Are you talking about being able to shift the beat grid of analyzed songs? If so, this function is available in Export & Performance mode. As long as the analysis lock is not engaged. In Performance mode, you have to select it because it is hidden. Let's say a track is loaded in deck 1, under the #1 for that deck there is a drop down arrow. Click it and you will see "Pad mode, Memory Cue, & Grid". Select "Grid" and ensure the analysis lock is not engaged.
