Saving and Switching Between Memories
Saving to a Memory
You can save the settings you’ve edited.
1. Long-press the [MEMORY] button.
The indicator of the currently selected memory number blinks, and the memory enters write standby mode.
2. Take your finger off the [MEMORY] button.
3. Press the [MEMORY] button to select where to save the memory.
Each time you press the button, the memory selector cycles through as follows: MANUALÓ1Ó2Ó3Ó4.
You can use an external MIDI device to select memories 5–127. When you select memories 5–127, the MEMORY 1–4 indicators
all blink.
4. Long-press the [MEMORY] button once more to save.
The memory number indicators blink rapidly. Once they remain lit, the write operation is finished.
When using an external MIDI device to select memories 5–127, the MEMORY 1–4 indicators all blink rapidly and then go dark.
*If you operate the knobs or footswitch before step 3, the write operation is canceled.
*If you’ve saved to MANUAL, only the [TAPE] button and expression pedal settings are saved.
Switching Memories
Here’s how to recall a saved memory.
1. Press the [MEMORY] button or [MEMORY] switch to select the memory.
Each time you press the button/switch, the memory selector cycles through as follows: MANUALÓ1Ó2Ó3Ó4.
You can use an external MIDI device to select memories 5–127 via MIDI. When you select memories 5–127, the MEMORY 1–4
indicators all go dark.
What is “MANUAL”?
Normally, effects are applied according to the settings in memory. However, when you select MANUAL, effects are applied
according to the position of the knobs on the panel. At this time, the TAP DIVISION and expression pedal settings that are recalled
are those saved in MANUAL (which are editable).

Various Settings
Setting the Expression Pedal Function
By connecting an expression pedal (such as the EV-30, sold separately) to the CTL 1, 2/EXP jack, you can operate the top panel
knobs except for the Mode knob.
You can set the respective sounds for when the expression pedal is at MAX position (pushed all the way up with your toes) and at
MIN position (pushed all the way down with your heel), and make continuous changes to them.
You can use different expression pedal settings for MANUAL and for each memory in MEMORY 1–4 respectively.
You can also set and add a different function to the functions you’ve already set. This lets you create settings that operate multiple
knobs at once.
1. Use the [MEMORY] button to select the memory (MANUAL, MEMORY 1–4) for which you want to
configure the expression pedal.
2. Hold down the [TAP] switch and press the [TAP DIVISION] button.
The TRI indicator blinks
3. Use the respective knobs to set the sound that’s used when the pedal is at the MIN value (pushed all the
way down with your heel).
4. Press the [TAP DIVISION] button again.
The DOT indicator blinks.
5. Use the respective knobs to set the sound that’s used when the pedal is at the MAX value (pushed all the
way up with your toes).
6. Press the [TAP DIVISION] button again to exit the function settings.
If you want to clear the function settings for the expression pedal, go through steps 1 to 6 above without operating any knobs
in steps 3 and 6.
●
To save the expression pedal function settings, you must save the memory.
●Use only the specified expression pedal. Connecting expression pedals made by third-party manufacturers may
cause this unit to malfunction.
