Ok I checked the settings…..

The pedals are set to MIDI THRU and Midi Clock out is Off.

I have a friend that have the same pedals, and same problem. Also I knew a person in another guitar's forum that have MD and PF and a third stompboxes(another brand) with midi in/out, he has the same problem …..

Could you check this situation? I think that there some bug or problem on midi
