That is exactly how it works. I chord is at toe-up, II chord at mid position, V chord at toe-down. It took a lot of working out to get it to work as you aren't working with actual pitches, but rather with offsets from the root note, which is shifting. That would be quite straightforward if you want the same overall chord shape on all three chords, (by that I mean, eg. the third is always the lowest note, ninth always the highest etc.). I was trying to achieve smooth internal voice lead
