Hello, After several years developing advanced compositional systems and tools in Opusmodus (generators, density engines, microtonality, algorithmic orchestration, Csound/Max integration…), I’m opening a few private consulting slots. I offer focused 1:1 support for: — compositional engine design — procedural generative / stochastic / constraint systems — formal algorithmic structures — custom libraries and tools — workflow automation — finishing and polishing pieces/scores Sessions are practical and project-based, working directly on your code and music. Limited availability to ensure high quality mentoring. Feel free to contact me privately. Stéphane Boussuge ComposerWorkshop

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

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

Dear @Stephane Boussuge , In your YouTube video https://youtu.be/YiniUvDrvIw?si=Lz-p2ncP4_SeddS3 you shared a trick to nicely interact in a light way with Ableton by dragging OM-exported midi to session view. You also show to use IAC in preview-score. My question refers to the iac instrument set. Would you mind to share the code of your iac instrument set ?

Hi dear Opusmodus friends, Here’s a new video from the series: Opusmodus in 3 mn. That one is a quick show of the musicxml import. -
I’m writing a piece for flute, oboe clarinet using infinity series and I get the following error: <<automatic abort>> OM 6 > infinity-series gen-repeat gen-repeat flatten infinity-series gen-repeat gen-repeat flatten infinity-series gen-repeat gen-repeat flatten ps Error: OMN Parse Error: fail 1 (abort) Return to top loop level 0.

Hi Stephane Based on your example i tried to apply a transposition list based on your functions but with an exotic scale Ex ;; degree selection (setf degr '(1 4 2 5 1 6 4 2 5)) ;; remove 1 from each degree for use as transposition ;; inside tonality for diatonic transposition (setf trsp (mapcar (lambda(x) (- x 1)) degr)) ;;; some material (setf arps1 (gen-repeat (length degr) '((s c4 e4 g4 c5 e5 g5 c6 g5 e5 c5 g4 e4)))) ;; apply diatonic transposition (inside tonality) (setf arps.map (tonality-map '(hyojo :root c4) (pitch-transpose trsp arps1))) This is the start of the result i gat with pitches not belonging to the scale (s c4 f4 g4 c5 eb5 g5 c6 g5 f5 c5 g4 f4) (s eb4 g4 bb4 eb5 g5 bb5 eb6 bb5 g5 eb5 bb4 g4) i think the trsp function doesn't work with the Hyojo scale . Is there a way to make a algorithm which would work with any type of exotic scales ? Thanks Patrick
