the wine approach wont help you. The idea behind that is to reuse the plugins
compiles on windows. It emulates the windows api as far as it needed and runs
the dlls. I do this for buzzmachine plugins for gstreamer, pitfdll does this for
windows codecs. If you do this for vst, you could use windows vft plugins under
linux, but only on x86 (and only on 32 bit for 32bit plugins).

If you want to run them on arm, then you need to recompile them. Using qemu
wouldn't give you the needed perormance.
