Clear Undo History?

I clear my Undo History all the time on Logic , to keep project size down , should or do we need to do this in cubase. >??

The Undo History isn’t saved with the project. It’s tied to your current Cubase session.

Once you finish a project, you can use Back up Project to remove unused audio.

Ok but what about undo history , of say Midi editing or changes in a project , not audio recording ? just wondered if the undo history make the project larger and maybe slower over time ?

Like I said, the Undo History isn’t saved with the project.

ok thanks . so after closing a project Undo history is lost , and starts again when you open a new project ? Thx
