Well, I recommend the Yamaha MFC 10! With this pedal you can choose upper and lower row for programm changes and via pressing the function button (also a footswitch) you get 10 CC buttons. Or you can switch to - upper row - CC and lower row for PC. It´s very, very easy to programm this pedal.

Also you can use the internal pedal (of cousre ) and there´s an option to connect 4 additional pedals or footswitches!!
I don´t need the option to tune my guitar via the foot controller. I prefer the big Display on my KPA Rack
It´s absolutely reliable and I don´t need a UnO update or anything else.
For me my perfect friend to tame my KPA
