The midi import on eof is for guitar hero/rockband files and sometimes lyrics.
Midi files don't contain any fingering information, only the note pitch so you need to convert it to gp5 (using tux guitar or guitar pro) and re-transpose it to make it actually playable, and then import the gp5 file into eof.
Generally you don't want to work from midi files unless you know what you're doing as they're a right pain, you basically have to re-tab the whole song since the automatic fingering generation in guitar pro/tux guitar isn't very good at all.
