Beat loop
A beat loop repeats a section of fixed musical length, set with a single press: one, two, four or eight beats. The player places the in and out points from the beatgrid, so the loop is musically exact.
In practice
One press, one exact loop — as accurate as the beatgrid behind it and no more.
Four and eight beats are the working sizes: four is short enough to hold attention and eight survives repetition. Halving and doubling from there is the fast way to build tension, since each halving is heard as an increase in intensity without anything else changing. If a loop sounds like it stumbles, check the grid rather than the loop length. And exit on a phrase boundary — a loop released mid-phrase leaves the arrangement in the wrong place even though the beat is fine.

What its accuracy depends on
Where these come from: Standard beat-loop behaviour and working practice on club players — documented behaviour, not catalog figures. For what we can measure, see what it is only as good as.
Why it matters
It is the loop you use in practice, because it needs no accuracy from you. One press gives a perfectly timed four-beat loop, which means looping stops being a technique you might get wrong and becomes something you can reach for mid-transition without thinking.
It also inherits every problem the beatgrid has. A track whose grid is a beat off produces a loop that is a beat off, and it will repeat that error indefinitely and confidently — which is why a bad loop is almost always a grid problem rather than a looping one.
Frequently asked
Why does my loop sound off?+
Almost always the beatgrid. A beat loop places its in and out points from the grid, so a grid that is a beat out produces a loop that repeats that error forever.
What is the difference between a beat loop and a manual loop?+
A beat loop uses a fixed musical length taken from the grid in one press. A manual loop uses in and out points you set by hand, which is what you need when the grid is wrong or the section is irregular.
What loop length should I use?+
Four or eight beats for most purposes. Halving from there builds intensity quickly, which is the standard way to use loops to raise tension.

Manual loop
A manual loop is set by pressing an in point and an out point by hand rather than choosing a beat length. It can be any duration, including one the beatgrid does not describe.
Beatgrid
A beatgrid is the map your DJ software lays over a track marking where every beat falls. Once it is right, sync, looping and quantise all work; once it is wrong, everything built on top of it is wrong too.
Loop roll
A loop roll repeats a short slice of the track — usually a beat or less — while the record keeps running underneath. Release it and playback continues from where it would have been, so nothing is lost.
Loop out
Looping out holds the end of a track in a loop so it keeps playing while you bring the next one in. It replaces a fixed outro with one you can extend for as long as the transition needs.
