Thats pretty much what i do now,its just handy leaving it as midi just to put finshing touches to it.
I used to use Logic and that was a piece of piss dead simple,all track automation was the same for midi and audio.I stoped using it coz they stoped maken it for PC's and i couldn be assed geting into a Mac i dont know any one that know's anything about them,I dont even know a shop that know's anything about them so i fked it off and got into Cuebass.
I do like Cuebass its got some good feturesbut alot of defect's,and something's are just fking awkward.
Logic is what it's called...Logic,it's simple.
