The reason I dropped that info in there, is because it’s a common thing you’ll probably use a lot and I know some people who took some time to figure that one out.
DJ software does have auto cue. Usually it will have some sort of volume treshold and then (depending on snap) either snap to the first beat after that treshold is reached or right at the treshold without snap. But yes, in preparing a track you will often find the best place to have your track load and mark that as the load-in point.
Some software/controller combo’s work the same way, but not everybody does it that way or uses it that way (since you don’t need to with properly prepared tracks 😀 ).
