Observing a clip slot to update LED -- Sharing my (limited) insights

Hi,

I have been working on a max device that aims at updating the LEDs of the miniLAB mk2 from Arturia, based on what is going on with a selected clip slot :
- is there a stop button ?
- is there a clip in the slot ?
- is it playing ?
- is it recording ?
- is it triggered ?

I have managed to put together something that's doing it, and I wanted to share it for several reasons. First, it seems to me that it is something many people would want, isn't it ? And since it is one of my first patch, I thought it could help other newbies. And last but not least, it would be interesting to share other ways ( and better! ) of doing it.

In edit mode, I sometimes have a "notifications" error but never in Live.

Here it is !
