I have a workaround for multiple waveshells (sheltovst.exe) but it's far from perfect..For example, I just updated my Waves version 10 plugins and now VEP projects won't load certain waves plugins (a "waveshell 10.0" in the place of the plugin name, in this cas Abbey Road Chamers). Please make VEP see multiple Waves waseshells!
Not to mention VST3...
