... the support guy also did not know what ARA integration was.
Well, I would chalk that up to the terminology. Their website doesn't mention "ARA", so if you had simply said "Melodyne", the light bulb probably would have clicked for him.
Then again, they only just added Melodyne in the most recent version, and there's little talk of it in their forums. I suspect all but the most basic Melodyne questions to support are referred to Celemony.
