Good morning, I have one doubt in relation to a pod of efeio hd 500, which is the smart harmony (which doubles the guitar, and is duets), good place effect settings as well Key: C lollipop: 3rd and then Major MIX: 50%, start to improvise in C Major just seems that the effect of the notes are not married duet, what would that be, someone could help me, would be a failure to update the pedal?
