Mulitslider Scripting

So I have these multisliders that where the height is always 1 so when I take my finger off it will always jump back to 1. Im using these silders for eq. The thing is that I would like to create a custombutton that would change the height back to 0. In other words a quick killswitch for the eq.

attached,
msHeight.jzml
is that what you need?

Cheers,

This is good but it needs something more. When the Custombutton is enabled i would still have to touch the multislider in order for it to fall back down. I need the button to automatically fall back down without touching the slider. I'm using Ableton Live. Thanks for the help!
