As I just posted in the other thread ...
... from the info I got when the studio capture came out (
http://forum.cakewalk.com/FindPost/2762636) it seems it was not designed to work with the VS-700 ... hence I never considered using it ...
Edit: the post I was referring to is about 2 yrs old but meanwhile there have not been any driver updates for VS-700 (other than porting to win 8) which would have mentioned address this (VS-700 & Octa-Capture still use what Roland calls VS EXPAND, while the Studio Capture uses VS STREAMING technology)
