Serato Scratch Live has several different playback modes, each with their own purpose. But it seems not many DJ's know the real difference. Whenever I DJ out and work with other DJ's I've noticed many DJ's use Absolute mode, when really they should be using Relative mode. The biggest reason being is if you are in Relative mode and someone bumps your needle the song keeps on playing almost seamlessly. Also you have the ability to setup cue points. These 2 reasons are enough for most to understand why Relative mode trumps Absolute mode, yet I see many DJ's using Absolute mode.... if only they knew..
