Thanks for the Blog Noel. Very interesting and I now have a much better idea of how R-Mix can be useful. Still a bit advanced for me, but very educational!
Glad you found it useful. To clarify, for normal use when you have a single voice that you want to modify in a mix, its actually very easy to use Rmix. All you do is pick a shape elliptical or rectangular) and use that to isolate the voice. Then you use the 2 sliders to boost that voice alone or the "outside". And then the pan to place the voice in the stereo image.
The case where it gets a bit more tricky is when you want to handle multiple voices in the same mix independently (as was the case here) Then you have to have a bunch of Rmix instances in series with each independently manipulating a voice. With that power comes some complexity.
