The switch pedal triggers on pedal release: it should be on pedal press #24

it could be caused by a swapped soldering in jack input

Upon further investigation the problem is tied to the type of Pedal attached: the D9 expects a NO (normally open) switch, while I was using a NC (Normally closed) one (like commonly used by Roland and others).

The easiest fix is to use a NO Pedal or a pedal where you can change from NC to NO. It could be nice to have a fix in the software: or just "listen" on !fell() or some sort of auto testing.

For the moment we can keep it as is and add a note that we need a NO pedal
