I would like the vertical bar lines (and therefore also all the vertical quantize lines within each bar) of the project window and editor window to automatically align with each other at all times, no matter where Cubase is or moves within the project or editor window. How can this be done?
If you are referring to the Key Editor in the Project Window’s Lower Zone, then activate the button in the Lower Zone labeled “Link Project and Lower Zone Editor Cursors” - it looks like 2 links in a chain. If you can’t see the button use the gear configuration button to make it visible.
If you want to align the Key Editor in its own floating Window & the Project Window, you can’t. They are totally independant of each other and can be different sizes and shapes
