Sonar crashes when automating VST3 plugins

[MIDInco]

Hi everyone, I'm encountering an issue with Sonar crashing when automating VST3 plugins, and I'm looking for some advice or solutions.

Issue: The same plugin works fine with its VST2 version, but when I try to automate the VST3 version, Sonar crashes.

Plugins tested: I noticed this with Serum, but similar behavior occurs with other synthesizers like Sylenth1 and some effect plugins.

Attachments: I've included a video demonstrating the issue and a project file that reproduces the crash.

If anyone has experienced a similar issue or knows of a solution, I’d appreciate your input!

Thanks! I've reported it to the developers who will be looking into it.

Haben Sie versucht, das Serum nicht als einfache Instrumentenspur, sondern als MIDI-Quelle (im Synthesizer-Rack) zu laden?

I have not tried that yet.
I will test it when I have time.

I have downloaded your project and tested it.
I cannot reproduce the bug.
Automation works correctly in the VST3 version of serum.

Regards.

Thank you for verifying.
A Japanese friend was able to reproduce this bug, so it might be a language-related issue.
