And care must be taken, as many of the updates released for Catalina notarization compatibility are now broken under 10.9.5. Apparently, certain combinations of code are ok, but at least as far as audio apps and plug-ins...9 out of 10 updates no longer run on my machine. I am told 10.11 is minimum, but several developers (like Zynaptiq) are able to maintain 10.9.5 compatibility...so it is possible, at least with their framework. And again, my experience is mainly coming from audio plug-ins compiled for Catalina that did work previously on Mavericks, and now don't. Not sure what, if any, of this affects the compiling of code for an app like Opusmodus?

No '13' or '19'? I find the Ulam Prime Spirals and Abarim 'Pillars' to also produce interesting polyrhythms:)

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. ...
