Folks I’ve read the other posts about this topic, however having an older Ardour version I’m searching for any clue.
I’ve installed the Calf plugins from the repository. Not the crappy snap which doesn’t contain any, but from the Gnome software.
There is Calf plugin pack for Jack.
I’ve loaded the plugins within Ardour, but they don’t get load in the tracks.
It says this
Do you know if there is a way to make them work?
If you are running the LV2 format have you tried to install lv2-gtk-ui-bridge?
Look at this other post for more information
Most likely the version of GTK2 in your older 7.2.0 version of Ardour doesn’t match up with whatever version of GTK2 your Distro uses. In a case like this I don’t know if the solution posted above will help you, it is intended for keeping Calf working in Ardour versions newer than 8.4. In any case Ardour as-is doesn’t support Calf Plugins without external crutches so a better future plan is to replace them with properly supported Plugins (ie LSP, x42, ZL, etc…)
Also instead of that image service that spawns an annoying ad when I try to get a better look at your terminal output screenshot why not just use the built-in forum image uploader?
Great MI, it works. I’ve read that topic but I haven’t tried.
But is this problem connected to the latest Ardour versions or is because Ubuntu?
Anyway I will save the packages in case I have to install it again,
Ubuntu isn’t really relevant here… Plugin UI’s should NEVER use Desktop UI toolkits, that is the main problem.
Ardour versions prior to 8.4 had issues when Calf was built by the Distro with GTK2 that didn’t match what Ardour puts in their official bundles, in these cases often Ardour as packaged by the Distro would work because both Ardour and Calf were built with the same GTK2 development libraries by the Distribution.
After Ardour 8.4 Ardour forked and internalized GTK2 and made their own changes to it that retained the ability to build Ardour from source but it no longer was intended to remain the same as Distribution GTK2 versions so regardless of what the Distributions do when building Calf Plugins it will not match up with what Ardour has internally so that is why a 3rd party bridge is needed after version 8.4.
As far as I know that LV2 UI bridge also only works on systems using X11, if you or your Distro start using Wayland then the Calf Plugins will theoretically break again which is yet another reason to move on from them…
Thanks for the explanation Glenn, however that sounds Greek to me. I’m not that expert.
I don’t know if I have Wayland in Ubuntu 24.04 LTS, maybe pipewire?
Moving on from Calf stuff it’s not easy since they are really, really good, at least for me.
I should find something similar to stop using them. In my previous works basically I used Calf, Invada and some Guitarix plugin.
