Loop Start (seconds)

Starting point for the loop segment within the audio file.

Loop Length (0.1-30.0 seconds)

0.1 2 30

Duration of each loop repetition. Shorter values = faster rhythmic patterns.

Repetitions (1-100)

1 4 100

Number of times the loop segment repeats. Higher values = longer loop sequences.

Crossfade Time (0-2.0 seconds)

0 0.1 2

Smooth transition between loop repetitions. Helps eliminate audible seams.

Tempo Synchronization

Attempt to match loop length to musical tempo. May affect audio quality.

Preserve Original Pitch

Maintain original pitch when adjusting tempo. When off, tempo changes affect pitch.

Wet/Dry Mix (0-1.0)

0 1 1

Balance between dry (original) and wet (looped) signal.
