@Julusian I edited the source code a little bit to fit for my needs. Veeeery slowly I´m getting into this and understand what happens where. 
Added this Loop warning as some guys of my crew forget to disable the loop in Caspar. - It´s there if the clip is on loop.
Guess I will add an “paused” or similar in the middle of the screen when the clips is on hold… We´ll see… so far so good.
Thanks again for your initial help with this!
