Hello,
When I plug a midi device (after opening of Cubase) during a session this provoke lag and (long) momentary freeze of Cubase , that was not the case with Cubase v11.
Example with my Qcon Pro G2 or my Akai mini MPK I

Hi,

Do you use MIDI Remote script for any of these devices? Do you use any custom-script?

Are you on Mac or Windows?

MIDI remote only for the Akai, no custom-script, I’m on Windows 11 pro

the freeze is very long for the Icon Qcon Pro G2 for Akai it seems to be maybe ‘normal’ to refresh the midi list if a device is hot plugged.

Hi,

Do you have setup Qcon as Mackie Remote?

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.

Sorry for the delay I had some impediments (covid … etc …) , here the dump (when I ran the procdump command Cubase crashed). I launched Cubase and after I plug ‘on’ my Qcon Pro G2 controller, so Cubase freeze and lag I ran the procdump and cubase crashed (ha it’s normal with the command -t I guess) :
