Joanne, maybe I missed the point, but what actually is the new Windows interface called? Or maybe not released yet? I've used ASIO4ALL with my Behringer UMC22 and seems to work bt peole do have varying expereinces with it (no doubt often hardware related). It is a pity that Windows does not have a native solution for low latency audio interfaces and applications so if they are adding one it can only be good I would have thought. However, as ASIO operates "outside" of Windows I can see the issues.
