Hm, something does not work properly. It sometimes stops working and jumps back in time while the frame should be frozen. Then it doesn't freeze anymore. Have to take a closer look whats going on there. I will give you feedback soon.
Ah okay, I guess I have found the (user) error.
If the LFO doesn't go max with the amplitude the frozen frame gets some kind of lost and the video goes on.
Here is a link to a short video I made to show the effect. Really great!
