Thank you for the code...can't wait to study and tweak example;-) Will await new release with great anticipation

Adding 'swallow' to LENGTH-WEIGHT function would be appreciated here

You've got my attention! Amazing example, thanks

Your "pedagogical examples" ALWAYS worked through and well-appreciated here Stephane, thank you ;-)

Lovely piece Stephane ;-) Fibonacci and Kandinsky, 'these are a few of my favorite things' :) ...

Oh, you are welcome...so glad you both found it interesting/useful :) I have recently been rediscovering it's potentials using MIDI 'Learn'...connecting the 'rotation', pitch values, etc to external LFO's (I use Numerology 4 Pro) makes for some interesting morphing rhythm studies ;-) ...

Hey Julio, I was revisiting some old interests and remembered your post...have you come across these particular related presentations and software? https://theconversation.com/how-a-little-mathematics-can-help-create-some-beautiful-music-61812 http://www.dynamictonality.com/xronomorph.htm ...

Wow! Just installed and ran some examples from your docs...thank you Torsten for sharing this, and all your hard work to document and help install. I will simply echo "lviklund" and say, "This is brilliant!" ;-)

As a novice, I have run into this in my experimentations, and chalked it up to, well...being a novice! ;-) I have imagined it has something to do with having a valid formatting maintained from audition to complete score (given that 'audition' allows direct export to the various formats). And like you, I would suspect it would be the standardized notation requirements..but would be interested to know more (and any workarounds as to 'audition' and thus 'export' options), as the potential of "arbitrary non-regular rhythms" in Opusmodus remains a strong interest of mine for similar reasons as yours ;-)

Eight hours later! Spent all day reviewing related Opusumodus functions/documentation and researching your concepts and references...a very satisfying time in furtherance of my ongoing Opusmodus education ;-) Thanks again Julio for the inspiration, and Janusz for ALREADY including/implementing so many useful tools related to these subjects :)

Thank you very much for taking the time to share ;-) Please feel free to continue to do so as I am most interested in this subject of Timepoint/Rhythm, especially as you apply your research to Opusmodus coding applications/implementations :)

Fantastic,very insightful....thanks for sharing! Visual patterns as compositional approach are one of my interests, as is the idea of organizing rhythm into 'scales' ;-) Please inform if an English translation of main dissertation becomes available (though the excellent illustrations and footnotes in English in current version provide plenty of food for thought as it is, especially as many of your references are on already on my bookshelf ;-))

Pitch-lists are designed for the triggering of Spectrasonics 'Stylus RMX', the mixes then taking three stereo pairs and applying separate fx processing for final bounce in Logic 9.1.8. As I said, pure indulgence of a personal compulsion...shared here simply as example of the variety of Opusmodus application as applied to beat creation. ...

Wow, thank you...that means a lot coming from you :) Even at my extremely novice level with Opusmodus, the possibilities of what I can accomplish towards my own goals (experimental electronics) are seemingly endless :) The combination of the online documentation and the continuing insights/inspiration derived from this forum and it's generous and talented contributors....is making this first leg of my learning Opusmodus an extremely exciting and rewarding period of education...and as I am able generate and collect these audio materials into a personal library, no doubt Opusmodus will allow me to develop unique approaches to electronic musiking which is my primary driving force ;-)

Not much, but happy to share. Somedays, I just set up a live audio host and some interesting instruments and samples, and then 'browse' the Opusmodus documentation. In these sessions, I am combining a playful way to add to my knowledge while generating audio materials via audition and MIDI Export for my library to be used as later combinatory/compound materials. As the title suggests, these are just live experimentations with 'vector-to-length', along with variations on a theme to the value of 'vector-smooth' (from min to max value over session period). ;; (setf vector (gen-white-noise 10000)) (setf v2l-1 (vector-to-length '1/128 -3 13 vector)) (setf v2l-s-1 (vector-to-length '1/128 -3 13 (vector-smooth 0.1 vector))) (setf chromatic-12 '(c2 cs2 d2 ds2 e2 f2 fs2 g2 gs2 a2 as2 b2)) (setf chromatic-16 '(c2 cs2 d2 ds2 e2 f2 fs2 g2 gs2 a2 as2 b2 c3 cs3 d3 ds3)) ;;----------------------------- (setf voice-1 (make-omn :length (length-weight v2l-s-1 :weight '(34 1)) :pitch (span v2l-s-1 chromatic-16) :velocity (messiaen-permutation '(ff f mf mp p)))) ;;----------------------------- ...and with pitch-figurate and additional permutation: (setf voice-1 (make-omn :length (length-weight v2l-s-1 :weight '(67 1)) :pitch (span v2l-s-1 (pitch-figurate 6 chromatic-12 :interval (messiaen-permutation '(1 -1 2 -2 3 -3 4 -4 5 -5)))) :velocity (messiaen-permutation (messiaen-permutation '(ff f mf mp p))))) The pitch list is for the sequential triggering 'sample slices' via New Sonic Arts 'Vice', each slice corresponding to a specific pitch (thus the pitch-figurate serves to add controllable variation of slice triggering). The exercise is focused on rhythm, but in the context of untraditional/non-percussion materials ;-) hth ...
