Sadly, nothing exists for the controller, unless someone is holding out and not sharing. We are at the mercy of Algoriddim to make his happen Please upvote this thread if you have not already. FYI, I just tried plugging in the 707m. Nothing.
The same way Algorridim got Pioneer to do the CDJ, 400, & 200, they could sway Roland to make drivers for the iPad & map Djay AI if they really wanted too. Especially when Roland isn’t winning market share for Serato DJ. The Automix alone would win over most wedding DJs using the 707m. If VDJ can do it for the MAC, so can Algorridim. This is a no brainer.
The Zone Out feature of the 707m & this new Automix feature would basically guarantee DJAY AI dominate the wedding/mobile scene. Roland has no foothold on S****o, so they need to expand to other softwares to survive. Plus AI can play multiple streaming services. What a wasted innovation.
I also thought about this controller for a while, but then decided on a setup of small controller and external mixer, which is at least with regard to connectivity possibly more flexible. But of course it is also two individual devices, with all the advantages and disadvantages. And I think the jog wheels could be a bit bigger for a device in this price range. But with DVS you can perhaps compensate for that with the “only true jog wheels” …
But what is the current situation, is the DJ707m recognized by Djay Pro AI as a controller at all? Then you could make the effort to create your own mapping.
