As far as I remember, super midi tracks were created by real musicians using midi instruments.

I don't see what "voice leading" or lydian chords have to do with it. (Whatever they are...)

May be you want BIAB to be more scientific, but it is first and foremost a simple way to create music to play along with.

But back to the original issue we do need a way to edit the super midi tracks.
