PlayableChords - "Shape" CV In: Does it work?

[JeffGreenlee42]

I'd like change the shape with an LFO or sequencer.. but it doesn't work. I can sometimes get it switch between two chords (Maj and Minor) if I apply 10 volts (-10 v didn't work either) but i'd like to change to any of the available chord shapes from the CV Input. Am I missing something?
