There's not yet a simple implementation of them on P3 because NRPNs are rather data hungry. You need to send controller 98 with the low order NRPN number, controller 99 with the high order NRPN number, then controller 6 with the high order value, and optionally controller 38 with the low order value. So you can send NRPNs already, but you need to dedicate 3 of the auxes in a pattern, but can only select 1 NRPN number to send a value to per step. A simplified implementation of NRPNs might over-ride some of the higher number MIDI CCs (say CCs 100 up) and allow a global map of those controller numbers to be sent as NRPNs instead. Storing the 2 bytes for NRPN number globally would then mean only 1 aux would be needed to send a (7-bit resolution) NRPN message, albeit to a limited pool of maybe 20 NRPNs. I don't have any equipment that uses NRPNs, so I'm not sure if that implementation would be much use. Would you need to cover a wider range of NRPN numbers ? Are low-order values commonly used ?
