hey guys I am using Cubase 7 in windows 8 64 iam using vs studio 100 interface by Roland and it keeps silencing itself . anyone have any ideas works great elsewhere

Aloha p and welcome to the board.

When you posted:

works great elsewhere

This then sounds like a driver prob to me.

So the question;
is the studio 100 interface
‘C7 ready’ (as far as up-to-date drivers etc)?
Best to check with the Roland folks on this.

If the drivers are compatible with C7,
then try increasing your buffer settings
a bit to see if that helps.

HTH (hope this helps)

Have you got the studio 100 ASIO driver selected in the Cubase set up.
