editing pre-made midi files

Im a guitarist by trade and not much of a keys guy so I'm thinking I can d/l existing midi files and edit them...
there are plenty of free midi players, and u can see the separate instruments...but whats available to edit them?
I have access to some software and havent found anything yet that will do what I want to do. I want to change individual intruments, edit notes, add effects...can anyone help?
