As advances were made in silicon technology and costs fell, a definitively new generation of arcade machines and home consoles allowed for great changes in accompanying music. In arcades, machines based on the Motorola 68000 CPU and accompanying various Yamaha YM programmable sound generator sound chips allowed for several more tones or "channels" of sound, sometimes eight or more. The earliest known example of this was Sega's 1980 arcade game "Carnival", which used an AY-3-8910 chip to create an electronic rendition of the classical 1889 composition "Over The Waves" by Juventino Rosas.
