Grab a free/light copy of Live. Drag in all the tracks you want to examine. Turn of warp for all clips. Loop a few sections of drums, right click and select ‘extract drums to new midi track’.
It will generate midi clips from the tracks you feed it with timing and volocity included.
Some hits/sounds might get mixed up, like a cymbal hitting on a snare track, but it’s easly moved to the correct place without fucking the groove.
At the very least you’ll get some idea on how the drums are played/programed on your favourite tracks.
