This question came in from Joe C. Not able to supply a direct answer so…

“I have the Rack ES and I am working with the VOICE :Fully sound which is an organ using 4 elements. I understand that I can not assign voices to the individual outputs but I’ve noticed that I can split up the 4 elements within this Voice using the four buttons “ 1/5/9/13, 2/6/10/1, (which is Part left and right), 3/7/11/15 (Common button) and 4/8/12/16 (which is the audition button. I can fade in and out using my mixer and the assignment outs while in the Performance mode, but I can’t while in the Voice mode except for using the buttons which only pops in and out. Is there a way of assigning these buttons to my faders on my mixer? I am trying to split up the four elements of this sound smoothly.”
