I don't have the right tool to make FNF vocals so I used an instrument for BF's vocals. This was supposingly playable using Meekaryo's Friday Night Funkin' || Editor with chart editor (https://scratch.mit.edu/projects/519023930/) but Scratch keeps telling me that the file got too large so I just did this
This is the site I used to make the song https://onlinesequencer.net/ This is my work https://onlinesequencer.net/2727762#t0 (the koto instrument [orange notes] is BF)
