10. Program -/+ Buttons
Use these buttons to edit the Program Number. In
the Metronome or Tap mode, eight different num-
bers are available; and in the Tune mode, another
eight numbers are available. In the Loop mode,
you can select the Program Number to start with.
By pressing the - button and + button at the same
time, Program Number 1 is automatically se-
lected, which may be useful for starting the rhythm
in the Loop mode.

11. Beat Buttons 1/2
(available in the Metronome or Tap Mode)
This sets the beat, given that is one beat. Each
press of the button changes the beat like this: 1, 2,
... 8, which is shown in the display.
Normally, you do not use Beat 2 so it can be
switched off. However, it can be effectively used
to create a complex beat by combining Beat 1 and
Beat 2.
* Beat 2 can be turned off (the indicator goes out). If you
wish to use only Beat 1, turn Beat 2 off.
(Metronome Mode)
