Known issues with Cubase 7 and MR

Stefan,

I was running Cubase 6.5.3, with MR816 and CC121 under Windows 7 64 Ultimate.
Running great. 6.5.4 was causing problems, hick-ups, so got back to 6.5.3.
6.5.3 is also running smooth under windows 8 pro.

Cubase 7 and MR816X, does not matter windows 7 or 8, is not working.
Can’t play a single project, just hick-ups and stutter.
So frustrating!!!
Any advice?

Best regards and thanks in advance,
Twan
