In terms of their support : it seems there is NONE ...

Requests are NEVER replied to, messenger inquiries on FB are utterly ignored.

Bought vocalizer pro but it crashes the daw and it is a reproducable bug too. My request to them has never even been answered, so now I have bought a plugin from them that doesn't even work properly and all level of support simply lacks so I'm getting 'no help' whatsoever from them.

Good going Sonivox ! Very professional .
