So we have only (4) analog outputs with Montage, (2) main and (2) individual. I need/want 8 or 16 analog outputs. I know we have the USB outs to computer which are digital. Is there a USB post-computer HUB device that will receive all channels via a single USB cable and then output them on individual analog channels? Not only do I want to route digital channels freely but I also want to route all of the analog channels as well, however I choose.
