Anyone here controlling Chord Pad with Leap Motion and Geco ?

Hi guys,
I’m very impressed and inspired by these videos:

So - I’ve installed Leap Motion and Geco, and mapped left/right and up/down movements to Chordpads voicing and tension modifiers.
It’s working pretty well, but it’s kind of flimsy - it’s difficult to move only one parameter at the time.
In the leap motion visualizer everything moves as expected so I think the problem lies with Geco.
I’m very interested in how you have set the parameters in Geco - especially in the advanced section.
Any advice ?
