Great ! i will be fan of this function ! S.

As an alternative solution, You may use Torsten Anders's preview-score function for doing what you want: SB.

I agree at 100% !!! Would be good to share this advice on social media etc... 😉 S.

Here is one of my Logic X template for working with Opusmodus. 16MidiInInstrTemplate.zip

Personally, i like very much to use the loop macro facilities, much clear and easy for me than recursion. Also, I am a big fan of it because it is very powerful. SB.

(make-omn :pitch '((c4 d4 e4 f4 g4)) :length '((s s s s q)) :articulation '((num1 num2 num3 num4 num5)) ) S.

Here's a small Prelude for Piano. SB.

Hi Julio that score use the pcs 7-33 as pitch material. It use also a vector mapping on "reservoirs" of motives for the music generation. All this was done on the fly on a draft file. Once done, i've used pprint for pprint the score on my finale opmo score file and add some few treatment for creating the coda. Score attached to this post. All the best S. prelpia171218.opmo

May be Expansion-series functions pitch-repeat-transpose (re-incarnation 🙂 trim with gen-trim length-diminution or augmentation fragmentation with pitch-fragment gen-transition or gen-morph etc.. use weighted function to add more and more rest in music (length-weight) use text-to-pitch functions to create pitch structures based on the Death word or a death poem create vectors who go from top to bottom (or reverse) and use them for rhythm, pitch etc... (gen-tendency) the possibilities are endless 🙂 SB.

originally, i've made gen-chord3 with JP for using in this top to bottom approach. what is called root in gen-chord3 parameters was not thinked by me originaly as "root" but more cantus note on with to add other notes (below or not). S. But naturally, the gen-chord3 function is not conditionnal, so we have to think about something else but i think you can do that with pattern-match function. S. or also with def-case.

(gen-retrograde durations1 :omn t) => ((t s t) (t 13/96 3q) (5h = 3/35 7q = = = = 3/35 5h =) (3q 13/96 t) (t s t)) S.

For span-ignore-pause, use the function gen-swallow SB.

You may use text attributes. S.

But indeed, i see, it is more about chord processing... Thanks for this. All the best SB.

But also you need to use the :cycle t keyword. It allo you to cycle between the chords definition, because if :cycle nil (default) chords are chosen randomly. SB.
