Sometimes midi is all we have, not everyone can afford real instruments or the gear to record them if we do have them. For the first couple of years when I started writing again in 2004, all I had was an untunable electric guitar {a gift - probably homemade} that I had to press up against the wooden arm of a chair just so the sound would be amplified enough to hear the chords. Some of us are poor and although I now have a GNX3 for amplification {another gift} I still only have that untunable electric guitar to use.
