I'm only confused why anyone would want these translated via MIDI or anything else for that matter???
Because they're part of the guitar's articulation vocabulary.
Not that they'd make much sense all the time - but it also doesn't have to be the full enchilada. On a smaller scale, slurs and double bends are pretty much the same thing - and yes, in case it was possible, I defenitely wouldn't want these to be ported into the land of MIDI. I spent a great deal practising articulation on the guitar and don't want this to be lost. Which, fwiw (and as said before), is why I absolutely dig Roland's work on the VG and SY series - because these actually take guitar articulations into account.
And again and also as said: This is the fundamental difference between guitars and keyboards when used as MIDI controllers.
Pretty much anything you do on a keyboard (no, we don't need esoteric examples of people playing prepared pianos with spoons and what not) translates intp MIDI 1:1. Heck, even if you are a classically trained pianist, you don't need to adjust much (if any) of your core playing technique.
On the guitar however, not only are tons of informations lost, no, they're even causing unwanted side effects, so, as a result you have to adjust your playing technique quite a bit (or just get along with whatever it might be). In addition, the converter units are better off in case they're allowing for some pre-filtering before the signal hits your DAW or synth. There's "data thinning" options for a reason. I still remember the memory overloads on the Atari ST. Without careful playing and data thinning, you could simply run out of note/data memory back in the days. None of that would ever happen with a master keyboard.
