Just thought I'd mention to the list (as I only just noticed myself!) - a few months ago, Korg brought out a new version of the VSTi Polysix, making it 64 bit compatible for the first time. Details are on https://www.korguser.net/ I don't use the VSTi Korg all that often, but it any time I play with it, I always recognise the sorts of timbres it makes being very close to my real Polysix.
