I’m sorry, but it doesn’t seem that there is any practical way to do this. Issues are mismatch in sample rate, clocking and such. If you wish to use this device strictly as an A/D converter you could find a good used analog board like a Midas Venice to use for the pre-amps, then the Aurora into your computer. Once you have the tracks in Cubase you MIGHT be able to get it to work with the Qu as your control surface, BUT…
This idea appears very impractical and a huge mis-application of funds. But if it’s what you want to do, then I wish you luck.
