Maybe this will help
take a simple chord progression
dm, c6, bflat6, fmaj7

look at how strings are voiced
each chord gets voiced with parallel voice leading

there is no counterpoint (contrary motion, oblique motion)
I didn't check every style, I am using elegant slow pop

I thought MIDI could make wiser decisions, based on counterpoint rules
