RECALLING / UNLOADING A PRESET OR EXPRESSION SETTING

1. Press and release the EXP / PRESET button. The green LED will light,

and the Mainframe will load your saved expression setting or preset.

2. If an expression pedal is present, any knobs that are saved to the

expression setting are disabled and the expression pedal controls

those parameters. If no expression pedal is present, the Mainframe

loads the saved positions of all knobs. In both situations, the FILTER

toggle switch’s saved setting will be loaded.

3. To unload the setting or preset, press and release the EXP / PRESET

button. The green LED will turn off, and the toggle switch and any

knobs that were part of the expression pedal setting or preset will

return to What You See Is What You Get operation.

CHANGING PARAMETERS AFTER RECALL

Normally, the green LED lights solid after loading an expression setting or

preset. If the FILTER toggle switched is moved, or if a knob is moved while

a preset is loaded (with no expression pedal connected), the green LED

will blink very rapidly to indicate that the preset has been loaded but has

been altered.

RELOADING ALTERED EXPRESSION SETTINGS OR PRESETS

In the situation where an expression setting or preset has been altered

and the green LED is blinking, press and release the EXP/PRESET button

to recall the saved setting again.

SAVING ALTERED EXPRESSION SETTINGS OR PRESETS

If you would like to save an altered expression setting or preset, press and

hold the EXP/PRESET button for 1 second. The green LED will light solid,

then blink quickly once the new preset has been saved.

ERASING THE CUSTOM EXPRESSION SETTING OR PRESET

Press and hold the EXP / PRESET button. While holding it, press and

release the footswitch. The green LED will blink quickly, then light solid,

indicating that the Mainframe has loaded the factory default expression

setting and the custom expression setting or preset has been erased.
