Switching between manual/memory mode

What is “memory mode”?
The effect combinations and settings (sounds) are recalled as “memories”. There are 72 memories. Out of the 72 memories, 36 (4 memories × 9 banks) can be saved in the user banks (9 user banks and 9 banks of presets). You can use the pedal to instantly switch between banks and memories.

What is “manual mode”?
Use the [BANK ] [BANK ] pedals, the [CTL] pedal, and the [1]–[4] pedals to turn the effects on/off that you set using the panel knobs. This lets you use this unit as if you were individually switching the compact effects on an effect unit board on/off.

1. Press the [MEMORY/MANUAL] pedal.
   Press this pedal to toggle between manual mode and memory mode.

When memory mode is on, the indicator lights up red. When manual mode is on, the indicator lights up blue.

Saving a sound (memory write)

NOTE

If you turn off the power or switch to a different memory before you write the memory, the sound you created is lost. When you write a memory, the memory that is already at the save destination is lost.

   One of the pedal indicators (1–4) blinks.

2. Press the [BANK ] [BANK ] pedals or the [1]–[4] pedals to select the user bank and memory number where you want to save the memory.
