Re: Fedora and LV2

ok. with the 'qt5-qtstyleplugins' package installed and environment settings

as below, RG now runs with lilv and gtk2 but I don't seem to have access 
to any lv2 plugins.

I have a variety of lv2 plugins installed but the dialogue only shows ladspa

and dssi architectures and only ladspa plugins, of which I have a couple.

Chuck.
