Made In Opusmodus

Here is a function (with subfunctions) that operates based on the principle of the Brownian bridge. You define the start and end, and with each generation, an extended embellishment emerges. The principle is simple and allows for the creation of ornaments. Attached are some examples — I’ve structured them this way to make the principle easier to understand. Here is a small graphical model showing four generations. The start and end points remain the same, while new random points are added in between with each generation.

Happy New Year 2026 to OM community.

Dear Friends at Opusmodus team, With great joy, I´d like to share with you an important international prize I received as composer in 28th november. It´s the IBERMÚSICAS prize for Symphonic Band 2025. It was very competitive and I´m honored to represent Brazil in this contest. I´m posting this here because Opusmodus became since 2017 a very important tool in my compositional process, although I do not use it from beginning to end, i.e., there are many things I do manually. Nevertheless, it plays a crucial role in my workflow and I´d like to thanks the team for this. All the best and happy 2026 ! Here are the selected compositions: https://seleccionados2025.ibermusicas…

Followup on post: https://opusmodus.com/forums/topic/3989-om-lydian-chromatic-concept-of-tonal-organization-george-russell/ Here's another a bit more involved attempt using LCCOTO for my naive take of a fusion piece. The chord track for 2 parts is given, melodies use the LCCOTO parent scale for chords. One can exchange by other more outgoing scales. Audio example are for normal, most ingoing lydian scale. Code for the function find-parent-scale-for-chord is this post 3 picked audio manifestations with different start seeds. Seed: 78641 e1.mp3 Seed: 34987 e2.mp3 Seed: 10461 e3.mp3 Here's the code.

Code for the function find-chord-for-parent-scale is this post. Would be great to have a scale like lydian-chromatic (c1 g1 d2 a2 e3 b3 fs4 gs4 eb5 bb5 f6 cs7) properly built into OM (respecting the order of pitches, which is important for LCCOTO). Maybe with a reference to Russell as this seems to be a tradition in OM (Modes.opmo). The OM built-in scale chromatic-lydian with similar name seems to be 7-pitch scale (c4 cs4 e4 f4 fs4 a4…

Hi folks, Opusmodus is really amazing for music production. Here’s a short orchestral test I’ve made today, the rendering is Sibelius and NotePerformer. NewOrchestralAlgoTest1NP.mp3

Dear Opmo friends, I’m sharing a short SATB piece together with its score code and MP3 file. Hope you’ll find it inspiring and enjoyable! Best, Stéphane Score240-SATB.mp3 Score240_SATB.opmo Score240_raw_OMPrintScore.pdf

Hi folks, I’d like to share a brief experimental study for a String Quartet based on an FM spectrum. It is basically a test of VSL Solo Strings Studio’s microtonal capabilities with no real attempt to be musically developed or interesting. However, it also serves as a test for my workflow with Lilypond. Unfortunately, actually, even if I own Synchron Solo strings, I don't use them because the Sul Ponte and Sul Tasto are still not implemented in this new lib, so I continue to use the VSL Solo Strings studio version. But microtonality works very well ! Best Stéphane MicroStud-S237-858649.mp3 Micro Stud S237-858649.pdf

Hi Folks ! Sadly, Barry Vercoe, the creator of Csound, passed away one week ago. I've played a lot last week with Csound (I love Csound!) trying to build a cool workflow within Opusmodus for algo comp with Csound based on a premade instruments library I’ve started to build. This allows me to focus on music when composing in Opusmodus with Csound. Here are my first tests. Csound-Def-Csound-score-Experiments.mp4

One more small (improved) function: a starting rhythm (pattern) gradually changes its values towards a constant pulse/value (endvalue). Other possible applications: An initial pitch sequence evolves into a steady, constant pitch. A start pattern for velocity gradually shifts towards a fixed velocity.

Real-Time Pitch Memory: Compositional Feedback System Using MaxMSP and OPUSMODUS This text outlines a specific aspect of a larger project I am developing for live electronics and instruments. Since the work heavily involves live electronic processing in real time, it is based on a MaxMSP patch that I am currently building. An important component of this system involves integrating OPUSMODUS for certain compositional processes—specifically, the processing of pitch material collected in real time via a pitch follower from an improvising musician. In MaxMSP, this means that every few seconds, the most recently played pitches (as MIDI note numbers) are saved into a .txt fi…

I am currently learning Max MSP for a project, but I would like to use a part of computing structures that I can generate much easier in Opusmodus. So I write code in OM (sorting algorithms for some clicks), test it (and modify my code), then export it to a library in Max MSP. I can now call up/coordinate the MIDI files in realtime etc ... in Max MSP. (Workflow as a beginner in Max MSP...) Bildschirmaufnahme 2024-11-01 um 11.13.28.mov
