Oliver, like most V3 vocaloids, just comes on his own as a lite version.

You buy the V3 engine separately, or with a vocal purchase (which is cheaper).

Piapro studio, is as the others stated, a Cryton bonus.

If you own a good DAW like Cubase, the full V3 engine, you've got everything you need for Vocaloid making.

It saves buying a decent DAW and the full engine if you don't have those, but like a lot of substitute software doesn't do quite as well as those its replacing. IT has some unique features though (like phonetic manipulation) and honestly isn't something to turn down if its there to be used. :-/
