Hallo!
One thought I've had, was asking authors of fine
free VST Plugins to port
their effects and/or synths natively to LV2. - But I guess one the first
questions wich come out of the box will be "which gui toolkit can I use for
it?" right after they figured out how jack, jack-midi and alsa midi
works.....
For me the GUI sounds also like a quite annoying problem - wouldn't it
be possible to limit LV2 to one GUI toolkit and then use this for all
applications regardless with which toolkit they are written ?
(E.g. in a separate thread or process - then it would be also possible
to use any toolkit you like in the plugin and it is simply started in
the host ...)
Otherwise I don't see much sense in writing LV2 GUIs ATM and using them
in non-GTK applications ...
