MC6 MK II + DigiTech FS3X 3 Button Pedal => will they work (?)

Hi Morningstar !

My 1st post here. I have just ordered a MC6 MK II and I will need to attach a 3 Button Auxiliary Pedal with it. My local music store has one of these Digitech FS3X 3 Button Pedals in store ... my question is:-

=> will the Digitech FS3X 3 Button Pedal work as an external 3 button auxiliary swtich with the MC6 MK II (?)

=> if so, do I need to do anything special / different for the MC6 MK II to correclty recognise and use it (?)

Thanks,

Ben
