Although you think this is the correct route. My opinion woud be to talk maybe Facebook or somehow get a hold of Ean Golden on how to go about this. He and his staff over at djtechtools.com do a lot of how to's and have helpful advice as far as controllers go they build and market there own. I just think they have a more direct connection to djs and this.
They may be able and willing to tell you how to go about this.
Dont get me wrong NI does have and is very innovative with controllers. But djtt has a good relationship with NI and more of a link to the litttle guy.
My opinion of course. someone else may have better advice.
Be careful someone will try to take it for their own good or bad idea. there are a lot of leeches in this pond called earth.
