True. That's one of the shortcomings I alluded too, but still it's possible to achieve fairly reasonable sound with MIDI of percussion, guitar, and even violin performance. I think the main reason other performers like it a lot less is that there's no way to digitally capture of their performance parameters. E.g., there are some guitar pickups with MIDI out, but that can't capture the techniques, even though MIDI could represent it (albeit in a non-standard fashion).
