I do MIDI drums, triggering samples, and I program most of the drums manually in PT. Then I add "flaws" and vary the velocities so it sounds more like a real drummer. Occasionally, for tricky parts, I use my , through my . I don't use the sounds in the D4 at all. Kind of an old set-up, but it works for me. I also have the trigger inputs of the D4 patched into a patch bay, so I can use any source to trigger samples.
