Is there a user-option to switch it back to english?

New to Opusmodus here (really loving it so far!)—two questions:

1. I'm working on a project where I am sending MIDI from Opusmodus to Supercollider via an IAC port. I've noticed that the more I use Opusmodus, the slower performance becomes, particularly when playing back notated material but also when typing in the IDE and processing functions. Upon restarting Opusmodus, the issue is fixed, but it seems to need a restart every hour or two. I have been interrupting the listener and stopping audition to try to clear anything holding on in the system.

2. As I've been learning, I've been opening a lot of help files (not sure if this is connected with the issues I'm having in #1, but the issue persists even after I close the files). When I press command-D to view the documentation for a given function, it leaves the file I was working on to open the help file in the same assistant window. Then, when I press the back arrow at the top left, it doesn't take me back to the project I was working on, but whichever help file I looked at before that. Usually there's a long list of recents that I have to sift through to get to the file again. Is there a shortcut to open documentation in another tab? It's not a huge deal; I can just keep another assistant window open, but it'd be good to know if there is another way.

   
   Best,

Hello, on my Windows 11 version multilingual, the score/sheet music display has disappeared from all my files, and an error is being reported. I tested this using the example scores from the wizard. However, the "MIDI" display does launch correctly. When I run "Evaluate Score," the following message appears: "Type :bug-form "<subject>" for a bug report template or :? for other options."

And when I search for the score viewer in the assistant, this message appears: "Failed to load the SeeScore library for Notation with error Could not register handle for external module #P"C:/Program Files/Opusmodus/bin/SeeScoreLib.dll" : The specified module could not be found."

I am very frustrated because I am working on an important project. Is it possible to download the previous version of Opusmodus so that I can work? Thanks in advance.

Amitiés.

Didier

Hi, all

THis snippet apears as sextuplets in the notation viewer but opens as triplets in Musescore, after open in external editor

((6q gs3 cs4 eb4 b3 cs4 gs3 cs4 b3 gs4 e4 b3 cs4)

(6q f3 bb3 cs4 g3 bb3 f3 bb3 gs3 f4 b3 bb3 f3)

(6q eb4 e3 bb3 eb4 fs4 b3 f4 fs3 g3 f4 gs4 e4))

something strange...

Im in the version 4.0.31480

Question:

@opmo Can bind-index be modified, such that the arrows feature described below is mimicked?

This would make code even cleaner (at least in case of functions where x is in first argument position.

;; New syntax v4.0.31506
;; Example from https://opusmodus.com/forums/topic/4133-opusmodus-4031506-update/#comment-14316
(bind-index 'mat
  (gen-noise 8 :seed 42)
  (vector-smooth 0.3 x)
  (vector-to-pitch '(c3 c5) x)
  (pitch-transpose 12 x)
  (tonality-map '(major :map 'octave) x)
  (make-omn :pitch x
            :length '(h)
            :span :pitch))
; => (h g4 mf g4 f4 c4 a4 f5 a5 c6)

;; Compare with arrows
(-<>
 (gen-noise 8 :seed 42)
 (vector-smooth 0.3 <>)
 (vector-to-pitch '(c3 c5) <>)
 (pitch-transpose 12 <>)
 (tonality-map '(major :map 'octave) <>)
 (make-omn :pitch <>
           :length '(h)
           :span :pitch))
; => (h g4 mf g4 f4 c4 a4 f5 a5 c6)

;; Summary:
;; bind-index is functionally equivalent to original arrows-syntax :-)
;; except for the fact that bind-index is more powerful
;; as one can refer to an explicite intermediate pipeline result.


;;; ---------------------


;; But there's one feature which has yet not been 
;; carried over from arrows to bind-index
;;
;; arrows has a feature where former pipeline result
;; is implicitely added even if <> is not meantioned
;; this works for functions where <> has 1st argument position

(-<>
 (gen-noise 4 :seed 42)
 (gen-divide 2 <>)
 (flatten)) ;; no x here
; => (0.45572352 0.3392996 0.19626139 0.81495554)

(bind-index 'x-
 (gen-noise 4 :seed 42)
 (gen-divide 2 x)
 (flatten)) ;; no x here
; => throghs an error as x is missing

(bind-index 'x-
 (gen-noise 4 :seed 42)
 (gen-divide 2 x)
 (flatten x)) ;; x included and required currently
; => works
; => (0.45572352 0.3392996 0.19626139 0.81495554)

I often study OM function docu on my iPad when I am off from my OM-computer (not in creative rather learning mode). In the past with pdf it was very educational to see code examples with results of evaluation. Now with .md I can only study the function call (using a md-reader) but I am lacking computation on iPad I do not see the evaluation result. This is not optimal to learn OM.

Not sure how many users do something similar.

Is there a way to get evaluation included with docu?

For other updates (example 4.0.31472 from today) I am not aware where to read this up.

Is there a place inside OM or outside where we can find changelogs for each new version update (even if rather insignificant) ?

Is there a way to extract more than one voice from a chord at once (example: extract 3rd, 5th & 7th of chord at once), by applying a list of integers at once?

This would be great for orchestration to define which pitch of a chord goes into which strata..

;; Define chords
(setf chords (-<> 
              '((c4 maj7)
                (a3 m7)
                (d4 m7)
                (g3 7 ))
              (expand-chord <>)
              (make-omn :pitch <>
                        :length '(w)
                        :span :pitch)
              ))
; => (w c4e4g4b4 mf a3c4e4g4 d4f4a4c5 g3b3d4f4)
; works as expected :-)


;; Extract root
(setf bass (-<>
            chords
            (pitch-demix 1 <> :sort nil)
            (pitch-transpose -24 <>)
            ))
;=> (w c2 a1 d2 g1)
; works as expected :-)


;; Extract 3rd, 5th & 7th at once
(setf harmo (-<>
             chords
             (pitch-demix '(2 3 4) <> :sort nil)))
;=> (w e4 mf c4 f4 b3)
;
; not as expected:
; expected is: (w e4g4b4 mf c4e4g4 f4a4c5 b3d4f4)


; alternative try with nested list:
(setf harmo (-<>
             chords
             (pitch-demix '((2 3 4)) <> :sort nil)))
; error


; 2nd alternative try:
(setf harmo (-<>
             (list
              (pitch-demix 2 chords :sort nil)
              (pitch-demix 3 chords :sort nil)
              (pitch-demix 4 chords :sort nil)
              )
             (pitch-mix <>)
             ))

;=> (d. e4g4b4 c4e4g4 f4a4c5 b3d4f4)
; close but not correct, see length


; 3rd try:
(setf harmo (-<>
             (list
              (pitch-demix 2 chords :sort nil)
              (pitch-demix 3 chords :sort nil)
              (pitch-demix 4 chords :sort nil)
              )
             (pitch-mix <>)
             (length-diminution 3 <>)
             ))
;=> (w e4g4b4 c4e4g4 f4a4c5 b3d4f4)
; OK
; But very involved and fragile
; Can this be done easier by accepting chord-specific list inside pitch-demix function ?

I think often we have chained operations using OMs functions (see example) where the arrow syntax in my personal view is helpful to understand the step-by-step computation, simply reading from top to bottom and holds the steps still in compact form which increases comprehension.

https://quickdocs.org/arrows

I can use it in OM but need to use namespace in front of the arrow.

I cannot import the arrow symbol ->> (same for ->) into OM, see error message in comment of code block.

Any help ?

Can we use the arrows in OM directly ?

(asdf:load-system :arrows)


;; Test works, but only by prepending namespace before the symbol, which is tedious
(setf var
      (arrows:->> 
       (gen-noise 8)
       (vector-smooth 0.3)
       (vector-to-pitch '(c3 c5))
       ))
=> (d3 d3 a3 c3 d4 c5 b4 c5)


;; Trying to import the ->> symbol fails.
(import 'arrows:->>)
=>
Error: Importing this symbol into the OPUSMODUS package causes a name conflict: ->>.
  1 (continue) Unintern these symbols and try again
  2 Skip importing these symbols.
  3 (abort) Return to top loop level 0.
    

Sorry, me again.

In trying to understand the new and very comprehensive Analysis section I note that the examples in the documentation start with the expression:

(setf webern5 (musicxml-to-omn "webern-op.5.xml" :inst 1))

Unfortunately that file does not appear to be in the standard search list and I'm getting 'file not found' messages. There is a file Webern-Op.5.xml hidden deep in the documentation but changing to use that case still does not find the file. Ideally, it should be possible to run the examples in sequence and see the results in the console which is very useful to learn new packages. (If I give a full path (setf webern5 (musicxml-to-omn "/Applications/Opusmodus.app/Contents/Resources/English.lproj/user.omdocset/Opusmodus/Media/MusicXML/Webern/Webern-Op.5.xml"))to the file hidden in the docs folder it does work) - but to get the next example in expressive-analysis (for example) only works if I wrap the result in an mcflatten call. e.g.:

(setf webern5 (mcflatten (musicxml-to-omn "/Applications/Opusmodus.app/Contents/Resources/English.lproj/user.omdocset/Opusmodus/Media/MusicXML/Webern/Webern-Op.5.xml")))

Then following examples work

I'd like to change the behaviour of the editor so that files reload automatically when they change on disk and not after responding to a dialog box.

Is this possible?

Many thanks,

Pete

The system funtions seem to be documented in a format mix of mardown and pdf.

Any reasons for keeping pdf, i.e. gen-tuplet or is it just transitional?

Quick (and possibly simplistic question). I've been using the ChatGPT window successfully in OpusModus but find that keeping track of what needs to be cut and paste becomes challenging on larger projects. I've used Codex in other languages for its agentic capabilities and am stuck on how to give Codex access to the OpusModus documentation files so it can create more OM focused coding similar to way the OM ChatGPT window does. Of course they may be hidden for a reason but the OM ChatGPT says:

The Opusmodus documentation files available in this session are stored under /mnt/data/.

Examples:

• Main manual: /mnt/data/Opusmodus Manual.pdf

• Spectral manual: /mnt/data/Spectral Analysis Manual.pdf

• Ncode manual: /mnt/data/Ncode Manual.pdf

• CLM guide: /mnt/data/CLM-Opusmodus-Guide.md

There are also related Opusmodus knowledge files in the same folder, such as /mnt/data/Opusmodus_Functions.json and /mnt/data/Opusmodus_Functions_Listing.json

and I can't find that directory.

Any suggestions would be much appreciated

Pete

I´d like to create an easier shortcut for midi input, with less keytrokes, because for typing "ctr+shift + m" I need my 2 hands. If I could make an easier shortcut, like shift + m, I could be with one hand at the midi keyboard and other at the computer keyboard.

Please, any help ?

Best,

Julio

I can´t use here the CLM functions (with audio instrumentos and functions).

Are you having trouble with this in Windows 11 ?

I can run sound samples like in the post below, buto no success with CLM.

Any help or comments ? Thanks !

After the Windows 11 26200.7840 Security Update (February 11th 2026), the virtual ports are not showing in windows, only the hardware ones.
At first I though it was related to Opusmodus update, but it´s a windows update BUG.

Here is the solution.

• Close all MIDI apps

• Open Windows Terminal as an Administrator (“run as administrator”)

• Type "net stop midisrv"

• After that completes, type "net start midisrv"

• Start up the app you want to use with MIDI
  

Here is a video:

Best, Julio

Thx for support

André

Thank you

I received this error trying the last update. Best

I recently started using OM 4 and I’ve noticed some unusual behavior in the graphical displays (all graph types).

I tried reproducing the same procedures shown in online examples, but the results are consistently different. I’m attaching screenshots for reference.

I’m not sure whether this could be related to a Windows setting or if the software itself is rendering the graphs differently.

Has anyone experienced something similar or knows what might be causing this?

Thanks

Thanks

Patrick

Thank you
