I thought about it and figured it was better to do the switch now.
After I updated to unified and also included vst plugins, Ardour finds Lv2 one’s, but it’s VST search path is still /app/extentions/VstPlugins/lxvst. Adding path manually does the trick.
Lmms (carla) cannot see either. UPD.: Adding additional plugin paths in Carla settings manually fixes that.
In Ardour I had to reset the path for the VST (LV2 is fine).
Same in Carla I think.
Ah, so fresh installations of those apps should be OK by default. Also, tested resetting in carla - works.
yes.
Also, Muse3 is a bit more fiddly.
You notice that in Ardour it’s only VST. LV2 or LADSPA don’t have that problem.
Ardour probably just honours environment variables for ladspa and lv2, that’s why those work. Carla has paths set in some config - hence everything needs to be reset.
Anyway, seems that I have some occasional Ardour crashes while using plugin, probably need to test/investigate it a bit more before submitting.
Sometime plugins crash and bring the app down.
However I sent you a pull request to address a few things including statically linking which is the recommended way for plugins.
Thanks for the PR, merged!. One thing I am still trying to figure out is how to load banks in plugin’s browser. Created issue: https://github.com/takuvata/org.freedesktop.LinuxAudio.Plugins.ZynFusion/issues/2

Scratch the above, I just had ~/.zynaddsubfxXML.cfg and ~/.zynaddsubfx-bank-cache.xml from regular install that was messing things up. Compile option actually works.
Created a PR to flathub.
I also created a git repo for Calf Studio Gear plugins. Just could not figure out how to link fluidsynth2 statically. Help would be appreciated 
there is fluidsynth2-static.json.
But Calf, which I have here, has a serious issue that makes me a little bit worried about: gtk2 is required and that’s bound to be a nightmare.
Same problem with Gtk2 happen with Invada lv2, amsynth.
I see. Shame - really good plugins. It can be built without GTK, so no custom GUI, but obviously that’s not great for usability.
Maybe I should do that (there are already packaged here).
I was holding back a bit, I have a few I need to submit. Yoshimi also has another issue is that the lv2 plugin requires jack, and that’s a bit of a no no.
This is my calf “branch”

Also the upstream issue for Calf

The comment by someone being Gtk isn’t a good idea, and then they mention CTK which is their toolkit, as work in progress.
hi @hub !
I went to re-install Purr Data from flathub today, and I got this:
$ flatpak install flathub net.purrdata.PurrData
Looking for matches…

Proceed with these changes to the system installation? [Y/n]: n
I didn’t want to install every LV2 & LADSPA plugin available, so I had to rerun with --no-related. I feel like for Purr Data we should avoid installing these by default – is that possible?
This is a problem I have discovered very recently. It doesn’t happen with any of the other apps, just Purr. And I have no idea why.
I originally couldn’t even figure out how to track “dependencies” and discovered it was Purr by a random coincidence.
Nevermind I think I have found why… PR to come in a few minutes.
For the record
