Turning on all the LEDs for the pads I have mapped when the script is loaded

What I’ve noticed is that when I first open the Ableton and the script is loaded I don’t have any of the LEDs on my controller on. Sometime some of them are on but with the wrong colour. As soon as I start pressing them they are being activated with the right color.

Is there anyway to integrate this: when the Ableton and my project is loaded the controller would respond with turning on all the leds that I have mapped

does this makes sense?
