4. If necessary, press the TAP TEMPO button several times to set the tempo.
You can also set the tempo by pressing the right pedal instead of the TAP TEMPO
button.
* For details on setting the tempo, refer to "Setting the tempo" (p. 33).
* It is not possible to adjust the tempo beyond a certain limit.
5. Press the left pedal to begin playback.
6. When you wish to overdub along with the phrase, press the left pedal.
Each time you press the left pedal, you will switch between playback and overdubbing
modes.
• To cancel (undo) the most recently recorded overdub, hold down the left pedal for at
least two seconds. When you undo an overdub, the OVERDUB indicator flashes.
* You cannot undo if the unit only has a slight amount of memory left (the OVERDUB
indicator does not flash even if the left pedal is held down for two seconds or more).
• To restore (redo) a cancelled overdub, hold down the left pedal again for at least two
seconds. When you redo an overdub, the OVERDUB indicator flashes.
• To undo all overdubbed sounds (clear), hold down the right pedal for at least two
seconds. Cleared overdubs cannot be restored.
* If the internal memory is used up, overdubbing may stop before you are finished. If this
occurs, erase unnecessary phrases (p. 31), and try the operation again.
7. When you are finished playing or overdubbing, press the right pedal.
8. Press the WRITE button, getting the indicator to start flashing. To save the
data in the same phrase track, press the WRITE button once again.
If you wish to save the data in a different phrase track, press the WRITE button (so its
indicator is flashing), use the PHRASE SELECT knob to select the desired save
destination, and then press the WRITE button once again.
* For details on saving, refer to "Saving a phrase" (p. 29).
* If you continue looping in Overdub mode, unwanted noise will also be recorded repeatedly.
You should use Overdub mode only while recording a phrase.
