If he's referring to V-Vocal, you can still use it in Platinum.
Upon re-reading the OP I'm not sure what exactly is desired by "pitch shifting without changing notes"...by definition, a shift in pitch will change the note. Maybe he means a change in timbre. The Melodyne version that ships with SONAR will do that because it won't compensate for timbral changes.
Then again for my last song where I needed a female vocal, I had a female sing the vocal. Sounded just like a female singing a vocal
