Handling sustain pedals with my KL88

This article worth for KL-88 firmware revision higher or equal to 1.1.0.4, available here

1. How do I recognize if my sustain pedal is made with a switch or with a potentiometer



There is basically 2 kind of sustain pedals.

Most of the time sustain pedal act as a switch. Those pedals will have a TS type jack plug.

If your pedal have a TRS jack it means that you have a continuous type of pedal.

2. With a standard sustain



By default the Keylab 88 will handle any sustain pedal witch acts like a switch.

If your pedal acts reversely simply set the sustain on “Inverted control” instead of “Control” mode:



  • Press your pedal

  • Press “Edit” then “Mode”

  • Turn “Value” knob and select “Invert Ctrl”

  • Press “Value” knob to validate your choice



3. With a continuous sustain pedal or expression pedal

In order to toggle sustain with a continuous sustain pedal you must set it as an “inverted control”:

  • Press your pedal

  • Press “Edit” then “Mode”

  • Turn “Value” knob and select “Invert Ctrl”

  • Press “Value” knob to validate your choice


Then in the Global menu you’ll be able to set the threshold.


  • Press “Edit” then “Global”

  • Navigate with “Param” knob and choose “SustThres”

  • Press your sustain pedal

    • On the bottom right of the display you should see the actual value sent by your pedal

  • Turn “Value” knob and choose a value below the value sent by your pedal.

  • Press “Value” knob to validate your choice
