Marker lines in key editor (Cubase 10.5)?

Hey guys,
Is it possible to show marker lines in key editor also in Cubase 10.5? I have this guide:

But it’s from Cubase 11. Unfortunately I can’t use version 11 it’s buggy for me. I’m guessing it’s not supported yet in version 10.5? If not is there a workaround?

Thanks in advance

You’re right, they are a new C11 feature.

Don’t know about a workaround, sorry.


This feature is new in Cubase 11.

The workaround is strange the Key Editor window and the Project window so they are overlapping. You would need to sync the Zooms. Or you can use the In Place Editor in the Project window.

The best solution is update to Cubase 11.
