Hi Wersi66, I also have a Tyros 5, but I don't have the MFC 10. But I think that beforehand, there is a whole programming to do. In my opinion, you should contact the technician at Yamaha, the dealer where you bought your keyboard or pedalboard, who can explain the procedure to you. For your information, I know that at the time, the Sud-Clavier store located in Mirepoix, sold this pedalboard.
