That's not how I see it. We did this as an experiment when I was teaching music technology. We tried this as a test. We did it with a piano and drums.we recorded the whole thing on piano and drums, complete with of course mistakes.we then replaced the piano with left hand and right hand recorded in different takes, and did kick and snare in one take, toms in the next and then hats and metal stuff. Looking at them on the screen, all the musicality had gone. The little pushes and pulls, the timing of the run downs through be toms ending on the kick were horrible, and the same thing on piano. The left hand and right hand kind of missed each other. The right hand became metronomic and always hit the beats where it didn't when played with the left hand doing its bit. You end up with something that sounds quantised. You could have done better with a drum machine. It's an awful idea. It's also not the way drummers normally play, so they won't play as well.
