Internal Ace LV2 Plugins

[sound8]

I apologize, hopefully this makes sense.

From what I understand LV2 GUIs are created separately from their corresponding LV2 plugins themselves. LV2 plugins themselves are said to have no GUI they use a generic GUI based on what audio applications provide (some form of knobs,faders, etc)

The internal Ace plugins are said to be LV2.
They appear to use the generic GUI but they also seem to sometimes include graphical elements as well, for example the EQ and Compressor.

So I was wondering,
Do these Ace plugins contain a GUI that just looks like/uses some generic elements.
OR
Does LV2 plugin language allow for these graphical additions without the need for an actual separate GUI.

Not Important:
Also never thought about/have no reason to do this but because the Ace plugins are LV2 can they be used in other audio applications that support LV2 or are they specifically tied to Ardour in some way?

Again hopefully this makes sense.
Thank You

If you download the official Ardour binary from this site you get the option of enabling the nice ACE GUI that Harrison Mixbus has provided.

If you compile Ardour yourself or get it from your distro you get only the generic one.

You can get the GUI for your non-official binary by following my and/or Robin’s comments here

ACE plugin GUI how to change [solved]

Go to tools/linux_packaging and run ./build --public to create an Ardour bundle including the Harrison ACE GUIs. If you haven’t run ./waf configure && ./waf build prior it’ll complain a lot about stuff missing but once it’s finished you’ll end up with a harrison_lv2s-n.linux64.zip that you can unzip to <path-to-your-ardour-install>/lib/ardour7/LV2/

Thank you for responding but I do not think it pertains to what I had mentioned.
To what you said, Ardour also allows users to opt out of installing the Harrison Mixbus GUIs during installation if desired.
Regardless what I was mentioning was how is it that ACE plugins using the “generic” (no GUI) still can show graphical elements in them, such as the ACE EQ & Compressor, they have graphical elements and generic faders in the same plugin. I didn’t think LV2 would be able to do this without having to create separate GUI wrappers for them, exactly what Harrison Mixbus plugins are doing.
Thank You
If anyone has any answers to my original post questions above, please let me know.

The graphical elements are provided by Ardour rather than the plugin when you use the generic controls.

It’s possible to develop multiple UIs for the same LV2 plugin. Unless I’m horribly mistaken, MOD multi-fx boxes have their own UIs for pre-existing LV2 plugins.

These GUI’s were built by Harrison for the existing ACE LV2 plugins. I do not think the source code is available.

LV2 allows a GUI to be built seperatley from the plug itself. You could build UI’s for existing LV2 plugins if you want to.

I think the GUI is always seperate from the plugin dsp in LV2. I may be mistaken.
