i dont get it... it sounds like you want to either use software & ableton, or either use hardware alone. maybe both?? fm8 and my machinedrum work great together
edit: just saw the 2nd post on cubase... does cubase do seperate groove control for each midi track... pretty handy id say. i never really use swing in ableton, coz its a bit of pain. usually just go for the hardware for that.
