I would advise you to get in direct contact with Serato ... I have no doubts they know you well ;) If you are willing to develop new inovative video options and possibilities for Itch or Traktor, you can boost your business even further more. And I think it can also serve for Native instrument or Serato. You have nothing to loose if you try to speak with them; Have you seen the latest threads about mixing sound and video on the DJ or VJ forum? I've been VJ -ing since 20 years and DJ-ing since 10 years, so I've got a lot of experience in both domains and I'm keen to continue going even further; if you would like to speak about the future of DVJing technology, I'm more than happy to exchange and share my ideas with you, as we both seem to have the same passion for it.
