One Instrument That Plays All Of The Pieces

Starbound really needs an instrument that allows one player to singlehandedly play all pieces of a song. Whenever I make new .abc files with multiple parts, I can never play them properly in game alone, and that's no fun. For an example, take the Wanderlust songs. Most of them require multiple players... We need some way to become a one-man band. An instrument with that sort of capability would be best, but I suppose a hand-held jukebox or music player might work... as long as others could hear it like normal.
