Multiple Versions of Ardour

I am using Ubuntu Studio 24.04 which includes an older version of Ardour. I just did the subscription thing, and want to install the current version.

So, do I need to uninstall the older version first?
Will the instruments and plugins that came with the older version still be available?
How should I proceed?

Thank you for your help.

If you get the official version from here it installs in /opt/Ardour-8.12, so it won’t interfere with the one Ubuntu Studio supposedly has installed in /usr
You can use both versions if you want or need to.

If your plugins depend on GTK, like the Calf ones, they won’t work in the official Ardour version.
So if you find any plugins that don’t work in the new version you 'll have to keep using Ubuntu Studio’s Ardour version for those sessions, or replace those plugins with a different version.

Thank you. That was informative.

You mentioned plugins that use GTK won’t work. I don’t know how to tell, but I am having a problem with a carla plugin.

When I load one of my previous sessions I’m getting this error:

2025-04-20T11:39:22 [ERROR]: LV2: Failed to instantiate plugin http://kxstudio.sf.net/carla/plugins/midichannelize
2025-04-20T11:39:22 [ERROR]: Found a reference to a plugin (“http://kxstudio.sf.net/carla/plugins/midichannelize”) that is unknown.

When I load this session in the previous (included in Ubuntu studio) version (8.4.0~ds1-2ubuntu8) there is no problem and the plugin works as expected.

Does lv2ls | grep midichannelize show the plugin URL? Does /usr/lib/lv2/carla.lv2/midichannelize.ttl exist?

AFAIK, the Carla MIDI plugins do not use GTK, they don’t have a custom GUI at all.
