Direct out are exactly that, they effectively don’t get into the processing part of the channels so will miss DCA mutes etc. If i understand what he wants to do is to take the 16 individual channels in process them seperately then send the 16 staight out not summed. If you go into mixer config and remove all the busses you don’t use ie stereo and extra effects ones you may just be able to squeeze 20 auxes
