I compiled Ardour2.1 with vst support. Program flags a lot of missing ladspa_descriptors. This used to floor Muse when I could run that at all. Program finds all the vsts through a symlink on my home to the windows vsts. It thin polls them. One with "registrations" do not find them. Wine fails and so does Ardour. It might be a better idea for these programs to "test" a plugin if and only if I try to use it. And then, fail gracefully. I'll try a non-vst ardour and see if it gets past the ladspas.
