The largest differences are:
Vocaloid Editor: A standalone program. The program cannot be opened in another program from my understanding, it can only be used on its own.
Vocaloid Editor for Cubase: The program can only open in Cubase software. From my understanding, the software should come with Cubase AI (
as noted here).
Another difference I noticed: "Real-time input of VOCALOID tracks by connecting an external MIDI device"
Vocaloid4 Editor does not support this, Vocaloid Editor for Cubase does.
(According to this chart).
I own Vocaloid Editor for Cubase and have not been able to open it outside of Cubase. All your settings and tweaks made in the Vocaloid Editor however is remembered and saved in the Cubase file.
You can use the
FAQ / Troubleshooting guide to see more information on these two.
Now, if this is regarding Vocaloid5, there are some major differences then.
Vocaloid5 Editor comes with Vocaloid Editor for Cubase 4.5.
Vocaloid Editor for Cubase 4.5 functions
very much like Vocaloid4 Editor for Cubase. However, it can read Vocaloid5 voicebanks and use these in the program. Cross-Synthesis can still be used in this editor, only if the voicebanks have the ability to do so.
In turn, Vocaloid5 can be used as a VST, so it should be able to open in other DAWs. It also has a ReWire function.
Hope this helps answer some questions. I'll let you know if I come across more differences between the two!
