Here's my opinion, for what it's worth. I play midi files in my act through my PSR2000, but remove all the keyboard parts so I can play them live myself. Doing this, I do not feel as if I'm selling out at all. In live situations, I find people are quite impressed with the fact that the song being played sounds "just like the original". Can't quite understand the fuss, but nevertheless, I find it to be the case in almost every live situation. Again, just my opinion...
