Hello everybody!
I’m researching again a little bit on L-Systems / Lindenmayer Systems and i was wondering what your experiences with these are?
Espacially in Csound. May it Sound Generation, Sound Control oder Data creation.
I was using L-Systems via Common Lisp and i wanted to connect it a little deeper to Csound and i want to see whats it’s possible there.
All the Best
Philipp

I have been using a variety of Lindenmayer systems, implemented by me in a variety of programming languages, to compose pieces for Csound, over the past 30 some years. These days, I use L-systems that I have implemented in C++, Python, and JavaScript. One feature of some of my systems is that they use neo-Riemannian chord transformations and/or tonal scales to generate not only notes, but also harmonies. The source code for systems that I currently maintain is here: A few examples of music that I have composed using L-systems: Source code for many of my pieces is here: Regards, Mike ----------------------------------------------------- Michael GoginsIrreducible Productions http://michaelgogins.tumblr.com Michael dot Gogins at gmail dot com On Fri, Feb 21, 2025 at 8:21 AM Philipp Neumann <0000119f78f3a4f9-dmarc-request@listserv.heanet.ie> wrote: Hello everybody! |

Fun that you should ask... I was working on a midi-controllable Lsys generator in Csound today. I have been using the,m in the past, but never got around to really making anything with them. I do include them in my digital composition class, though, and this year actually several of the students picked up the ideas. Then I thought I'd look once more for myself too ;-) The midi controllable one is very much an odd attempt and needs much refining. I'll share when it is presentable. I attach two examples I have used in class that just shows a possible way to implement them in pure Csound. I use recursive instrument calls to produce each generation. That is a little bit messy, but perhaps you find it useful ;-) Øyvind fre. 21. feb. 2025 kl. 08:21 skrev Philipp Neumann <0000119f78f3a4f9-dmarc-request@listserv.heanet.ie>: Hello everybody! |

Mike -
I find your sounds and textures in "Poustinia Variation 5a" both beautiful and fascinating.
If they were made in Csound, I'd love to see their instrument design.

I'm glad you liked it! The entire piece is defined in this one file, including the Csound orchestra: The orchestra in this piece uses some of these "patches," one per Csound instrument definition: These patches are designed to be used according to this scheme: In fact, all of my pieces for the past 20 or so years are available as open source on GitHub, mostly here: Best, Mike ----------------------------------------------------- Michael GoginsIrreducible Productions http://michaelgogins.tumblr.com Michael dot Gogins at gmail dot com On Fri, Feb 21, 2025 at 4:55 PM Arthur Hunkins <000001e1d761dea2-dmarc-request@listserv.heanet.ie> wrote:
