I want to put the song on loop and record my mixing board movements volume/EQ live. So that when the song plays the second time through and I did not get the high hats to fade in or the sidechain right, in one spot, I can adjust it as its playing without overwriting the previous automation. I want this for all armed tracks. The mixer board should remember the values and be motorized. Is this something people do? or do they just create automation lanes and draw in the volume/eq values?
