Playing Back Samples (SAMPLE MODE)
16
Playing Back Samples Only One Time (One-shot Playback)
When the sample playback mode is set to one-shot playback, the sample plays back once to the end when you press a pad.
The pad’s operations are disabled (ignored) until playback is finished.
Even if a phrase that’s shorter than the sample length is recorded in a pattern, the sample plays back to the end without returning
to the beginning (no retriggering).
This characteristic is useful for playing a long sample as a backing track.
1. Hold down the [VALUE] knob and press the [GATE] button.
This sets the sample playback mode to “one-shot playback”.
The [GATE] button blinks slowly at this time.
The loop function turns off (and the [LOOP] button goes dark) when one-shot playback is on.
