I just installed Ardour 5.12.0 on Ubuntu 64bit. I’m installed few LV2 plugins and they work fine but the bundled ones are not working. When I select one and I click add, I get this message on the logs:
[ERROR]: LV2: Failed to instantiate plugin urn:ardour:a-comp
Same for all other ardour plugins. Others work fine.
I installed the other ones on $HOME/.lv2 but I do not know where the bundle ones are installed.
Do you have any ideas?
