Instruments not playing in InstEd

[z64online2.21]

I know this sounds strange but for some reason when I create an instrument set,

I get the first instrument playing for ALL the tracks in game.

 

I'm not sure why it's doing this or what I may be doing wrong.

 

instrument data is found under the 15 header correct? as far as look up and knowing what to look for or changing anything

after that, I have not the slightest clue what to do after the 15 header lookup

When you extract from the MIDI file and get text files, you need to open each of them with notepad and change the Inst number before you recompile your track into a zseq file. By default, they're usually 0 and in some rare cases it'll be something else, but usually 0. So if you set it to Hyrule Field's set, if you want the trumpet, change the Inst from 0 to 5. If you want strings, change it from 0 to 10 or 11.

Also, the 15 header is just to change the track number, it has nothing to do with the sets themselves. You can actually change what set a track uses with Insted. I can't remember offhand which option you choose, but it's pretty self explanatory.
