Support & Troubleshooting

Hello, 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 fou…

Hi all, New to Opusmodus here (really loving it so far!)—two questions: 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. 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 havin…

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

I really appreciate the addition of bind-index in update v4.0.31506 https://opusmodus.com/forums/topic/4133-opusmodus-4031506-update/#comment-14316. This makes reading and comprehending code much easier. Great - thanks @opmo . 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) …

The new .md docu format has a big disadvantage compared to former pdf: 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?

Noobie here. I can't figure out how to make the color choices I'd like permanent in the latest Window version. Any solution would be very welcome. Thanks!

For specific (I guess more significant) OM version updates we find @opmos excellent docu and commentary on what was added and changed in this forum under https://opusmodus.com/forums/forum/4-announcements/. 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) ?

Currently pitch-demix function requires as the first parameter an integer (not a list) which defines the one voice to extract. 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 :pitc…

I would like to use the threading macros, pipeline syntax of arrows package in order to reduce the nesting in LISP code to allow a better readability and understanding (and avoid the alternative repeated reassignment of variables with overwriting multiple times setf). 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 symbo…

Hi, 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/O…

I really like the new layout of the documentation files using markdown. One minor observation is that in dark mode the example code is set against a white background, but the code itself assumes dark mode so the text 'disappears' into the background. This is using dark mode via the System Settings panel. I didn't have any luck attempting to change things using the OpusModus->Settings->Colors panel.

Hi, 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

I updated to the vesion Version 4.0.31331 (4.0.31331) on MacOS. 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?

Hi, 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/Spectra…

Hello, 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

Dear Opusmodus Windows Users 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 !

Dear Windows Users, 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

How can I most easily apply the "AMBITUS function" (or any other) to specific measures? I have an OMN sequence (structured into measures) and would like to apply the function, for example, to measures 24 and 25 and to measure 31, while leaving the rest unchanged. Does anyone have a quick tip on the simplest way to do this? Thx for support André

Is there a function or a way to count how many pitches are present in an omn list . Thank you

Dear All, I received this error trying the last update. Best

Hello everyone, 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

I would like to include some pdf doc the documentation folder of opusmodus in order to access them via the doc folders in the assistant , how may i do it Thanks Patrick

like an automatic gen-dividets (4 4 ) '(1/4 1/8 1/8 1/2 1/4 1/8 1/8 1/2 1/4 1/4 -1/8 1/8 1/8 1/8 1/8 1/4 1/2 1/2 ) maybe this function exist if it does please let me know which one it is ---->. (( 1/4 1/8 1/8 1/4 1/4 ) ( etc .... Thank you Patrick

Now this '(h c4 d4 e4 f4 w g4) results in this. Jesper

Pat_Test.opmo Could you please check this score it seems global-polyphony doesn't work Thank you Patrick Mimran
