Serato DJ has a Quantize function. When selected, your cue points will be snapped to your Beatgrids as you set them. Triggering Cue Points will also match the tempo of your Beatgrids so that you will never go out of time. You can select the number of beats between each Cue Point set and trigger in the the DJ Preferences tab of the Setup screen.
When Quantize is selected, triggering Reloop for your stored loops will also snap to the Beatgrid.
