Has this ever happened to you? You plug in your sustain pedal to your Yamaha Genos and suddenly it is working the opposite way around. When your foot is off the pedal the sound is sustained, and when you place your foot on the pedal it stops. This can be very frustrating! Luckily it is rather an easy problem to fix and in the video below Chris explains how to do it.
(Remember that you should always make sure your keyboard is turned off when plugging in a pedal, otherwise it automatically reverses the polarity setting).
