Hi there, thanks fpr feedback.
You've answered my question subconscious

Only the first 6 LEDs should turon off and only the selected should turon on. ( this was in the programm so far...)
You say: programming was fine and cuecore does that we want.

So, when it doesnt work on my desk, i'm not as stupid as i'm thinking. Maybe it's the composition of my hardware:
Ipad- mini -> via "thunderboldt-ethernet-WLAN-brige" through my Macbook to the network (router,- repaeter,firewalls,and some kind of stuff like that ) -> to cuecore (aktion->aktionlist->sent OSC) and all the way back to the Ipad.
So i will try it with a >>simple-network<<
Thanks a lot. Greetings to Maartin and Zoe
