You're probably right. I don't care for jigsaw puzzles, either.
I watched the Groove3 video on beat-slicing, and while it was impressive and creative in its own right, I kept thinking "sheesh, I'd have programmed the whole drum track by now".
Now, I'm not going to cop some smug "original creation" attitude - my bass and drum tracks aren't any more original than when the Beatles stole them from their predecessors in 1963. But my aim is to end up with something that pleases my ear, and the fastest, most direct route to that gratification is via fingers on keys and strings. As an added bonus, I can subsequently perform those things live without a computer.
Still, there was a time when I didn't associate record-making with MIDI, either.
