Sync between midi/score editor when splitting, and staleness

philmac · February 3, 2026, 8:52am

CB 15.0.10 on Mac.

The syncing between midi and the new score editor has improved since it was first released. But with 15.0.10 I still see some fundamental issues, e.g. the Split tool.

Create a New Project
Open Score Editor
Create a Full Score Layout
Add some midi notes

Hit 3 and Split the midi

Delete one part

Score does not update

No indication of staleness (i.e. a tick instead of a square icon in Tracks)

Obviously closing the re-opening the window or switching layouts refreshes it but it’s not practical to keep doing that after every edit I make just in case.

It seems updating the score is semi-automatic at present but in that case we really need a “refresh score” button/keystroke or some way of knowing that we are looking at stale data (perhaps there is a workaround for this I could map to a key command?).

Also, if I export that to Dorico the stale version gets exported so I’m not really getting the true state of the underlying project which can lead to errors in scores.

Hi,

This use case works on my side (Cubase 15.0.10 on macOS).

Thanks for looking.

Are you on a Full Score layout?

I see it consistently in my projects and I can reproduce it every time with the steps above - I just confirmed that again.

Hi,

Yes, I’m in the Full View.

Attempting to upload a video here. So when you split and delete it would disappear for you automatically on the right hand side? I have to manually change layouts as I show here.

Hi,

I see you split it in the middle of the bar. In this case, I can replicate the issue too.

Ok thanks that is good you see it!

Note that in the first example I posted above with the screenshots, it was on a bar boundary (between bar 1 and 2) and still occured for me.

So it sounds like there may be some type of splitting operation that does update the score? It would be good to know under what conditions those are as it could be a potential workaround.

Thanks for the report Phil, and thanks Martin for looking at this in detail. As long as we’ve got clear repro steps, we should be able to get the Score Editor to refresh correctly. We certainly won’t be adding a “refresh score” button, as that shouldn’t be required once we fix this bug.
