I'm trying to figure out a way to use my KPA for acoustic and electric in a live setting. Before anyone says "Just run everything out the main outputs" - that is not an option for my scenario 
I need to find a way to run electric out the main outs, and acoustic out the direct send and have control over the output of both. I don't need both at the same time, fortunately.
Is there a way to rig the direct send to go to a DI and control the volumes of these individually?
So when acoustic is on, the main outputs are muted and the direct send is on, and vice versa for the other scenario?
Thanks!
