multiple Devices onof states

Hello,

I have tried to make a script for my Launchpad, where the first grid-button controls the on/of state of the first device, the second button the on/of state of the second device, etc.

(like the second row of buttons from the top in device mode on the Push controller).

I failed, the result I get is that only the first button works, and only on the selected device, this is what I did,,,

On the app I activate the "add new mapping" button, then the "Device on/of " state button, and on that page I activate "specific" for track state, Specific track number "1", and then for the first grid knob I use Device chain number "1", the second Device chain number "2", etc.

(And of-course the name, the led on/of states, and midi-learn for the grid-buttons)

What am I doing wrong, can you help me out ?
