breakpoint envelope and midi

[auralsculpture]

I downloaded the ADSR01 template and can see how it works with OSC - (at least in the output direction, couldn't get feedback from reaktor)
But how do I set it up for MIDI feedback? I can send a scaled controller from each of the ADSR elements, but they don't receive MIDI back in, or rather they do and are reflected in the monitor, but don't move the breakpoints ...
I have uploaded the template and a simple Reaktor end that I'm using to test - - -
