I see a nice autoscrolling feature in the product video “cubase6 at a glance 4”.
(, the first few seconds of this vid )

How do i use it?

Are you refering to the page moving and not the cursor? If yes, it’s an old feature called Stationary Cursor located in Prefs.

Yes, i mean the page moves…

You mean preferences under “file” menu?

I gonna try it.

Yes, under Transport.
