I have a base human CAT and have attached it to a node that is constrained to a spline. I have a 300 frame animation and have 300 set for the end of the CatMotion Range.

Under ‘Stride Parameters’ no matter what settings I use for ‘Max Step Time’ and ‘Max Stride Length’ I always have a ‘Velocity’ of .842 as it never changes. I’m trying to get a really slow walk of about one step per second.

I set my stride length of a comfortable distance so it doesn’t look like the rig is taking too long of a step and then I drive my ‘Max Step Time’ up to try to slow things down but it doesn’t change anything. I’m obviously overlooking something.

I’m going to answer my own question in case it helps someone else.

The velocity is a function of the length of the spline. I shortened my spline and the velocity changed. Problem solved.

If using a Path Node, the velocity is governed by that. so altering the nodes animation alters the speed, however it is animated. For example with a path contraint, the timing and valuse of the Percentage keys affect it as well as the path length.
BTW, you can use the CAT forum to post CAT questions.
