Marking solo sections in Eof is very easy.
To mark a solo section, just open the song midi file in Eof and clic in the most closer beat to the solo section.
Then go to Beat->Events and tipe the following text to mark the solo:
"solo on" to mark beginning.
And "solo off" to mark ending. (in other beat, of course)
And it´s done, now open Fof and enjoy your solo!
