I take the real drums file drop them into Ableton and then convert sections, usually 8 bars at a time, to MIDI. That way I can manipulate all I want in my favorite drums program.
Now that I've learned about the recordings having each drum at the end of was file I can create a drum rack in Ableton with the same sounds recorded on real drums track and still use real drums but augment with midi. looking forward to playing with this
