how to make an fnf chromatic AND soundfont WITHOUT fl studio (tutorial)

ever wanted to make a chromatic/soundfont for a friday night funkin' mod/song but never had any idea how to? or knew how to, but don't have fl studio?
i was experiencing this dilemma a little while back, but thankfully, i discovered some easy tactics to begin making soundfonts for free.
