The unit never gained enough popularity and was in production for only a year. The Atari Video Music, available in 1976. Music visualization may be achieved in a 2D or a 3D coordinate system where up to 6 dimensions can be modified, the 4th, 5th and 6th dimensions being color, intensity and transparency. Another possible distinction is seen by some in the ability of some music visualization systems (such as Geiss' MilkDrop) to create different visualizations for each song or audio every time the program is run, in contrast to other forms of music visualization (such as music videos or a laser lighting display) which always show the same visualization.
'Music visualization' can be defined, in contrast to previous existing pre-generated music plus visualization combinations (as for example music videos), by its characteristic as being real-time generated. 6 List of media players supporting visualization.
