 ## Clearing pedals
 In contrast to the original implementation on [rgerganov/footswitch](https://github.com/rgerganov/footswitch), this implementation does not clear foot pedals if they are not explicitly set during a write operation. To clear the configuration of a pedal, a separate function has to be explicitly invoked.
