Um, what?

I have an ipad app with rekordbox installed, my songs are within the application can insert the ipad in the USB port of XDJ-r1 and use these songs that are within the app ??
If not possible, the pioneer could release this function.

Yes you can connect the iPad via USB to an XDJ-R1 using the rekordbox app.

in XDJ-r1 of the screen shows the connected iPad via USB as non-compatible device

Marcio MB, you are right.
Sorry for some misleading messages.
XDJ-R1 does not support either rekordbox app for iOS or Android, but it supports remotebox, which can be used only with iOS devices.
Of course, you can use usual (non-mobile) rekordbox with XDJ-R1.

Yes, these names are similar and often mixed up but rekordbox and remotebox are totally different applications.
Thank you for your kind understanding.

Sorry! Dealing with so many products that sometimes trying to provide a quick answer I confuse the products and their compatibilities!
