FF1 - Battle Scene (Song Hack)

I guess a lot of people are taking a break right now (I don't blame them). I have actually grown to like your FF6 intro version of this track, Emberling. I will just use that one to spare you more work. I actually figured out how to add the reverb/echo back in the song through hex editing, but I can't figure out how you changed the pitch of the instruments! I did command searches for several hours and have not located anything that changes the pitch in the song. I only saw Octave commands, but those appear the same as the original. What command is giving the instruments a higher pitch? It is not the tempo command (F0), because I noticed the speed is set the same in both tracks, just with a lower pitch for the instruments.
