Expression Pedal
An external Expression Pedal can be connected to the rear panel ¼” phone jack. The
Expression Pedal can be set up to control any combination of the ten parameters. For proper
operation the Expression Pedal should be a simple linear resistive potentiometer (“pot”) with
a maximum value of between 5k Ohms and 25k Ohms. Refer to www.eventide.com for
information on recommended expression pedals.
The Expression Pedal settings can be adjusted simply by pressing the Pedal to the full heel or
full toe position and turning the Control Knobs. You’ll notice then that whenever you move
the Pedal, the green “Edited” LED in the upper right corner blinks. This indicates that Pedal
programming is “live.” To program, press the heel completely down and adjust the knobs to
get the sound that you want for the heel down position. You must turn the knobs to create
the assignment. Knobs that are not turned are not assigned. Now, press the toe completely
down and change the settings of any or all of the knobs. Parameters associated with any
knobs that are moved will be mapped to the Pedal. Now, when you rock the pedal back and
forth, you’ll hear the sound change between the two settings.
After a few seconds of pedal and knob inactivity, the green “Edited” LED will stop flashing.
When the LED is solidly lit, you can turn any of the Parameter Control Knobs to change the
sound without changing the Expression Pedal mapping.
When the Expression Pedal is used, the Billboard will display the changing value. If the
Expression Pedal has been set up to control a single parameter, the display will show the
parameter name and value in the same way as if you were turning the Control Knob. If the
Expression Pedal has been set up to control multiple parameters, the display is a graphic
representation of the Control Knobs. Control Knobs that are controlled by the Expression
Pedal are represented as circles while unassigned Control Knobs are indicated by a solid line
(dash). The 2
nd
character from the left indicates the position of the Expression Pedal with a
value from 0-9 (0 = heel, 9 = toe).
Since any number of parameters can be programmed to respond to the pedal, it’s important
to learn how to un-assign parameters. Let’s say that you’ve programmed the Pedal to control
Mix from 50% to 100% and Delay from 10 milliseconds to 100 milliseconds. Now, you’d like
