If you’ve got a login to the old forums here’s the thread covering the dual CV situation.
In short, the gate & CV outs are wired for dual use, but the OS doesn’t support it. Jean mentioned the possibility of support being added to a future OS update. Don’t hold your breath, the thread’s from September 2016.
You may be able to use the dual out like a duplicator, but I don’t know anything about Eurorack or have any experience with CV so dual by your own volition.
