After awhile, Cubase 11 crashes when loading Altiverb 7, doesn't crash after computer restart

I seem to be having a weird anomaly with Cubase 11 and mainly Altiverb 7. Using Windows 10.

After running Cubase for a few hours, and when I try to load an instance of Altiverb 7 in a dense project, Cubase hangs.

I’ll then have to restart the computer, and open a fresh Cubase, load Altiverb, and this time, it doesn’t hang.

But again, after a few hours, when I try the same thing, Cubase hangs. Tends to happen with Nuendo with certain plugins as well.

Any ideas would be much appreciated. Thanks.


You can try to use Microsoft ProcDump utility, if this will generate a DMP file.

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.

Okay, give me a few hours to let Cubase/Nuendo stay open, I’ll then reproduce the anomaly and try to get out a dump file. Thanks so much for responding.

Hi Martin, I tried the Task Manager to create a dump file, but it created a dump file of 7.9Gigs in size!
Is that normal??? Notepad, Wordpad and MS Word couldn’t even read the file because it’s too large!


ProcDump should make smaller file, because it prints just the memory of the frozen application. Task Manager prints the whole memory, therefore it’s so large.

Have you tried ProcDump, please?

I’ve followed your instructions, let ProcDump running and waiting for Nuendo to hang.
But how does it work exactly? Because I don’t see any dump files being created by ProcDump?


Sorry, I’m not Windows user, I have never used it. But I believe ProcDump would make the dmp file in the folder, you specify, once the application hangs.

Hi Martin, here’s a link to the dump file.


Do let me know if you have problems opening the file, my notepad seems to have a problem doing so. Thanks.


Thank you. I will work on it tomorrow.

Notepad is not the right tool to work with dmp files. :wink:

Ah I see. Okay great, thanks so much man!

I ProcDumped another dump file, this time Nuendo really hung for a good 10 minutes. Hopefully this dump file will help as well.

Dump File 11-1



To be honest, I’m not 100% sure, but to me, it looks like the issue is on Altiverb side. Could you please get in contact with the plug-in developer?

Hi Martin,

thanks for your input. I was with an Altiverb representative and he basically said he has no idea as well.

But you’re right, I have a feeling it’s on the Altiverb side, because after many sifting through forums of my related problem, it seems Altiverb is known for causing alot of crashes on Steinberg.

Someone even complained that Audio Ease spends way too much time recording reverbs, and not enough paying attention to making their plugin programming more solid.

This is really a shame, because their stuff is really good. They’re like a plugin company with a weak bridge that leads to treasure. Unfortunately, they do seem to spend more time building their treasures and not enough time making a decent bridge that leads to of all things…their treasure.
