Deadbox Typhon why can´t I get a slow attack

Hey Nauts, so I tried to make an slow evolving pad sound with an slow Attack and long release. But when I turn the Attack up just to 10 no sound will come.
As I´m using it for a live set I want to programm in its internal Sequencer.

What am I missing? Anyone else with this “problem”

Cheers
Dustin
