This shows how to set the roll interval (how fast the roll repeats).
- Hold down the [SHIFT] button and press the [ROLL] button. - Set the roll interval. Each time you press the [ROLL] button while holding down the [SHIFT] button, the roll interval changes as follows: quarter-note (1/4) Ó eighth note (1/8) Ó sixteenth note (1/16) Ó thirty-second note (1/32) Ó sixty-fourth note (1/64).   - If the roll interval (value) is longer than the sample length, the sample plays back in a loop. - The following are the conditions for roll playback or loop playback, when the tempo is 120 (bpm) and the sample length is less than a quarter note (0.5 sec.).  - When the roll interval is set to 1/64–1/8, the sample plays back as a roll. - When the roll interval is set to 1/4, the sample plays back in a loop. 
Making the roll playback interval shorter (faster) partway through
You can shorten the roll interval while it is playing back.
- Follow the steps in “Playing Back Samples in Detailed Steps (ROLL)” to make the sample roll. 
- Hold down the [ROLL] button and turn the [VALUE] knob clockwise. - This shortens the roll interval. Turning the knob counter-clockwise returns the roll interval to its original value.  - You can’t make the roll interval longer (slower) than the original value.
