Re: Hardware programmer for DX7/TX7

As well as MIDI CCs, it would be a good idea to support NRPNs, and maybe RPNS.

I can think of two synths I own that rely heavily on NRPNs, for external control / patch editing - the DSI Mopho Desktop, and the Bass Station II.

On both, CCs only allow you to change a small subset of the parameters.

Although CCs are 14 bit, it's probably acceptable to treat MSB and LSB as two separate 7 bit numbers, if that makes things easier, and it seems fairly common to use an NRPN to just represent a 7 bit value - but it could be either as the MSB or the LSB, depending on the manufacturer, or maybe even the particular model of synth.
