How can I use an Expression Pedal with Olivera?

A TRS expression pedal can be used to remotely control any of Olivera’s knobs. By default, Olivera is configured so that an expression pedal controls the MIX knob.

To configure Olivera for expression control, press and hold the footswitch for at least 2 seconds while powering up Olivera. Once the LED flashes RED, release the footswitch. Then, turn the MIX knob counter-clockwise until the LED turns GREEN. Press the footswitch to store the EXP port assignment to EXPRESSION mode.

To change the knobs assigned to the expression pedal:

• Press and hold the footswitch for at least 3 seconds, until the LED blinks GREEN.
• Rock your expression pedal to the HEEL position. The GREEN LED will stop blinking and remain lit.
• Set the knob(s) you would like to control to the desired settings for the HEEL position of the expression pedal.
• Rock the expression pedal to the TOE position. The LED will turn RED.
• Set the knob(s) you would like to control to the desired settings for the TOE position of the expression pedal.
• Press and release the Olivera footswitch to exit and store your expression pedal setup.

Keep in mind that expression pedal assignment is saved per-preset, and not globally.
