The VST's are now "inside" Sonar, but they are still using the FXpansion wrapper on them (i can tell by opening the gui). it works, but its still not flawless. for example, it doesnt always know when a plugin should be a tempo plugin.
other than that the new 6.2 update is kinda slick, its got this new xray thing that makes plugins transparent. ACT is supposed to work better, although its also still not quite there yet.
friendly port naming is REALLY great. now instead of "RME Fireface 800 input 1-2" you can call it "FF800 Left1" or whatever you want.
highly recommended, still
heres the blurb about 6.2
