This technic of looping is simple.

2) Put the mode witch on "record".

3) Press "memory start".

4) In sincro with the first beat, press one note of the keyboard and press
"stop" on the next beat.

5) Put the mode switch on play and listen the results pressing "memory start".
(one note now repeat in sincro with the tempo).

6) Tweak now "tempo" and the "sample tune" to close the loop.

ENJOY!
