RESOLVED: Lookup CHOP rounding error bug I think

Hi,

I think the lookup CHOP is bugging out with some rounding errors (or something!) in version 62180 on Windows 10. If I make a default pattern CHOP and switch it to ‘‘ramp’’, plug that into a lookup CHOP as the look-up table and plug in a constant CHOP from 0-1 as the index. I will receive an output of 0 when the index is at 1 instead of the expected output of 1.

Thanks!

Turn off Cyclic range:

From the wiki:

Another option would be to set your pattern CHOP to hold on extend right - located on the Channel Page.

Dang, completely missed that one! Thanks for the quick reply Matthew. I guess I was kind of surprised I had never run into that issue before after having done loads of looking-up and assumed it was buggin’.

My bad!

Also of note is the Extend CHOP can give you the Cycle options for when you’re using CHOPs that don’t have the parameters exposed. Very useful when working with things like Event CHOPs.
