1. Copied all my mp3 and midi files to the same place on the PA4X hard drive
as they were placed on PA3X.
2. Retrieved PA3X songbook into songbook editor.
Multiedit all the songs "Unit" in the songbook editor from PA3X unit: [KD_HD]
to the current PA4X unit: [KORG HD]
3. Saved songbook and loaded it into PA4X.
Everything looks like it works fine .....
