Sorry – don't understand.
sorry for my bad english i'm a german.
In the H8000 setup you can configure 8 assigns to 8 midi CC.
Than you set in a preset assign 1 and assign 2 to two differnt parameters. At 1st you take assign 1 set i.e. dry/wet with a range of min/max 50%. After them you set assign 2 to feedback and use a range of min/max of 80%. After you pressing done at assign 2, the assign 1's range is back to absolute 100% (not min/max 50%)
I hope you understand 🙂
