John,

I do have Amplitube 4 and all works perfectly in Cakewalk, and as Andrew's test showed, they work in BIAB with no white noise, just Real Band is the only issue. It has always been a problem with Real Band, nothing else.

Also, I guess Real Band does not recognize VST3, because when I click "edit VSTi" and go to folders, it will recognize a .dll but not a VST3.

Thanks!
