Do not touch the touch keys when the power is turned on.

If the unit starts up with them touched and does not operate correctly, please turn the power again.

Diagnostic Mode

The pedal is equipped with a mode that allows you to internally check if the controls and inputs/outputs are working properly.

Turn on the power while holding down the CLOCK button.

The data for the diagnostic mode is written and the unit enters the diagnostic mode.

Do not unplug the power supply at this time.

Before entering the diagnostic mode, be sure to unplug all plugs.

When you enter the diagnostic mode, you will first be moved to the view of checking the controls and LEDs.
Check that the three LEDs are glowing white.
Tact switch/knob push/foot switch
Press each twice to invert the corresponding symbols.
Rotating the Knob
Turning the knob twice to the left or right will invert the corresponding symbols.
Touch each one once to reverse the corresponding symbol.

After confirming that all controls are checked and working properly, it will automatically move to the internal signal check view.

Go on to the internal signal check.

In this view, you can check if the audio input/output, expression input, clean signal, wet signal, three DSP control signals, and MIDI input are working properly.


Compare the waveforms of INPUT and EXP at the top of the display.

If they are working properly, the same waveform will be displayed.


Compare the DSP waveforms on the right side of the screen with those corresponding to POT 0-2 on the left side of the middle row of the screen.

If it is working properly, the amplitude of the DSP will increase or decrease in accordance with the movement of the POT.


Compare the Clean and Wet waveforms on the left side of the lower part of the screen with the OUTPUT waveform on the right side.

Check if the amplitude of the OUTPUT becomes larger or smaller in response to the movement of Clean and Wet.


Connect a MIDI cable and send one of any MIDI NOTE from the master side.

If MIDI data is received correctly, ”X” will appear in the box at the bottom left of the screen.

Unplug the power cable to complete the process.

The next time the power is turned on after diagnostic mode, the unit will perform an internal initialization operation to return to normal mode before starting up. At this time, never disconnect the power plug.

(User preset and user scale will not be initialized)

Factory Reset

All settings can be reset to the factory defaults.

When the power is turned on while holding down PATCH/BANK, the factory reset selection menu appears.

You can execute the reset with the left footswitch and cancel it with the right switch.

At this time, never disconnect the power plug.
