How do the Ottomans get their special marching music?

So I'm working on something that has a unit that plays marches for the infantry. In order to save space by not having to edit dozens of unit that use European flutists, I decided to try the Ottoman method and just delete the abillity for their units to play music. I've realized this is more difficult than it sounds.

Even after giving my unit the Ottoman drummer and thier disguised flutist (he looks like he plays a trumpet, but his role is the flutist) they're still mute and my unit won't play the music. I also swapped out the Egyptian Musicians files for ones of marchers and named them back. I also made the drummer and flutist use the European skins for their instruments.

The faction is also Prussia, does this have anything to do with it?

I figured it was too difficult to figure out the Ottomans, so I just took out every European units' flutists and gave them to my unit. Problem is that only one march plays for the entire faction. There a way to make a faction play all 6 marches?
