Thanks man, that's great. Once I was accidently able to get some results from the Corona Light and Xpresso so I baked it (using the Timeline function>bake) to use in another scene because of the Sound Effector inability in setting start/end frames (that's a bad drawback/limitation in C4d), and when I merged the Corona Light with its Xpresso in the new scene again it was not possible to use a Range Mapper with it, it totally didn't work, but something interesting happened!
In fact it was possible to increase or decrease the baked Corona Light intensity by adding it into the Corona LightMix that's a huge benefit of LightMix but from my side there is also a minor drawback, because I myself apply all the lightmix values/setup to the scene before the final rendering in fact I remove all the lightmix passes from MultiPass to decrease the render time but this way and in this case at lease the baked Corona Light pass should exist in the lightmix..
