Well said,Tony
I would like to add that,for the purist's edification,playing midis does not mean all the time,and, it does not mean turning on the midi and pretending to play.

I use them when the style is custom made for the song,and much more identifiable than a generic style. Furthermore, I tweek the instruments,and mute parts so I am playing the melody and,manytimes,embellishing with my left hand.

From a musicians point of view,I think midis can be abused,but they certainly have a place in today's entertainment.
