Alternative to EQ10Q plugin?

Every since I installed the latest version of Ardour, I have not been able to use
the plugins EQ10Q and CS10Q. They were the best to use, but its tiresome to have them
fail every time I install a new version of Ardour.

I get this error message when trying to load them:
2025-01-10T08:06:55 [ERROR]: failed to instantiate LV2 GUI

Are there any good free EQ and compressor alternatives for these plugins?

ZL Equalizer and of course, LSP Eq

I have a plugin I tend to default to which is modeled on old analog consoles, with just high shelf, low shelf, and sweepable mids. My thinking was that with limited controls it is fast to just adjust and go and not get bogged down trying to optimize too much with a fully parametric EQ.
But after trying for quite a while and not getting the sound I was looking for, I put in x42 Equalizer instead, and in less than minute had what I wanted.
It is making me rethink my slavish devotion to emulating 40 year old analog practices.

If you need an eq, I would recommend the x-42 eq. The lsp parametric eq is also a high-quality equalizer.
If you need a dynamic eq , i would recommend the zl-eq

Ardour comes with the ACE EQ and compressor, which will always be available in future versions of Ardour. The prior suggestions are all good ones. Adding to the list, there is the plugin suite from Zam Audio. I think its developer was involved in the creation of some of the ACE plugins, but don’t quote me on that.

Heh of course I missed the obvious, good call on the ACE plugin, and yes Damien helped with several of the ACE plugins. I don’t remember the exact breakdown.
