I would hope that MIDI CC's NRPNs etc. are relected in GMPI as real valued
controls.

Why? The things being represented (value of a MIDI controller) are truly, madly, deeply, not to mention naturally integers.

MIDI control events is one layer, DSP math parameters is another layer. Let the plug map MIDI controllers to a real-typed control if it wants, but the nature of MIDI controller values per se -is- integers. (OK, bool in some cases.) So it's premature to represent MIDI CC values as reals at the event level, and introduces the possibility of nonsensical CC values, i.e. anything where the fractional part is anything other than 0. What if the graph routes that nonsensical 100.5 "MIDI real" signal out to a MIDI HW interface? What should the conversion be?
