Hi all. I have a PSR 3000 . I have two pedals set up. One for vocal harmony, the other for fills. The problem: when pressing the pedal for a fill, it just keeps on going.I have to press the pedal again to make it stop. I'm in the "fill self" mode on the setting. The fills work o.k if done manually. I have also tried switching pedals with the same result. Any ideas?, Thanx, Bob Lee
