The implementation could be a switch on the current NRPN. Nothing

also do an array of dynamically allocated function pointers
The upside is that we can actually have (and I do have) a physical
rotary knob that sets an oscillator to, say 440Hz. As for human
readability of the message, I couldn't care less since I am not going
to read the datastream aloud to myself anyway.
To get text representations of unique NPRN's for readability in your
sources, you would typically use something like:
-- myNRPN.h ---------------
#define NODE_NAME __LINE__
#define OSC_FREQ __LINE__
... which is of course an old-fashioned technique known since the
beginning of the UNIX epoch. But it still works as intended.

minor downside is that it sounds horrible and complicated and like
you've escaped to the 80's. Yay back to the future... You just can't
say in midi "set the sine osc to 440 hz." I.e you can say in your
message that you are setting a oscillator called something. You can in
osc, so much more human readable.
Yay! i want my whole app to communicate between
engine and gui via
midi! That's going to really be interesting... So what CC would i use
for add a new node named "node"? Sysex i guess? ....
CC 06 (Data Entry) would be a good candidate for entering text,
possibly with 96, 97 (data increment, decrement) to be used as a
cursor.
The backend will "know" that you are setting the text field of a node
because you immediately before have send a Non-Registered Pararameter
Number (CC 98 MSB, 99 LSB), setting the mode or destination to
whatever you have found reasonable to represent "node-name".
Problems: Attempts at midi-merge may fail. The data-entry slider cannot
be connected to two separate destinations simultaniously in any
meaningful way, other than that the last connection wins and all of the
data goes there.
