Once a plugin fails to instantiate correctly it tends to get blacklisted and you have to clear the blacklist for Ardour to try again.
That being said, Vital is not statically linked, so it tries to use external libraries on your system that may or may not be the correct version for what you need to do. As a result that plugin just has issues on certain systems, and the author should and would need to statically link the plugin at compilation in order to avoid this.
I am also having this same issue with same error in Ardour 5.12. My OS is Ubuntu 20.04. I really want this fixed as Ardour is my main DAW. Well done btw Matt Tytel, great synth. .
I have the same issue with Ardour 6.9 Pop!_OS 21.04. When i try to assign a Vital instance to a midi track, Ardour shows me an error
2021-10-01T19:13:10 [ERROR]: LV2: Failed to instantiate plugin http://vital.audio
2021-10-01T19:13:10 [WARNING]: Failed to add Synth Plugin to newly created track.
II installed Vitalium and it works flawlessly in the Ardour session.
I installed Vital from the .deb downloaded from the official Vital site
The standalone version of Vital works fine.
Please tell me if a solution exist!
