Cubase freezes while using 10%

What is happening with Steinberg Support? Do they still exist? I have submitted a new servere ticket more than one week ago. Since then, no response whatsoever. Since my upgrade to Cubase 12, I cannot use Cubase anymore. After startup it freezes while using 10% of my CPU, doing nothing.


Could you share the DMP file(s), please?

There are no .dmp files to find. How can I generate one?


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

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 12:
    procdump64 -e -h -t Cubase12

Nuendo 12:
procdump64 -e -h -t Nuendo12

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.

Thank you, Martin !
I’m running my Cubase an IMac, how do I do this on a MacOS (latest version)?


On Mac you can find the crash/ips files in macOS Console utility.

Don’t find anything related to Cubase in the ips files.
It doesn’t crash, it just hangs and have to force quit it.
