Don't take anything that follows as official PG music fact. It very well could be that my ears are fooling me...but:

I seem to sometimes experience when adding a "slash" note that is actually in the basic triad that some of the main instrument RT's are gently persuaded (if not actually forced) to play in the associated inversion.

For instance, a track playing a C chord with a slash note of E SEEMS to me to be playing a C chord in first inversion, putting the "C" at the top. The same may be happening with a G on the bottom, putting E on top. I haven't tried enough RT's to thoroughly test this out, but it sure often seems that way to my less-than-trained ears.

Regardless, RT's are audio and what will actually "play" depends on what was recorded, and how it is "brought up" by the program. As such, you can't MAKE it happen with RT's, but regeneration and/or multi-riffs will give you as much variety as possible.
