[BUG] Cubase 15.0.21 Score Editor display not updating when notes drawn in or edited

Hello. I am wondering if this is expected behaviour. (MacOS Sequoia 15.7.4)

I have the Score Editor open in a separate window. If I make an edit to a note, say the pitch, in the Key Editor, the note doesn’t update in the Score Editor until I manually change the view in the Score Editor, for eg. selecting a different view or visibility option.

The same happens if I select a note in the Score Editor and change its pitch via the Status Line. It doesn’t update visually until I change the view.

Thanks,

To recreate:

  • Create a new project
  • Create a new MIDI or Instrument track
  • Open Score editor in window
  • Use Draw Tool to create notes, or insert/edit notes via Key Editor, record, etc.
  • The Score Editor view does not update until a new view is selected

EDIT: I have ‘Sync Layout’ active in the Score Editor.

EDIT 2: It also doesn’t show new notes being drawn directly in the Score Editor with the Draw Tool until the view is refreshed. Seems more like a bug.

EDIT 3: As far as I can tell the Score Editor display doesn’t update when notes are deleted or played in via step recording either.

EDIT 4: Additionally, Cubase just crashed instantly to desktop when I tried to record into the Score Editor via Step Recording. Something seems very broken with Score Editor. Crash log attached below.

Hi @inthevoid, sorry to hear you’re having problems. I’ve tried to follow the steps you describe, but I can’t reproduce any of the issues you are describing. Notes should always update immediately, and step recording also works without crashing for me.

Are you experiencing these problems with every new project? Have you been working successfully with 15.0.20?

Hi @StefanFuhrmann, thanks for your response. I’ve just tried trashing the preferences and opening a new project and it now works as expected. However the project that was having issues before still doesn’t work. I’ve attached a video above for reference in case it’s useful. I wasn’t having issues as far as I’m aware on 15.0.20, though I haven’t been using the score editor recently until this morning.

Hi. It sounds like you have one project that you can reproduce this problem. Is there any chance you can send it to us here? Thank you.

Hi @Akiko_Ogawa, yes I have a project that reliably reproduces the problem on my system - attached below. Thanks!

Thank you. This is very helpful. I can reproduce this in 15.0.20 build 226.

The same thing happens to me.
I’ve tested your file and I have the same problem.
Furthermore, if you tray to add lyrics text, You’ll not see the modifications in real time.
But if you exit from score and re-enter you’ll see that the changes are there.
This issue is happening on my orchestral projects, with instrumental and vocal tracks, created ante 15.0.21 (I don’t know if this happens in 15.0.20 because I didn’t work on them in those 3 weeks.

  • If I use on my secondary PC who has mounted 15.0.06, all is fine.
  • If I create a new project in 15.0.21, alla is fine.
    So I think that something has changed in last update.

I have sent a message with an example to mr. Stefan Fuhrmann, but this yours is a good file to test because it’s small.

Yes, your issue is the same as this one as the score editor is not updating in both projects. I find that if you open the projects that you and inthevoid have sent us in 15.0.20, it’s the same, so it’s not a new bug. I have logged this now. Thank you both for reporting this.

Hello!

Just to let you know that I’ve been having the same problem since this evening.

I had no issues until yesterday with a project I’ve been working on for over a month.

Suddenly, what I add to the score no longer updates.

The issue first occurred in Cubase 15.0.20 (Windows 11).

I updated tonight to 15.0.21 just in case: same issue.

I had to start from scratch and reimport everything to get it working again.

Any news about this issue?
For information, I’m working with W10 on both computers.
Thanks

Same with me. Win11 Cubase 15.0.21

Me too :face_with_bags_under_eyes:

Win11 - Cubase 15.0.21

I made a new project and imported all tracks from a rather big score with the update display problem.

All was well and this score updated properly. But when opening this new project again this morning the problem was back :woozy_face:

Reproduced here on C15.0.21 / Win 11.

Apparently it updates only when you close and reopen the score window.

Update: if you click away from the midi part in the project window and re select it, it will update.

As I said in another post, in an orchestral score it’s sufficient to change the instrument part to see the modifications.
But it’s annoying because it’s a blind work…

So can I - and I found the reason:

If either the tempo track, the marker track, the chord track or the signature track is locked it ruins the connection from the key editor to the score editor!

I’ve just tested these types of tracks, but it might apply to other kinds of track as well.

No wonder many people didn’t have trouble with this!

Thanks all for your feedback. We’re testing a fix internally and plan to make it available with the next maintenance release. Apologies for the inconvenience in the meantime. As Mads has found, this was indeed caused specifically by these types of locked tracks.
