Support & Troubleshooting

Hello, I was just going through the Per Norgard tone-lakes function. When I just tried running one of the sample codes in the information about it, I am able to general omn out of the code, but when I select anything under " Evaluate Score", none of the options yield anything. I also get the error pasted below. I assume this is connected to some error I might have down when installing my Opusmodus 4.0 upgrade, but I don't really know what the problem is. Here is the code snippet I used: (tone-lakes 108 '(0 -14 -7) nil '(g5 eb4 a4 cs5) 'chromatic '(p i ri r) :imethod 'wrap :iambitus '(c4 b5)) Here is the error: OM 1 > tone-lakes (g5 e5 d5 bb4 f4 b5 fs4 d4 c5 a4 …

Hello, I am a little rusty in all things Opusmodus, and am getting back into it, especially with the 4.0 upgrade. I purchased the license, and installed the upgrade, but now I noticed I cannot get any sounds out of Opusmodus whenever I try auditioning anything. The window that opens up (and usually disappears a few seconds after starting Opusmodus) doesn't shut down, even though it says "2 seconds remaining"). I went through the Opusmodus folders and saw the following error. This error comes after I tried going through the CLM Read Me file. This the error I'm dealing with. I'd appreciate any help I can get on this so that I could begin working with Opusmodus again. Than…

What is the CLM Installation procedure for Windows? I have a new install of Opusmodus 3.0 on Windows 10 Pro. Any insight is appreciated. Many thanks!

Hi all — I’m trying to better understand how to switch MIDI output back to internal sounds in Opusmodus after routing to Kontakt via the ‘IAC Bus 1.’ What’s the correct way to reset the output to internal, either in the score layout or sound set? And what is the best way to Would be nice to see an easier way to navigate the midi routing in a future update. @opmo Also I appreciate you adding the 8 string lay-out. However, I am still unclear as to what that does or how to use it. That said perhaps we can add a 9 string version that responds to midi from C#1 to e6? Thanks

Would have been nice to include the upgrade in the sale? (but no surprise you didn't) In my humble opinion Opusmodus is way overpriced and always has been. I would have upgraded to the latest version a long time ago if you made it accessible to mere mortals in the real world i.e not academics Just my feedback.

Hello everyone, Unfortunately, I am unable to install version 3 of Opusmodus (I’m attaching screenshots). I tried Opusmodus 4, but after the trial period ended, I attempted to revert to version 3. Please note that I uninstalled everything and tried reinstalling version 3, but without success. Can anyone help me? Thank you very much.

The workflow with importing/exporting MusicXML is really great—it opens up a whole new way of working. Congratulations and thanks to Janusz and the OPMO team! Greetings André

I can't open the documentation inside Opusmodus in Windows 11. Don't know why. Do I need to have edge installed ? Thanks,

Hi! I'm encountering a notation glitch/issue that I just can't nail down. I have a function (assign-registers) that assigns a list of pitch-classes to different registers. My goal is to notate them as chords on a Piano Staff as whole-notes. The chords should not have any octave duplications, and in this case should all have eight notes. To illustrate that, I've added a format statement that shows both the list of chords created by the (pitch-transpose -24 (chordize pitch-list))) as well as the original untrnsposed list of pitches. [Note: The OpusModus forum interface wants to consume the asterisks (*) in my variable names. The variables are correct regardless of the actu…

Subject: Setting MIDI output ("Bus 1") on Mac M3 Body:

Hello, I'm a new user and wondering if there is a recommended method to input and convert a score to OpusModus. I have a score I've written in 4 parts each part represented in its own file in both MusicXML and MIDI. My goal is to import (either the MIDI or MusicXML) and convert these to OMN so that I can modify them using functions. I have been able to import them but I'm having difficulty converting them to OMN and I haven't been able to find this specific use case in any of the documentation. Any best practice or advice is appreciated. Regards, Tom

Hi all, I'm new to both Opusmodus and just intonation. I'm working through the book "The Arithmetic of Listening" by Kyle Gann, and interested in exploring these topics in Opusmodus. I see the command for ratio-to-cent (documentation excerpt pasted below) which gets me part of the way to what I'm interested in, but what if I want to actually here this scale? Or tune my music to match this scale? I think I can understand how to build out any just intonation scale, but just not sure how to actually hear and write music using the scale. Any advice?

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 ?

I’m trying to merge two voices, but the grace notes get lost in the process. What do I need to do differently? Thanks for any advice!

Hi, I have experimented with tonality-map and harmonic-path, and I have a simpler problem I think, but let me know if I should still be using the previous to solve this problem? Thinking like a guitar player, I want to play a pattern from a series of chords based on the note order within the chord. 1st note, 2nd note, 3rd note. For example say I have chord c4e4g4, and I have a picking pattern that goes (e c4 e4 c4 q e4g4 e c4 e4 c4) this is choosing notes in an order of ( e 1 2 1 q 23 e 1 2 1) Now the next chord has notes (a3e4a4) which would result in (e a3 e4 a3 q e4a4 e a3 e4 a3) following note order within the chord of ( e 1 2 1 q 23 e 1 2 1) I would like to appl…

Hi everyone, I have an idea for a piece where I generarte motivic material then map it contrapuntally to the chord progression of John Coltrane's "Giant Steps" For example, let's say I have Coltrane's classic motif (e c4 d4 e4 g4 ) and I manipulate it with inversion, retrograde, randomization, etc. How can I then apply, or map that material to the chords? Same for a 16-measure melodic structure made up of multiple generated motifs. How would I map such a melody? I have input the progression as such: (setf StepsChords '(((h (b3 maj7) (d3 7) ) ((g3 maj7) (bb3 7)) ( w (eb3 maj7) ) ( h (a3 m7) (d3 7)) ( (g3 maj7) (bb3 7)…

I'm running into a recurring and confusing issue in Opusmodus and would really appreciate your help. I work with a folder structure where each folder is dedicated to a compositional theme (e.g., melodic counterpoint ideas). Inside these folders, I create many uniquely named .opmo files as I experiment. Once I'm satisfied with a file, I save and lock it to preserve its state. However, after restarting Opusmodus, I consistently receive a set of confusing prompts, such as: "File has changed on disk and you have made changes too. Read in disk version of ...?" I usually select “No”, assuming I haven’t saved a newer version elsewhere. Then I get: "Do you want your changes saved…

if i use chat gpt from opusmodus, we cannot copy paste from within the page, and from one window to another. If i use chat gpt from a browser outside of opusmodus it works. It would be nice to fix this problem Thank you Patrick

I want to map a melody over chords taking into consideration both of their durations. (setf motif '(s b3 b3 b3 b3 b3 b3 b3 b3 b3 b3 b3 b3 b3 b3 b3 b3)) (setf chords '(q c3e3g3 d3f3a3 h g3b3d3)) (setf map-1 (harmonic-path chords motif)) yet I get (s c3 e3 g3 d3 f3 a3 g3 b3 d3 c3 e3 g3 d3 f3 a3 g3) I find that no matter what notes I put in motif, I always get the same result which is just the 9 chord notes being arppegiated 16 times in sequence. Ideally I would like the notes of motif, to find it's closest match in the chord.

Hello, using pitch-transpose i sometimes get unexpected results with pitches as transpose value. the results are one octave lower than expected. Here are examples: (pitch-transpose 'd3 '(c3 d3 e3 f3)) -> (d2 e2 fs2 g2) (pitch-transpose 'd2 '(c3 d3 e3 f3)) -> (d1 e1 fs1 g1) (pitch-transpose 'd4 '(c3 d3 e3 f3)) -> (d3 e3 fs3 g3) interestingly, this one works as expected: (pitch-transpose 'd5 '(c4 d4 e4 f4)) -> (d5 e5 fs5 g5) What am i missing?

Hi, Using diatonic-chord Is there a work around to be able to omit 3rd from a chord, as I don't see any defined explicitly with omit 3rd. Are all the chords defined somewhere accessible that I could add more? thanks
