I created a patch to control lights from Max via LanBox. I used the example patch "LC+ UDP tx Example.pat" available on the LanBox website as a starting point. The problem is while it works on some channels, some others are not working. I especially have problems with the first ones like 3, 4, 5, etc. Channnel 17 is not working but channel 18 is !?! I tried to use the original example patch unaltered to see if my programmation was wrong but I have exactly the same problem. The problem is not the lights because everything is ok when I use the house light mixer. I use Max 4.6.2 on a Core2Duo Macbook Pro.
