Using the Looper
You can use the looper by connecting a footswitch (FS-5U, FS-6, FS-7; sold separately) to the FOOT SW jack.
You can record up to 90 seconds (in mono) and play back the recorded section over and over. You can also layer additional performances with the recording
as it plays back (overdubbing). This lets you create real-time backing performances on the fly.
* The factory default setting is set to a maximum of 45 seconds (stereo). With the dedicated software (p. 4) or mobile device app (p. 9), you can select up to
a maximum of 90 seconds (mono).
Recording
Recording starts.
Press the footswitch
(connected via the ring) to
switch to playback, at the
point where you want to
loop.
Stop/clear
If you press the footswitch (connected via the
ring) twice in one second, the looper stops.
Hold for two seconds or longer to clear the
phrase.
* Once you reach the maximum available recording time, the unit automatically switches to playback mode.
* Anything you record is lost once you turn off the power.
