Savant Elephant's song on Massive.

[NoKare]

Hi everyone I recently heard a song made by the Norvegian producer Aleksander Vinter known as Savant, and I would like to know if you have any clue to make this kind of elephant sound
I know he made this sound in Massive ( check for his UKF Music Maker video ), I tried to do it, but can't get something even close to this :/

Thanks !

Envelopes controlling the pitch on a growl? (+ reverb etc.)
