I've been using Vegas since it was an audio-only environment. I'm still happily using Vegas13 (on a Windows 10 system), and while I was enthused when Magix took over Vegas from Sony, I was scared off by lots of posts at the time about how Add-Ons & plug-ins acquired in the Sony era wouldn't work in Magix because of the specific product-name in the underlying scripts. I have a whole bunch of plugins I acquired during the Sony era... Most important are PluralEyes4, UltimateS Pro4, Vegasaur2.2 and Boris Graffiti 6.6. I also have several Newblue FX sets, and some sets from Pixelan. Is it still the case that those might not work in the Magix version(s) of Vegas?
