Hello,
Yesterday I noticed my Grandmothers attack know suddenly stoped working. I can turn it up all the way but the note still instantly turns on.
If i patch from -env out into vca in and twist the attack knob while i press a key I can hear its doing something. (is there a better patch point top test this with?) But when all patch points are taken out… the attack know no longer works. Release knob seems to work fine.
I have updated the firmware to the latest version. But the problem is still here. 
Help!
