Thanks to Jazzman/Noel for immediate help...

Went to the Song Settings and the transpose check was set to 0.
Ok, I set it at +4 (F to A) and it worked!

I have not checked it with other/new compositions (OK, I am retired, dont stress, guys!) but will do in the next days and report...

When I came back to the Song Settings it was set to 0.
So I expect I am "correctly tuned" now.
