Hi ...
I'm surprised that the MFD file is so "protected" ... all it has in it is the names of songs, the name of a style, the tempo, etc. Essentially it has "pointers" to styles etc., but no actual song (note) data is in the MFD file. As someone else said, it's sort of a mini-registration with a few settings for songs. It doesn't contain the actual song (note data) and it doesn't contain intros and endings - just a pointer to a style that is in the T5, and what tempo to play it at (mainly).
So, I'm surprised they "protect" it so much. I could see if it were actual MIDI files of actual songs, bit the MFD file is much smaller and simpler than that ...
