you need to constraining application to the system iOS6??!
I have a Numark iDJ Live (first version) and with the system iOS6 there is some problem of recognition.
the new version djay2 can not make it available to ios5 +, or some specifications of the new version are not available for the older operating system
djay 2 only works on an iPad 2 or better.
