I have understood that I am not the only one struggling to understanding iterations, still after using Open Music since the Patch Work days.

It would have been great if someone could give some hints, or program the algorithm, where the chord sequence can be looped to fit the length of the transposition row.
My Norwegian colleague Anders Vinjar, said to me, that he programs the controls as Lisp code, and not using the visual functions which I am dependent on. Furthermore me talking about my lack of arithmetic skills, he stressed that it is not about mathematics, but logic.
Ruben Gjertsen - also a colleague from Norway - and I have been talking about superimposing loops of different lengths and parameters, and today preparing this post, I stumbled upon the following post.
CNMAT-OM OPENMUSIC LIBRARY RELEASED (August 15, 2017) might be a sollution, but some help will be appreciated just to understand how to use iterations.
