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 ...

If there was any feature that Yamaha needs to TOTALLY OVERHAUL on its arranger KB's it's the MFD!!!!

.......
they really should take a BIG look & lesson from KORG's "SONGBOOK" on this ASAP! and while their at it change the VH2 to a TC Helicon VH internal unit.
