controlling JX8P via JP8000

Hello,

has anyone tried controlling a JX8P using a JP8000?

I tried to control it with my Nord Lead, but sadly none of the parameters seems to be mapped in any way. Is there a chance that a JP8000 might "fit", because it's also from Roland? Of course there are programmers and programmable MIDI controllers, but I often thought about getting a JP8000 anyway, so this would be a nice side effect...
