Which Guitar Hero spin-off uses a turntable controller?

DJ Hero is the Guitar Hero spin-off that uses a turntable controller.

Released in 2009, DJ Hero shifted the series from simulated guitar performance to turntablism, the art of combining recorded tracks with scratching, crossfading, and effects. Its custom wireless deck included a rotatable turntable, three stream buttons, an effects dial, and a crossfader. Players used those controls to follow on-screen patterns and perform virtual DJ mixes.

The game was developed as the first Guitar Hero spin-off and featured 94 remixes, generally combining two songs from different genres. It also included a DJ-versus-guitar mode for selected tracks, allowing one player to use the turntable while another used a compatible Guitar Hero guitar controller.

Amplitude and Rock Band are easy alternatives to confuse with it because they are also rhythm games, but neither is the turntable-focused Guitar Hero spin-off. DJ Hero 2 later reused the same controller and expanded the series with more multiplayer and battle modes.
