I have written many times on this forum for suggestions in the name of all users of the aero XDJ. Few have been listened to, but I have confidence for the future in your development team, because I I know that Pioneer is the top (as a support).
I use many months XDJ aero. But, unfortunately, that you believe it or not, I use it ONLY with the usb stick. You say: "it is a waste for this device!" is exact! it is a waste for this device (which is also really cost that much!, nearly 1000 Euros!)
So. (I know about 30 people who own XDJ aero). 50% use ONLY the usb key like me and 50% use XDJ Aero + Mac + Traktor fo Mac + Traktor X1 Controller. But ALL of the 30 people consider USELESS Recordbox at this version (only useful for making playlists for the USB keys, although even here there are problems, because Recordbox "cut", "blurs" the end of the song out of about 20 - 30 seconds).
Recordbox for mobile devices is a nice idea, but too limited! For example, you can not act on the song when it plays. It is limited to only take and put the song on XDJ aero. Everyone would like to be similar to Remotebox! (or compatible Remotebox) (but that I had already said).
I do not own a Mac, and I do not use Windows or a laptop for my evenings. I would use an iPad (even via wireless) to manage live the song that is playing! What chance do I have? If Pioneer continues not to be compatible remotebox for XDJ Aero, I'll have to look for other solutions. But what? I have no idea! Thought i use XDJ aero + iPad + Software Traktor for iOS + controller to Traktor for exemple Traktor X1 Controller. But do not think that's possible!
I hope you can give me ideas! And please, I know that my English is not perfect, but please pass this feedback to the development team!
I hope that XDJ Aero can evolve and be a product 360°!
I am always available to provide suggestions to the development team.
