Hey Stephen,
My Yamaha CP73 has been a pretty great board until now. I'm having a repeated issue where the sustain pedal works until I change patches. The only way to get the sustain back is to unplug it from behind and plug it in again. Then suddenly all is fine.
I have tried making sure that all sustain settings are set to ON, a full factory reset and different sustain pedals but the problem persists. There is no visible crack or issue with the port where the sustain plugs in either. I'm in a bit of a panic to resolve this as I have a tour that begins next week.
Thanks for any help,
Dan
