"Fortunately, thanks to some clever reverse-engineering from Javier Serrano Polo's VeSTige project, Ardour3 and QTractor can be compiled with support for native Windows VSTs, and LMMS includes a module that provides a VeSTige-based VST-to-Linux bridge."
Afaik Ardour3, Qtractor and LMMS, when compiled with the VeSTige headers (or with the original Steinberg VST headers), can host native Linux VST plug-ins, so no native Windows VST's.
