Old problem with Cubase, and the same in Nuendo. When you Shift and turn the mouse wheel, you have horizontal scrolling (not described in the manual, by the way). With Alt, you have vertical scrolling.
With Eucon, you should have this function. Pro Tools (again!) has a very important Jog scrolling function in Eucon. It’s not the cursor that moves, it’s the scrolling of the screen, as shown above with the mouse.
I don’t think this function exists in Eucon for Nuendo, and I tried to find it again today: nothing.
If I’m wrong, please let me know. If I’m right, it becomes a feature request.
