Problems with lv2 plugins on Ardour 7.3

[bengtfalke (Bengt)]

I have problems installing lv2 plugins and struggle to find why. I am using Ardour 7.3 (downloaded from ardour.org) on Linux Mint 21.1. Se Neofetch below.

I struggle for example with lv2 versions of Yoshimi and the Calf plugins

I put them in the .lv2 directory in my home directory let Ardour rescan the plugins. After that the show up in the plugin list but when I try to insert them on a track I get the following:

The log window shows:

Where did you get Yoshimi and Calf from; the Mint repository, self compiled or from their websites?
It could be a dynamic library mismatch.

Can you run the stand-alone yoshimi binary?

[bengtfalke (Bengt)]

I downloaded from their websites.
Yes, I can run the stand-alone version of Yoshimi.

Even the X42 plugins does not work for me… I find this so odd? Isnt it just about putting them in the correct directory? What am I missing?

[x42 (Robin Gareus)]

Do the “ACE” LV2 plugins that come with Ardour work? ACE-EQ, ACE-Delay.

Is there any further information printed, when you start Ardour7 from a Terminal Window?

Yes all the ACE plugins seems to work as well as your LXVST like X42 Parametric EQ.
How do I start Ardour from the terminal?

[x42 (Robin Gareus)]

@bengtfalke

as well as your LXVST like X42 Parametric EQ

I do not provide VST plugins. All x42-plugins are LV2.

@bengtfalke

How do I start Ardour from the terminal?

Type Ardour7 and press enter.

[bengtfalke (Bengt)]

The screen is from Ardour… showing a few X42 as VST or am I mistaken…

@bengtfalke

Are you mixing in some KXStudio stuff there? It looks like you’ve got that lv2tovst bridge thing in there muddying the water… ?

I’d be getting rid of that, Ardour supports both LV2 and VST2/3 and doesn’t need that bridge.

[bengtfalke (Bengt)]

Thank you , Glen! How do I remove that in a simple way?

[GMaq (Glen MacArthur)]

Hi, I don’t know the exact name… lv2vst…? If you look in your software center or Package Management you should have a Package named that or very close to it, you should just have to uninstall that. I don’t use KXStudio Repos so I don’t know if that is a separate Package or whether it is part of a meta-package.

This stuff should all just work… Linux Mint is a gorgeous Linux Desktop Distribution but unless you know what changes and modifications to make I don’t think it is ideal for content creation out of the box…

[bengtfalke (Bengt)]

Glen, do you think Ubuntu Studio is a better choice?

[GuntherT]

If I was a betting man, I would put my money on Glen recommending AVLinux over Ubuntu Studio.

[ardourwlk (M Aaronwalker)]

I was going to go with Cubase on a Vic20, but you may have some inside info.

@GuntherT

If I was a betting man, I would put my money on Glen recommending AVLinux over Ubuntu Studio.

Haha… not necessarily…

I obviously put a lot of effort and thought into AVL but I have no issue with UbStu even though they are significantly different under the hood… For someone who basically wants to run Ardour with the common best-known Linux Plugins and someone who might believe and take comfort in feeling that a bigger organization is better then I think Ubuntu Studio may be the best choice, especially to initially get acquainted. Some people find the sheer amount of options and extras and Plugins and Demos and Video tools to be overwhelming in AVL… Lol not everyone wants to edit samples with the File Manager…

[peter.zenk]

I use Ubuntu Studio together with Ardour (5/6/7) with almost no issues at all for years now.
Some folks seem to prefer AVL linux.
