Hi guys, For one of my setups I am using a HD500 as a USB interface running off mainstage on Mac. Anyway, wondering how to configure it so that I can use four outputs on the HD500. I currently just use the XLR outs, but i read that with the 500x you can route two stereo chains through the XLR and the 1/4" outs. Hope this makes sense
