Nightwing help

Hey guys just picked up the game and loving it. My favorite character is nightwing and I just cant seem to get something down. For those of you using nightwing, please explain to me how you switch to your staff in mid combo so fast? I cant seem to do it. I’ve seen videos of people juggling someone in the air and boom switch to the staff and do a nasty combo. I’m using a 8-button fighting stick and havent changed any settings in terms of controls. If you have any tips, please help me
