Cubase 10.5 totally fails running with Melodyne 5

Hello everyone!

So I decided to try out Melodyne 5 in a “larger” project (7 minutes, 100 Tracks, mainly Mono Audio), and after a while, things got slow. Selecting an event in a track, in which Melodyne was used (via ARA), took several seconds, but after working on more stuff, even opening a Cubase menu (or doing any action) makes Cubase freeze for around 20-30 seconds.

When selecting an event edited with Melodyne, Cubase runs smoothly, but as soon another event get’s selected, everything freezes. I have a feeling, this has to do with VariAudio Edits beeing active all over the place.

Has anyone similar issues?
I run Cubase 10.5 with Melodyne 5 on Windows 10 (Ryzen 5 3600, 32GB RAM).

Thank you in advance!

Edit: I want to note, that rendering all the events, solves the issue, but this seems to be a severe problem of the software.


Do you use VariAudio nad Melodyne at the same time?

Could you please generate a DMP file and share it via Dropbox or similar service?

Please use Microsoft ProcDump utility to generate a DMP file.

  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<username>\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 10:
    procdump64 -e -h -t Cubase10

Nuendo 10:
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.

Share the DMP file via Dropbox or similar service, please.
