Voiceset is one of the three short tunes bundled in the software of the Creative Music System that lack any meta data, animation tags, or similar polish. Due to the poor quality of these tunes, they seem like internal test songs that were included as filler. The tune simply runs through a couple scales.
The file is named VOICESET.CMS and it's located on the Master install disk. Though the song can be played on two SAA1099 chips, it only uses one.
