How to create a “stop all clips” button

I keep trying to figure this out but I seems that it does not work at it should.

I manage to create an “stop all clip” option but what is happening is that it cuts the midi signal from my midi keyboard. Witch is bad!!!
In Ableton if I press the ” stop all clips ” button it just stops the clips not the midi signal.

Is there anyway to replicate that with CSS?

I would much appreciate any help!
