Ok, we don't 'get' each other.
I use the band in a box 'app' where you go in and identify which midi channel you want to export to and it does the work.
I forgot you are using Realband and have to wrap the cords on your own.
I do understand yer root position, and in a pinch to force a walking bass use slash chords, but I've never sat down with the midi on ch 5 and dissected it. Some day when I'm bored.
It sounds like calculus to me thus it's to be avoided like Miss Smith's grade 12 calculus course at TabbaccyHigh.
