Playing Back Samples in Detailed Steps (ROLL)
You can use the roll function to repeatedly play back samples at a set interval.
1. Hold down the [ROLL] button and press pads [1]–[16].
The sample plays back as a roll.
You can play back up to four samples at the same time as a roll.
Using a roll during sample playback
You can make a sample roll while it is playing back.
1. Press pads [1]–[16].
The sample plays back.
2. Press the [ROLL] button to turn the roll on (the button lights up).
The sample plays back rolled.
3. Press the [ROLL] button again to stop the roll while it is playing back.
The roll starts once you take your finger off the [ROLL] button after pressing it.
To play rolls with the correct timing, press the [ROLL] button just before the roll should begin, and take your finger off the
button at the desired timing.
Setting the Roll Interval
This shows how to set the roll interval (how fast the roll repeats).
1. 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.).
