I have an Ardour session created with 5.12 some time ago. There were some updates of used plugins (in this case ZynAddSubFx to Zyn-Fusion) and therefore Ardour greys out the plugins and I have to replace them with Zyn-Fusion, where I loose the created Patches.
I had a brief look into the ardour session file where the settings are stored, but I have not found something obvious. So is there a way to get the Zyn Settings/Patches out of the Ardour session file? They must be stored somewhere to be reloaded on session start. Otherwise I need to recreate them, which will take quite some time.
