7bit Midi NRPN messages to midi CC problem

hi, im trying to convert NRPN messages to midi CC from a sequential prophet x
but im really struggling with it. not sure how to go about it.
ive been down this road before with a novation a while ago and didnt get too far with it
but hopefully this will fare better
ive inlcuded the manual, the midi details are on page 78
if anyone can help it would really get me started, thanks Chris
