Crash when recording into Score Editor

Cubase
1

Can someone please help me and tell me what I’m doing wrong.

I was all excited to get 14.0.20 for my new MPB as I have an instant crash issue with the Score Editor in 14.0.10 (no problem on my Windows 11 system)

But it’s still there even after this update.

Problem.

If I make a MIDI region open it with the Score Editor and record directly into it with my MIDI keyboard using a VI to watch the notes appear as I play them then …

Poof - Cubase just crashes instant quit out and vanishes!!

It doesn’t do this on Windows 11.

I’m on OSX 15.3.1

Is there something I’m doing wrong?

Any help would be greatly appreciated.

When you say that you are recording MIDI, do you mean in step time input or hitting the record button? Does this happen if you create a new project and use a standard Steinberg VI such as Halion Sonic? Or does it only happen in a specific project?

Could you please attach the crash dump (*.ips)?

This log was created playing EZ Bass into the Score Editor live.

Hi Paul,

Yes it happens even with a Halionsonic instrument.

I record (after pressing record) a few bars live with my midi keyboard into a brand new project

Stop and open that region with The Score Editor.

Then continue recording MIDI notes in real time live into The Score Editor watching the notes appear as I play live - all goes ok for about 15 seconds then … poof instant quit and Cubase vanishes!

It doesn’t do this on my 13900K Windows 11 system - everything is perfect.

Thank you for any help you can offer.

Here two more crash logs - both produced using Halion as an instrument played live MIDI into the Score Editor.

Thank you

Thanks for reporting. We’ve got some problems at the moment with our crash log analyser so I can’t see what’s happening yet.

I can see that the crash appears to be related to marker tracks. Do you have any active marker tracks in your project?

No marker tracks.

This test was done in a totally new blank project.

One single instrument track - nothing else in the project whatsoever.

Hi Paul,

In case it helps you, I tested Cubase 14.0.20 again today on my Windows 11 - Intel 13900K Scan 3XS Workstation and everything was perfect - no issues at all recording live MIDI into the score editor.

So for me this is an MBP M4 Max OSX 15 issue.

Thanks.

I’ve been unable to reproduce this on mac or windows, so I think it may depend on exactly the sequence of events and your MIDI recording mode settings (I’ve tried the regular and merge modes). Also you say that you see the notes as they appear, but that’s something that isn’t supported – the score update only happens after the recording is stopped (it needs to be that way because the algorithms need the context from the whole part). So I’m intrigued how you’ve got it to work that way.

Could you please record a video so we can see exactly what order you do things?

Hi Paul,

I will record a video.

I also own Dorico and I know Dorico can’t show notes appearing in real time.

It was a feature I enjoyed in Logic (which is designed to do this)

So I was thrilled to discover it works this way in Cubase 14 on my Windows 11 system - though now it appears not by design!

Video to follow.

I can follow this exact same procedure and it works perfectly on my Windows system.

I find as a composer it’s an extremely useful feature and I’d be thrilled if it could also work on OSX 15.

Thanks for the video – that really helped, and I was able to reproduce the crash on Windows too. It’s very timing-dependent so I think you’ve just been fortunate that it hasn’t crashed on Windows for you.

The reason I wasn’t able to reproduce it originally is that I always create a part on a new track and then record into it, which doesn’t trigger the bug. In your case you are just recording directly which is creating the part on the fly, and that was the key bit.

I can see why the crash is happening, but I’m not sure of the best fix yet (short summary: recording this way is changing the active parts on one thread, but another thread is happens to be reading the list at the same time and gets the rug torn out from under its feet).

The workaround for the moment I think is to make the part long enough before recording and use the Merge MIDI Recording Mode.

Hi Paul,

Thank you for the workaround suggestion and for taking the time to look into the issue - it’s greatly appreciated.
