Kemper controlled by Mac through midi

Hello everybody !
I just receives my KPA ! the sound is great

But i want to try to use my kemper with my mac through ableton live.
I want to create a midi track and then when i'm playing with a clock it change the FX and amp like a programmed it in this track.
So can i use the usb or should i use a Midi-USB cable? Does someone has already done it?

Thanks

I try last day to program something but nothing happened. I saw in the "reference manual" page 43 that i should use the soft knob "midi device ID" but i can't find this. any ideas ? can someone make a video tutorial for midi settings ?

It's possible to have more info in the manual about midi controlled by a computer? I try since a few days but i can't send midi to the kemper and change rig like i want. thx
