First of all, using styles or midis does not necessarily free you to do nothing. I'm getting to be an exclusive midi performer, but I am still playing all out with every (well almost every) song. My concept of using midis is to give me the band members I don't have, so I need the drummer, percussion, bass player and sometimes strings or horns. I have a great guitarist who is able to play rhythm or lead as the midi requires. My sax player is useless anymore, but he's a good buddy (know what I mean. I'm doing 75% of the work and getting 25% of the gig.
