Bc2000 (for the BCF2000 & BCR2000)

I have my own lighting desk software and would like to use my BCR2000 as a control surface. When I investigated this a few years ago, I struggled to do something really simple, which is to set the value of one of the LED knobs.

What I want to happen is that when I load a scene, I can set all the knobs to the stored values for the lights in that scene and to have those values reflected in the LEDs. Then, if I turn a knob, I want messages from the controller to my software and for the LED to update accordingly. The values range from 0-255 for each lamp.

I recall that this was very difficult to actually get to work, but I wondered if it had been solved by any firmware updates or improved knowledge of the protocols.
