 until after the gig and maybe until there is a new FW available.
I don´t want to incur the wrath of Mr. Kemper - I´m just describing some issues within my experience and my in-ability to counteract them!
Peace!
