Loop function not working correctly

Hi there,

I was very happy when I found your plugin. it looked very easy to use and had all the right functions.

But now I’m trying to make the slider go really slow, with acceleration or de-acceleration, but after some time the slider ‘jumps’ to the start again instead of looping it. Am I doing something wrong?

Thanks!
