How does one actually make an MIDI file work, as in, what determines the octave and the length of each note? How does the notation form a note correctly? My main software to work with this is Starbound Composer, a MIDI file renderer for the Chucklefish game Starbound.
(I'm asking about something like this segment: 3/4 ^G,3/4 [^D3^D,3/2] =G,3/2 [c/4C,/4] C/4 [d3/8^A,/8] G; taken straight from A Little Fight Mewsic by Homestuck)
Note: I'm actually hand-making the music from total scratch. Knowing no other way, I'm going to render it as a .wav using Starbound Composer, and then use Audacity to render it to .MP3
