Click the appropriate radio button to select the sample loop that will be affected by the crossfade. Most samples only have one loop: the sustaining loop. If a sample contains two loops, the second loop is called the release loop.

The graph shows you where the crossfade will occur. The three areas (from left to right) represent the sound before, inside, and following the loop points, and are displayed with different sloped lines.

For example, when performing a Sustaining loop crossfade with no Post-Loop, you can see the loop data fade out as data from the Pre-Loop is mixed in to form a crossfade.

Select the check box and drag the slider to determine how much of the selected sample loop will be crossfaded. The end of the sample loop is crossfaded with the end of the region before the loop start to make the end of the loop blend smoothly with the beginning of the loop.

Select the check box and drag the slider to determine how much of the region following the loop end is crossfaded. The region following the sample loop is blended with the beginning of the sample loop to make the transition from the end of the loop to the rest of the sample following the loop smoother.

Post-Loop crossfading is only necessary if the sampler will play beyond the loop points.

Choose a mode from the drop-down list to determine how the Preview button will work:

Loop the Loop
Plays the loop area only.

Play Loop through Post-Loop
Plays the loop once and then the Post-Loop.

Play as One Shot
Plays from the beginning of the file and uses the loop settings to determine how many times to loop each loop.
