I sorta tend to chop up ghost hits in cubase in wav format, it's easier. Reason why is because i can put real tight decays on them, which makes the beat tighter, but you need the proper fills already in place, like hi passed amens, ride cymbals etc. Also, adding a layer or two will stop the ghost hits from sounding synthetic.
I tiny tiny bit of pitching could help sometimes and maybe a little bit of velocity fiddling but depends really, thats my view anyway. Been releasing records for five years now so must be doing something right.
