update 9.5.4

hey after install the last update cubase start crash and media bay having some problem :open_mouth:


There is a long thread about 3 major Cubase 9.5.40 issues:

  1. Crash while record in some special cases.
  2. MediaBay preview out of sync and not possible to go thru the list while playback in Cycle and Align to Beats is enabled.
  3. Channel Strip Presets cannot be loaded.

Do you have a crash in other situation? If yes, can you share it, please?

Do you have other problem with MediaBay?

hey i head some crash in the middle of choosing audio sample its like freezing and crash

Share the crash dump file, please.

The MediaBay issue will solved in the next update, which will be released within the next week, as it was announced in the other main thread.

I will have a look tomorrow.

What did you do? What were the last steps?

Nothing out of the ordinary. I was trying out my new Helix. Running it into my Apollo. I always track via the Apollo. It’s a Twin USB.

I had just done a few takes when I armed a track to do another and it just crashed very quickly. Usually my crashes (very few) are involved with a freeze, then it disappears.

I had been thinking when I updated I was lucky enough not to have any issues.

Hopefully you can make some sense of this.

Thanks for taking a look Martin,


Thank you for the detailed info.

I will resolve the crash tomorrow (I don’t have the needed tool right now).

I would guess, this is the already known issue of Cubase 9.5.40, Cubase sometimes crashes while Record. It should be related to the 64-bit float Profess Precision only. Steinberg is going to release hot-fix within the next week. This issue will be fixed there.

Once I will resolve the crash dump, I can say, if it was exactly this crash or not. I will come back to you.


This is the known crash for CUbase 9.5.40. Because of this crash, there is hotfix of C9.5.40 planned for this week. Please update, once the hotix is out.


I can see 3 different crash sources:

  1. Serum_x64 (plug-in?)
  2. AudioBlockAccessStream > ntdll!RtlEnterCriticalSection: should be fixed by installing the latest WIndows update.
  3. NI Massive > VCRUNTIME140! > KERNELBASE: Plug-in or Windows issue.

I have searched every way I know how but cannot find Serum. I do remember downloading a synth as part of a deal to get Ozone 8 at a discount. I cannot find it anywhere though.

Sadly I’m on Windows Insider (since canceled).

I will keep a log on my issues, but this is a random issue for me at this point.

Thanks for the insight Martin,


Serum 64 bit :+1:

Cubase Pro 9.5.40 crashes on spectral analysis. Does anybody else has this bug? Cheers


It doesn’t crash to me here.

Could you share the crash dump, please?

Hi Martin!
Here are my crash dumps.
All the best
