Ardour don't see synthesizers on Fedora 33

Hi Ardour community. I’m on Fedora 33 on GNOME. I have a problem with virtual synthesizers. Ardour don’t see them and I don’t know what to do with it. I installed Ardour from application center of Fedora because can’t install it via command dnf. Also can’t delete it via command yum.

Ardour can see only 2 plugins: helm and geon kick. I tried to install zynaddsubfx, odin2, bristol, amsynth but haven’t a result.

Can you help?

Those are standalone applications, not plugins that can be loaded in a DAW.

On GNU/Linux, Ardour 6 can load LV2, VSTi and VST3 instrument plugins.

Ok, but what I need to do with zyn-fusion and odin2?

were any of these packages you installed flatpack, snap or other sandbox type package? Seems to me fedora is real big on these things. If so file a bug against the package… Ardour, and audio plugins should not be sandbox packages… one sand box can’t see the next.

I kinda solve the problem via installing odin2 from official website and zynaddsubfx via command dnf install zynaddsubfx-lv2. In first time I have installed standalone zyn. But my zynaddsubfx now starts with gray window and that’s all. And the window is like old zynaddsubfx UI design.

What I need to do to fix it and how I can download new UI design for zyn?

The zyn packaged with fedora is not build with the zyn fusion ui because of bundled libraries which is not allowed, see https://bugzilla.redhat.com/show_bug.cgi?id=1765546

Help would be needed to fix that, if anyone would like to volunteer time

Ok, but what I need to do with zyn that launching without any UI, just gray window? When I playing note he makes a sound and I can choose presets, but can’t change anything in it.

You can try Yoshimi

It’s a fork of ZynAddSubFX

It’s working. Thank you
