Hi info on using midi foot controller for the first time with MG3

Hi
so I have quite a few sounds now saved to my midi guitar 3 on Mac. I have never used a midi foot controller before but I want to be able to switch between saved patches or store up to four patches in a pedal which ever is easiest. Im not using any other software and dont have a clue about other software just using midi guitar 3 and some synth vsts for leads and pads that I want to use now and again for live do I connect the controller into the Mac or audio interface cheers

If you have a footcontroller connected to your computer, you can set it to send CC 14-15 and control patch up/down.
