Italo,
1. Petja is on 5.5, I'm on 5.3. We both see serious problems.
–> Moving from 5.3 to 5.5 will very likely NOT fix the problem.
2. I have tested several pedals and switches, and what is more, they all work well with my GTR 4000 in the same applications.
–> it is very likely a H8000FW issue, probably an unknown SW issue.
Thabks,
Thomas
