You can use pitch-class within pattern-map function: (pattern-map '(((0 1 9 4 2 5) (0 4 2 1 9 5)) ((11 8 10 3 7 6) (10 8 11 3 7 6))) '((c6 cs4 a4 e3 d6 f4) (b4 gs3 bb4 eb4 g5 fs6)) :pcs t) => ((c6 e4 d4 cs3 a6 f4) (bb4 gs3 b4 eb4 g5 fs6))

You can use pitch-class within pattern-map function: (pattern-map '(((0 1 9 4 2 5) (0 4 2 1 9 5)) ((11 8 10 3 7 6) (10 8 11 3 7 6))) '((c6 cs4 a4 e3 d6 f4) (b4 gs3 bb4 eb4 g5 fs6)) :pcs t) => ((c6 e4 d4 cs3 a6 f4) (bb4 gs3 b4 eb4 g5 fs6))

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.

Thanks Iviklund. indeed, default articulation is included in my setup from a long time and i forget to put it back here. have a nice day SB

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.

Now, finally it's done by myself. . SB

i did a "default" articulation with no display in my opmo user attributes file. (add-program-attributes '(default) ) SB.
