How to make a stepping animation material?

HI there.

I have a texture with a text. This text will be put into a display and animated with panner. I want the animation to be stepped, not smooth as usual. Take as an example a stereo display which shows you the name of the track that you’re listening.

i know that there is a steppingpannertime function in the material editor, and probably it’s the solution. But after a lot of experiments, i’m not able to use it. Ca you please explain me how to achieve the desired effect ?

thank you!

See docs for ceil node [ceil node][2] works great for such things

In panner node speedX I set to 0.1
