HI Rikki, many thanks

for your reply. Yes, I did check the Window > List drop down menu, and checked each & every one of the song's blocks (tracks) for the specific Yamaha 'FF' Meta Event, of which appears when I load the same midi file into the Tyros: Song Creator > SysEx Tab Window. Strangely enough, it and all other FF type SysEx commands don't show up in my XG Works software program. Kinda weird. I'm baffled.
