I don't know much about this interface so I looked it up.

Here's the specs page. Read the first thing under the SYSTEM REQUIREMENTS heading.

There could be a problem with the operating system since in the specs.... it doesn't list W8.1 as a compatible system. Nor did I see, in my quick look through the page, any mention on it's ability to use ASIO. It listed the first 2 editions of 64 bit OS's and nothing since.

I've never been a fan of the multifunction interfaces..... some folks are, but in my time helping folks in Cakewalk's forums, the multifunction interfaces were problematic at times due to them often using codecs and wrappers rather than ASIO.

MY SUGGESTION: Go to a store with a 100% no questions asked 30 to 45 day refund policy and buy a single purpose interface that's compatible with the newer OS's... W7 and W8.1 in 32/64 bit. Load the drivers and install it and see if it solves the issue. If it does, sell the Roland or find another use for it. If the new interface doesn't solve the issue, pack it up and return it and get your money back.
