Hello, I am new to the world of midi. I was able to use my Helix to control my Eventide H9. But I can not understand how to change the amps on the Kemper via midi with the Helix (Rack). I love the sound I can get with both units. Can someone explain this to me please. Thank you so much. Jim![smile :)](https://forum.kemper-amps.com/wbb/images/smilies/emojione/263a.png)
