The wrapper only produces a native-linux vst, reaper hosts
those vsts, so the 'multiple' part is handled by your chosen vst host.

LinVst can use it's linvstgtk3 app (from the 'convert' folder,
found in it's archive to wrap all the plugins in a given folder,
very handy to make a folder of your go-to plugins, and have them converted in
an instant, then add that folder to reaper vst path list.

Also, reading between the lines of their posts, I'll bet osxmidi and phantom-one
are both fine musicians, enjoying their their own code works
when playing
Cheers.
