If I setup my strip in 2 segments, if I apply an effect to both it smoothly goes from one segment to another. However if I change the speed on the second one, they get out of sync. I tried doing a playlist of running 1st segment, then second segment - but they seem to start simultaneously. How can I keep a smooth effect across 2 segment, but having it run more slowly on the 2nd segment? ![image](https://global.discourse-cdn.com/free1/uploads/wled/original/2X/9/94dec460ac5deb86ba8dcfc113a4b557b7e2bca9.png) ---

you can not. And that is not even mathematically possible if I understand correctly. ---

What does the playlist feature do then? I thought it would play one effect, followed by another?
