I know what a MIDI file is. THE THING IS, sometimes the Devs will mistake a 16 bit song with the sound of a MIDI file which is very similar to an extent, I was asking for clarification in that regard. So much so that it's a very unusual request for a Dev to want MIDI files in his game instead of the classic 8 Bit / 16 Bit / 32 Bit NES / SNES / PS1 era.
