Learn how to wire a polarity adapter for the FC7 expression pedal.
The Yamaha FC7 is the world’s most popular expression pedal. While it works perfectly out of the box with Yamaha keyboards, the FC7’s polarity must be reversed if you want to use it with a Roland or Kurzweil keyboard.
Here’s how you can create a DIY polarity adapter for less than $10.

- Plug the FC7 expression pedal into YPP-136 breakout cable.
