I've experimented different approach to this in past. One of the possible way is to use passing-interval function to populate between you anchor chords. SB.

I use HARMONIC-PATH function to apply harmony when I want to keep the voice leading of my applied chords. HARMONIC-PATH change totally the harmonic content when applying. TONALITY-MAP just "map" pitches on closest other pitches. Try to use as path some chords with a very typical classical and well defined voice leading with both functions on a more complex material and you will see the difference . S.

Opusmodus as a library sound perfect for me. Opusmodus ltd may sell separately from Opusmodus the library but without asking any fee to developers. I think this will be the best solution, it will increase the sales for Opusmodus and motivate the developers to use Opusmodus as the best platform / library for development of musical applications. Also, it will allow people to use Opusmodus on Linux and Windows. s.

You can use a list of sizes: (harmonic-progression '(1 6 2 5 2) '(c major) :size '(3 3 3 4 3) :base 1) S.

Dear Rangarajan, You can use the :size parameter in the harmonic-progression function to create 4 pitch chords. S.

Yes, it is because the randomness in tonality-map process call randomly the parameter up or down in the :closest option. You can fix this by setting up or down explicitly: (setf path (tonality-series modes :map '(octave) :root roots :closest '(up))) S.

I've tried a bit Ircam instruments2 but still feel a lack of dynamics variety... S.

A possibility is to use plogue Bidule to create a kind of meta-instrument with keyswitch to switch from classical to extended techniques. I will have a look. S.

Hi, yes I have this lib but still not used it really and still not did any soundest for it. But I will investigate in future. Best S.

Hi, The values for density control has to be between something greater than 0, for example 0.01, and 1.00. Here's a better code: (setf size (car (rnd-number 1 12 32))) (setf psets '(c4 fs4 g4 e4 gs4 f4 a4 cs5 ds5 as4 d5 b4)) ;;; RHYTHM (setf dens-tend (vector-round 0.01 1.00 (pitch-to-integer psets))) (setf dens1 (vector-round 0 100 (gen-tendency size dens-tend))) (setf dens2 (vector-round 0 100 (gen-tendency size dens-tend))) (setf dens3 (vector-round 0 100 (gen-tendency size dens-tend))) (setf dens4 (vector-round 0 100 (gen-tendency size dens-tend))) (setf dens5 (vector-round 0 100 (gen-tendency size dens-tend))) (setf dens6 (vector-round 0 100 (gen-tendency size dens-tend))) SB.

Hi, just a small example here about parts extraction with pitch-demix, from piano part to string quartet.

Hi folks, here's the material from this session. Best ! Stéphane auto-explode.lisp auto-split.lisp split-point.lisp Zoom07112020a.opmo ZoomIntoOMVideos071120.zip

Hi, Just added the split-point function who was necessary to run the auto-split function and was missing. Best Stéphane

Move-set is a function inspired by Mikael Kuhn's move-set function in PGen for Csound. https://mikelkuehn.com/index.php/ng It allows you to make random choices by moving progressively in a morphing from one set to another linearly or by following a convex or concave curve controlled by the parameter: curve. <1 = concave, 1 = linear,> 1 = convex. The norep option allows you to remove direct repeats in random choices. ;;;====================================== ;;; MOVE-SET ;;; SB. 01.11.2020 ;;;====================================== ;;; Move-set est une fonction inspirée de la fonction move-set de Mikael Kuhn dans PGen pour Csound. ;;; Elle permet de faire des choix aléatoire en passant progressivement d'un ensemble à un autre ;;; de manière linéaire ou alors en suivant une courbe convexe ou concave controlée par le ;;; parametre :curve. <1 = concave, 1 = lineaire, >1 = convexe. ;;; l'option norep permet d'éviter les répétitions directes dans les choix aléatoires. ;;; Parametres: ;;; set1 liste ;;; set2 liste ;;; nbsteps entier ;;; nbval entier ou liste d'entiers ;;; curve <1 = concave, 1 = lineaire, >1 = convexe.

Yes Musescore is very interesting indeed. It sounds a bit different in Sibelius but it is exactly the same VSL instrument hosted in Vienna Ensemble Pro but my OM soundset is a bit different than my Sibelius one , indeed. Best Stéphane

SoloCelloExempl.mp4 As you can see , I don't need any extra staves to have key switch . All the best Stéphane

But I'm speaking about Musicxml. S. One moment, I'm doing a video. S.

The problem comes from Musescore because it have no soundest and by the way don't send any key switch to instruments. I'm working with Sibelius, and I just need to open the xml file in Sibelius and it plays immediately all articulations. Stéphane
