GP4 crash on load when Korg Opsix VST is used


I had my first GP crash today. I have backspaces and a rig that has been working fine for a couple of weeks. Suddenly, it crashes when loading and is seems to be a problem with the Korg opsix VST3 module. If I change it to an audio unit version, it works (for now).

I have included the crash report.

Is that plugin supported under the os you are using?

Yes, according to the OS compatibility chart:

It’s the KORG Collection.

The crash is in your plugin as shown by the stack trace — you should report it to the developer of that plugin. See first bold line below

Yes, I thought so. Will try to report this to Korg.

Last month I posted in another thread:

I reported it to the developer, but they could not reproduce the crash. As a workaround I should use the AU-Version.

I hoped that the last Update has helped, obviously not, Korg Opsix is still buggy. That is very bad, Opsix sounds awesome.

The crash was in the GUI part of the plugin, this much I can tell from the stack trace.

I have also reported the issue to Korg. Let’s see what they say.
I replaced the VST3 version with the au one, and so far it works.

I also had problems with the Korg Arp Odyssey VST3, it didn’t crash, but midi events seems to get “stuck”. I have an Arturia KeyLab MkII, and when I move the mod wheel the notes get stuck. To make the keyboard work again, I have to unplug it and then plug it in again. If I change the plugin to au format, this doesn’t happen. Not sure if this is a problem with the Korg plugins or GP4, or a combination.
I have now switched all the Korg plugins that I use to au.

Off topic: Tomorrow Arturia will release the Arturia_V_Collection 9!

But back to Korg Opsix:
I did exactly the opposite and have changed all AUs to VST3 where possible. I do not trust AUs. In my GigFile I now have three or four AUs and I hope, that there will be a VST-Version for Apple M1 soon.

From Korg I use only the M1 VST, I had replaced a lot of Triton Sounds and until now I haven’t tried the Opsix again. I wait for the next update.

Funny! Well, maybe I will run non-Korg plugins as VST3, and Korg plugins as au.
