Something wrong in how I'm using the slope chop?

I’m inputting a panel’s U and V channels into a slope chop.

In my mind, the slope is the difference between two samples. No matter what option (i.e. previous and current sample) I use, the slope channels are always 0 even though the UV input channels are always changing.

What am I doing wrong?

thanks,
dani

Not sure how your input channels are changing (continuously or jumping form value to value?), but sometimes its hard to see the value in the viewer. I recommend appending a Trail CHOP to monitor the output more closely. If its still not working, save your CHOPs in a .tox and post please.
