Live Control in CataRT (MuBu) Not Working

Has anyone had success using Live Control in CataRT?

I'm starting with the tutorial patch "catart-mubu-tutorial 3 live control.maxpat", but even there it doesn't seem to trigger anything. What I get is the same grain repeated at onsets or chop, depending on the segmentation method I have selected.

What I've looked into thus far:
1) The difference in output between triggering a grain in MuBu.Knn via the imubu scatterplot or from the output of "p target-analysis", which comes from a pipo desc:onseg/chop. from imubu, only the XY coordinates are sent prepended with a select message. From pipo, there's a list of 19 floats. I ran a cycle~ object through the real-time analysis and also recorded a snippet of it and ran that through the non-real-time analysis, and I could only find 1 number that corresponded to the outputs, so not sure where to go from there.

2) Range, it looks like there is a scaling function in mubu.knn, and I am wondering if this might be part of the problem. It defaults to off. I've tried setting it to minmax and meanstdev, but it doesn't seem to help. I am wondering if I need to trigger this at a particular point in time, though.

3) Messing with the random selection functions. If I open the radius and k values for mubu.knn, I can get a number of grains to playback, but they do not correlate to the target sounds, since they are randomly selected. This reinforces my belief that either the data being sent from p target-analysis isn't formatted properly for mubu.knn or is out of range.

Any help on this is appreciated!

Thanks,
David
