Can you explain what exactly a sound font is? I’ve heard it before, I just don’t know exactly what it means.
SoundFont is a brand name that collectively refers to a file format and associated technology that uses sample-based synthesis to play MIDI files.
Persona 5 doesn't use MIDI formats internally unlike many classic games do up to the DS on handhelds and PS1 on home consoles, so there probably isn't a soundfont for it.
I'm pretty sure Super Mario Galaxy doesn't have one (theres a fan made .SF2 of it though). Oh well.
