What Is The Mission Engineering Expressionator?

The Expressionator multi-expression controller allows musicians to connect one expression pedal with up to three expression enabled effects and control them individually or simultaneously. Expressionator provides a powerful set of features for expression control.

  1. Three stomp switch selectable expression outputs.
  2. Five programmable taper options.
  3. Three color LED channel selection indication.
  4. LED pedal position indicator.
  5. Internal memory to save presets.

How Do You Use The Mission Engineering Expressionator?

Using Expressionator is simple. Connect an expression pedal to the input with a TRS cable. (The Expressionator works perfectly with the Mission EP-1 expression pedal.) Then, connect the outputs to the expression pedal inputs on your effects.

With this setup (Expressionator plus expression pedal) you can use the stomp switch to cycle the expression pedal between the different effects. You can control each effect individually, or program the Expressionator to control any combination simultaneously. You can even control the taper of the expression pedal response.


  • Linear Normal control
  • Reverse Linear Heel and toe are reversed
  • Reverse Log For use with volume pedals
  • Saw Ramps 16x with each full sweep
  • Square Toggles min to max 16x with each full sweep

Can You Save Settings?

Programs are saved to flash memory so that your settings are ready to go when you power on.

Will The Expressionator Work With My Effects Unit?

The Expressionator is compatible with expression pedal inputs on most stomp boxes, MIDI controllers and multi effects units. A compatibility matrix will be available soon on the Mission Engineering web-site, to include a list of those units tested.

Do You Recommend An Expression Pedals For Use With The Expressionator?

The Expressionator works great with the Mission EP-1 Expression pedal and can control many effects units, stomp boxes and MIDI controllers with a TRS expression pedal input.
