It's not the drums, it's the drummer that matters. As a grad student, I helped out with a 2-week seminar in 1986, focusing on MIDI. Dave Garibaldi, Tower of Power drummer, taught a course on how to program drum machines from a drummer's point of view. He said a lot session drummers were starting to program drum machines. He acknowledged that there were still old-school guys whose physical and spiritual outlooks demanded drums, almost as if to test themselves everyday. It was a long time ago, so who knows how much I have edited and embellished this. But it is my honest recollection.
