It’s a drum track, so you have several options:
- Change all the notes to their respective notes in FE7’s drum instrument. Most of them look like snares so you could change to to D3’s and the Cs are obviously cymbals so you could change those to C#4’s. (this is probably the easiest way)
- Make a custom drum instrument with all the right samples corresponding to the existing notes
See this topic for more info on drum instruments
Either way you may need to open up the sf2 in Viena to check what notes are which because I’m not sure if all of them are just snares and cymbals.
