I´ve changed the transmit channel to #16 created 02 banks with pedalboards and tried to switch pedalboards or banks with no success but suddenly the "midi learn' on/off started to occasionally work as toggle switch.
To made sure i changed the midi cable but got the same behavior.
I´m starting to think of a bug.
The MOD will replace the GT-10 in my setup so I will not pursue a solution on this matter any more but I´ll need some kind of foot control specially for a live setup,
MIDI is the first option that comes to my mind but I´m interested to know more about the "Control Chain" (ethernet) port of the MOD.
