User blog comment:Amythiststar/What is the difference between VOCALOID Editor and VOCALOID Editor for Cubase?/@comment-53539-20141206195611

One is built to work (hopefully) flawlessly inside of Cubase, allowing use of all the tools Cubase uses. The other is just a normal stand alone program. If you need a DAW and happen to own Cubase, its ideal, but I couldn't telly you anything else.

Basically, other DAWs like FL loops aren't 100% certain to work with the software. :-/
