POWERING UP WITH A SAVED PRESET OR EXPRESSION SETTING
If power is removed from the Mainframe while a preset or expression
setting is active, it will be active when the Mainframe is powered up again,
regardless of knob and toggle switch position.
Note: If there are alterations that haven’t been saved when power is
removed from the Mainframe, the changes will be lost and the saved
version of the preset or expression setting will be loaded.
EXPRESSION PEDAL SPECIFICATIONS AND COMPATIBILITY
The Mainframe accepts an expression pedal with TRS plug or control
voltage (CV) on a TS plug at its EXP phonejack. The polarity of the
expression pedal’s plug must have the Sleeve connected to the heel
position (usually GND), Ring connected to the toe position and the Tip
connected to the wiper. The nominal expression pedal impedance is 10kΩ
though most other values will work fine. Please do not go below 6kΩ on
your expression pedal’s potentiometer impedance. Some suggested

can be connected to a CV source using a TS plug; the acceptable control
voltage range is 0V to 5V.
