Adding midimap from mac to ipad?

Is it possible to use midimap learn on a mac for a non natively supported controller and then export it to a jailbroken ipad?

Please note that djay is only supported on official iOS versions. 

I bought djay and djay2 for ipad. I am just trying to add more functionality to it by connectiong my non supported midi controller. I haven’t jailbroken my ipad yet but I am pretty sure that you can still buy and install apps from appstore on a jailbroken device. Not sure what you mean by “Please note that djay is only supported on official iOS versions.” Would my Djay 2 app stop working?
