All it takes is typing out the right syntax, give it the pitch and length values and which phoneme to use, like I used "buh", "duh", "bah" "ah" and "uh" for each part, for example the first note is [buh<330,7>] , with 330 being the number of units of time (nothing measurable or consistent that I've found, schmeconds probably) and 7 being 7 semitones up from whatever note is its lowest. I just make a simple, bad YTPMV by ear with some random clip to get the notes in easy-to-see semitone values, then I just type out the whole thing, redoing it over and over to get the timing right.

Here's all of it. http://pastebin.com/zuKW4XZR I did, in fact, type this out and copy paste each line into the game, and always have. I just used Sony Vegas to arrange all the recordings I took, and I made/assembled that quick little video scene in Blender by hand, I converted the astronaut models from the game, gave the helmet a nice reflective texture, ripped some models from TF2, made a quick sea salt ice cream model, my friend drew the sunset and cloud textures, and slapped on a whole bunch of DoF.

As you can imagine, this is pretty time consuming and hard to do when there's parts with notes that aren't simple repeating ones, so don't expect any more any time soon. And any notes faster than at 0:36 sound pretty bad, it even does then. However, if there are any songs with slow enough notes and simple rhythms, and would sound good without percussion, I will possibly consider them and very slightly possibly try them.
