Yes, its called ladspavst, and I get 1320 hits when searching for
"ladspavst" in google...
You probably won't get it to work though. It just worked with the
old vstserver which won't compile anymore. However, making the
ladspavst ladspa plugin work with fst or dssi-vst shouldn't be much
work, maybe an hour or something. I'm surprise no one has ported it
the last 6 years.
