Posted about this before, trying again to see if it gains some traction. Enabling both rhythmic notation and multi-rests on a score will crash the score editor with “Score Error 9,” and soon after crash the entire application if you try and open the score editor again. Happens in Cubase 10 and 11 over here, and two separate Windows machines.
To Reproduce-
Create empty project
Add a midi or instrument track
Create a midi region and open the score editor. Switch to page mode.
Select some bars in the score editor.
Scores → Rhythmic Notation → Show Rhythmic Notation
Open the score settings windows (Scores → Setings)
Select the layout tab, and change “multi-bar rests” to “1.” Apply, and score editor will crash.
Attempt to open the score editor again, and Cubase will possibly crash.
→ Result = crash
Yes, I can confirm the bug.
Cubase also crashed for me after doing all the points as described.
However, the crash only happend in page mode of the note editor.
Cubase could only be closed via the task manager.
