I’ve never actually heard of pedal harmony anywhere else, and I’ve done some google searches and can’t find anything about it. I only sort of grasp the concept and was hoping to mess around with it on Hook Pad but I don’t think it’s possible.
The video in section 5.5 seems to be of Hook Pad using pedal harmony and the “V/1” or “five over one” notation, but I can’t for the life of me figure out how to make Hook Pad do that.
