Pedal editor

Edit a multi-effects guitar pedal from a phone.

The pedal’s own editor only runs on a desktop. I reverse-engineered its MIDI protocol to read and write patches, effects and parameters, and built a phone app around it.

  • The whole chain at a glance, from input to output, colour-coded by effect type.
  • Every parameter on a slider, sent to the pedal as you move it.
  • A backup of every patch before anything is written.
