That's it. Each .csd file is basically a configuration preset for Cabbage. So each time you export a plugin, one of those dlls is copied, renamed and put into the same folder as your 'csd file. When it is called by a host it will read the compile Csound create a corresponding GUI. It's completely dynamic.
