Middle-line stem direction

[OCTO]

operate on a "higher level" than our standard ones. They tend think in large numbers of tones when assigning stem direction

What an excellent observation. Being a composer myself, I tend as well to "adjust" my scores in a way that breaks the standard rules, with my inner purpose.
Looking forward to this topic!

Thanks, OCTO.!

I think that there is actually a set of rules that they are following, because, having worked with this material for a while, I can very often predict the non-standard stem directions that they will use.
