Hi, i know seems old but still, cannot get it to work.
Using a Midimix. Watched the video, makes totally sense but in my case doesn´t work.

Controller scipt led on 127 off 0

Want to light up when specific mode is on / or track highlight. Tried custom and default on script /mode/highlight - nothing

Choosing the right button . Am on MID channel 16, is that a problem?

Hi rebbarth, sorry for the slow reply.
I am testing with a Midi Mix here, LEDs work correctly when Mode is active/inactive and Track selection.
Can you clarify what you mean by you're on channel 16? are the controls on the midimix changed to channel 16 or something else?

In Ableton's preferences, do you have track and remote turned on for the input/out options of your script (see attached screenshot). This is needed for LED feedback to be sent to your controller from live.

As I mentioned, I tested with a Midimix controller myself and all worked correctly so not sure what else it could be.
