Setting up your Expression Pedal

1. After connecting to the Editor, navigate to the Controller Settings tab and open the Configure Omniports section.
   
   

Open

2. For the desired Omniport, select Expression as the Omniport setting and then set the Expression Sensitivity before clicking on Save Settings. At this point, you will not be able to calibrate the Expression pedal. The controller needs to be restarted in order for the new Omniport settings to load.

3. After restarting the device, go back to the Configure Omniports section and click on Calibrate Expression Pedal. The controller will enter a calibration menu.

Calibration Menu

In the calibration procedure, you can set the Expression Pedal type.

Expression Type

There are 2 types of expression pedal.

Voltage Dividers

Most expression pedals are wired as voltage dividers and require a TRS cable to be connected.

Rheostat

Some expression pedals, like those made for Line6 products, are wired as Rheostats where it is possible to just use a TS cable to connect.

Setting the Heel Down position

After setting the Expression Type, the controller will indicate that it wants to read the value when the Expression Pedal is in a Heel Down position.

Move your Expression Pedal to the heel down position. You’ll see the values changing on the controller.

The actual value does not matter.

Select Next, and the controller will indicate that it is saving the Heel Down value. Do not move the Expression Pedal during this process.

Setting the Toe Down position

After setting the Heel Down position, you’ll need to set the Toe Down position. The process is similar to setting the Heel Down position.

Calibration complete

After saving the Toe Down position, the calibration process is now complete. You should be able to get the full range (0-100%) of values.
