Hi, EricDano -

This is what the user manual says about MGX files:

Quote:

You can open an entire MIDI file into Band-in-a-Box. The chords will be automatically interpreted by the Chord Wizard and the MIDI file will play and display on the Melody track. A “silent” style will be loaded so you'll only hear the MIDI file. When the file is saved, the extension will be MGX, allowing you to easily identify the BB songs that you have that contain entire MIDI files.

You could also use the powerful music making features of Band-in-a-Box to create new accompaniments, add harmonies, add soloing, and embellish the melody. And when you're finished, you can always resave your song as a MIDI file again.




I don't have the Mac version, so I don't know if they implemented the multi-channel sequencer for the melody and soloist tracks. If not, that's probably why the Mac won't read an MGX file.
