Thanks Aj,
I always know that I can count on you.
Next time I'll just e-mail or call.
At first I also thought that the problem may be related to different FX being used. SO I bypassed everything and still noticed the same difference.
I got some interesting results by messing with knobs )Arp FX) but only got close.

I will definitely mention this to CHarmane Denisson from Yamaha. Hopefully she knows what the answer to that puzzel is.

In a way it is good that we both found the same problem since I originally thought that something is wrong at my end. Looks it it is just some internal bug that got overlooked by Yamaha.
