The only thing that I would add to what Jay says is - try to keep slack out of your line from rod tip to "bobber". The fish take midges so easy that a little slack prevents you from getting a hook set when that bobber twitches. The midge larvae and pupa move so slowly that the fish just "suck" them in and if not a real bug "spit" it out before you see a twitch and can set up on the take.

I am speaking from a "old geezer" perspective, perhaps your reaction time is faster. Ha! Ha!
