Yes, all of the above.

With the RealCharts, the piano ones are from the Yamaha acoustic/digital so you get the actual playing.
I remember saying years ago to have midi pickups on the other instruments like Drums, Bass, Guitars etc.. to give the actual playing in the midi.
As it is now with the Guitar RealCharts it's using Control 85 to represent the articulations in the notation.
I remember suggesting way back an option to convert the control messages to actual midi articulations, but thinking about it now I can do that in Reaper with a script, though having it for Biab user would be better.
You have UJAM virtual instruments now that follow Studio One chord track, Toontrack may go that way also (hopefully the BBPlugin will have that soon).
Yes, it used to be "Look Ma No MIDI" now MidiSuperTracks, so how about some guitars, flutes, sax and anything else with a midi pickup.
