I'm already working on making this an ABC file for starbound.
EDIT: Having trouble. I was able to make it separate instruments, but I can't merge a few of them to make a solo file without all of the notes getting messed up.
EDIT 2: Done! Yay! [Download]
I haven't played enough Starbound to actually have any instruments in-game, so I'll have to try these out when I do.
You probably could have combined the two E. Piano parts, though. I imagine they would be played on the same keyboard by the same person, I just split them into two MIDI channels to make them easier to manage while I was sequencing.
The "solo" version is pretty messy. I would recommend just using the E. Piano parts, Harp, Annoying Orangeet, and Organ. That way you have the song's rhythm and melody without getting too complex.
