@Dreamer: In this question I really can't agree. Do the examples of midi drum kits I posted above really sound too static or in any way artificial to you? And do you feel a recorded loop of a creative drummer really comes particularly close to a real live band? - As to my ears midi drums played on drum kits (which could be perfectly taken for midi styles if the samples are in the keyboard) are so realistic that I would never sacrifice the editing flexibility for audio loops.
And why do you characterize the wish to edit something as being a 'control freak'? Isn't it rather creativity to want to change things yourself rather than taking things the way the manufacturer prepared it?
