I find that Noteworthy Composer does a great job of turning Midi files into those mysterious black dots that my wife insists she needs to play. Me I use a pair of ears :-)Noteworthy will import Midi files and convert them to sheet music and a previous thread alerted me to a program that will convert ABC to Noteworthy and I have found that this works very well.
Noteworthy can be downloaded as a shareware program from www.noteworthycomposer.com
Hope this helps
