Many thanks for your useful info. Ok, so it's my bad that i overlooked the fact that NB 3 Pro doen't contain a 64 bit version. Only the Server edition. To be honest, i find this ridiculous and i have never ever experienced a plugin company that doesn't provide a 64 bit version for specific version(s) of their plugin. I mean, normally, when a 64 bit version is made available by a company, it is available for all plugin versions, ofcourse, this is just my experience.
So i assume this means i have to upgrade to the Server edition to get the 64 bit VST I definetely don't want any bridged plugins in Cubase, bridging in Cubase is a cpu hog and unstable issue.
To be honest, i am starting to regret my Nebula 3 Pro buy. It says "Pro" but not even a provided 64bit version, making a difference with the Server edition ; doesn't sound "Pro" to me at all.
