460| Customizing and editing the Sounds
Editing the loop
After editing the sample, you can fine-tune the loop.
▪ Go to the Sampling > Loop page.
The loop is a cycling portion of a sampled sound. Looping is a technique used
to reduce the sampling time, cycling a portion of the sound to create the
sustaining phase of the sound. After the attack stage, most sounds repeat
the same waveform during their sustain stage.
Reading the loop diagram
The diagram lets you fine tune the loop points, by watching at the Loop End
(left half of the diagram) and Loop Start (right half of the diagram) points
matching at the center of the diagram. A good-sounding loop is shown as a
continuous, nonbreaking line.
Use the
Zoom controls to change the size of the looping ends shown in the
diagram. When a button is greyed-out, it means the maximum or minimum
value has been reached.

Changing the loop points
▪ Be sure the Loop On checkbox is selected.
▪ Use the Loop Start parameter to adjust the Loop Start point.
▪ Use the End parameter to adjust the Loop End point (always matching the
Sample End point).
