When I select a patch on my XP50, I sometimes have to press several patch-banks in order to hear the 'complete' sound. Some LEDs should be burning, indicating the bank is used and on. When I want to switch between to patches I have to press those banks again and again. When playing LIVE, this is getting irrating ;(

I think I'm doing something wrong, because it used to be okay.
Resetting my XP50 to the factory defaults doesn't seem to solve the problem.

Can someone guide me to the right solution?

THANX
