VST3 GUI actions have no effect

Installation & Configuration Linux
#1

Hello,
I’m fairly new to Ardour.
I’m trying to use a VST3 plugin (Roland D50), so I created a MIDI track associated to the instrument.
The audio is working, the GUI is also responsive (graphic elements do move, and so on),
however there’s no effect at all on the generated sound when moving the GUI knobs / switches, so it only sounds as in predefined patch.
I tried several plugins and noticed that some of them have this problem, but some not.

I tried the very same plugins (also same installation) on Carla, there they work as expected… strange.

What could I try to fix the problem?

Thanks
Andrea

Is there a free/libre plugin (source code available) that has this problem? That’d allow us to investigate.

Not that I’m aware of.

I tried the VST2 version, and it works.
It should be something related to VST3 support.

If you are using Yabridge to load the plugin in Ardour on Linux, it may be due to the version of Wine Staging in use. Yabridge recommends version 9.21 and notes on their GitHub page that there are GUI problems with version 9.22. Just a guess…
