I made a clean install with cubase 6 and then MR816 X/CSX driver/extension. In the tamplate dialog there is no option for the MR816 audio card. > No options to use the card in the mixer. This is embarrasing cause both yamaha/Steinberg products. Should work without no problem.
I found the solution to the problem. I choose “open other” template. Then search for C:/program/cubase5/template. If some other has the desame problem here is the answer.
