NRPN control messages & Program Changes?

Hello, Brad! In this video (https://www.youtube.com/live/qzPySS8_CP0?si=r-Z1tOhb20rJ-NoJ) you said that “I control the synth by MIDI CC (so 127 step resolution) and it’s better to use hardware UI because of higher resolution (1027?).

So, here is the question - is that possible to add NRPN message support to the synth? It has a lot greater amount of depth to rid of the “steppy” control. Both modern DAWs (like ableton) and hardware sequencers (Hapax for example) can produce this type of controls, so it would be nice to have that opportunity.

I also wonder can I use PC for the separate voices in different configurations simultaneously (for example if I’ll have 4 parva voice cards, 2 of them for separate mono voices and 2 for single poly)
