Cubase 10.5 freezes on first save (sometimes...)


Sometimes, after I create a project from a template, Cubase freezes as soon as I save it. I can then create it again, and it saves fine… It’s only happening for projects that haven’t yet been saved once.

Very annoying since my template takes a bit of time to load.

Any idea?

Thanks in advance!




Are you on Mac or Windows, please?

Hi Martin,

Thank you for the reply. I’m on Mac Os Catalina 10.15.3. My Cubase is 10.5.20.

Hi… I experience this on Windows 10 Cubase 11 as well. The first save takes about 5 seconds and every save thereafter is near real time.


Does it freeze forever, or does it just take longer, please?


Could you try to generate a DMP file, ZIP it and share a link, please?

Generate a DMP file and share it via Dropbox or similar service, please.

Once Cubase becomes frozen, open the Task Manager, right-click to Cubase and click to Generate DMP file.

If this doesn’t work, use Microsoft ProcDump utility to generate a DMP file, please.

  1. Please download ProcDump64 from Microsoft (~650kB) and extract the archive to a local folder on your harddisk.

  2. Run Command Prompt (cmd) as administrator (right click and select “run as administrator”)

  3. Navigate (in the Command Prompt) to the folder with the extracted procdump file.
    For example:
    cd C:\ Users \ \ Downloads \ Procdump
    Note: the dmp file will be written into that folder.

  4. Launch Cubase/Nuendo. You can work as usual. At any time, change to the command prompt and start procdump, to monitor Cubase/Nuendo for unexpected behavior (see next step).

  5. Launch procdump64 via Command Prompt:
    Cubase 11:
    procdump64 -e -h -t Cubase11

Nuendo 11:
procdump64 -e -h -t Nuendo10

The -h option will write a dmp file in case of an application hang. This might kick in too early sometimes, in case some action takes a little longer. Feel free to skip the “-h” option, if you are only up for fetching crashes.
The option -e will catch exeptions and the option -t terminations of the application.

  1. Prodump is now monitoring the Cubase/Nuendo process and will write a crash log, in case Cubase/Nuendo crashes or hangs. Perform the action that causes Cubase/Nuendo to crash and send us the generated crash dmp.

ZIP and share the DMP file via Dropbox or similar service, please.

Hi… I have created the zip file of the dmp file but it is 5gb in size and I do not have a file transfer service which permits files this large. Is there another method I can use to get you this zip file?



It freezes forever. Do you want me to send an DMP file as well?


Definitely, please. Do you have some *.crash files (on Mac)?

I’ll do that next time I’m at the studio, tomorrow.
