is the numark ns6 compatible with djay for ipad?

if not what are the highest end controllers that are compatible with DJAY for ipad?

No, i think the reloop beatpad(s). You can find this info easy on the djay website.

Hey Matthew, 

thank you very much for contacting us!

Unfortunately the NS6 isn’t compatible with our djay software. 

You can check out all the compatible controllers over here:

Have a nice week,
