Source & loop
Loop & grid
Bar, half, beat and eighth all need a detected tempo.
Work on one section of the source instead of all of it.
Turn loop on and a section of the source repeats. The loop can optionally snap to a bar, half a bar, a beat, or an eighth (granular adjustments with the ÷2 and ×2 buttons).
Why it matters
Looping can allow you to focus on a specific section and iterate until you get the result you want. It can also be useful for exploration and creating variations on a theme.
