How to use modifier for LED feedback instead of ‘None’ In Session Box

Hi everyone,
I know this topic has been discussed a lot already, but I’ll try anyway 🙂 I’m creating a script for my APC Mini mk2 and I’m having trouble with the clip LED feedback colors.

Following the guide and using the JSON shared by Admin on October 2, 2021 (link here), I managed to map Ableton clip colors to the APC Mini mk2. Basically:

• m1 = Ableton color index (for the 70 available colors)

• m2 = velocity value corresponding to the LED on the controller (e.g., m1 = 14 → m2 = 72 = red)

The problem appears in the Session Box: in current CSS versions, at the bottom of the reaction there are global LED Feedback settings. I suspect these override the modifiers: for example, if I set Clip Stopped = 0, all stopped clips appear off (on the APC Mini mk2, velocity 0 = LED off).

If I leave it as None, the controller interprets it as velocity 127 (issue also discussed here).

The workaround I thought of would be to create a reaction like “every time the controller receives velocity 0, replace it with m2”, so the pads would get the correct value, bypassing the “None/0” issue.
Do you think this is doable? Has anyone tried something similar?

Or, more simply: is there any way to assign m2 instead of ‘None’ in the LED Feedback settings of the Session Box reaction?

Thanks a lot to anyone who can clarify this 🙏
