Bless be Carla, may many be its bridges and engine modularity.
Now that I know this works well - lv2 plugin host in another plugin - can use it for testing and fun stuff.
Need to think of the best workflow for such a tool, but cool that it is even possible.
Grab it at https://github.com/DISTRHO/Ildaeil if you want, dont forget to clone with submodules. No prebuilt binaries at this point, sorry, too early for that still.
Have a great day :)
