Support & Troubleshooting

Hello I'm new here. I'm on the demo and doing fine but for the life of me I can't figure out what the n integer does after :seed? I know seed fixes a random function so it is repeatable but what does that number do? I tried changing it in Tutorial 5 but I can't make sense of it! Thanks Andy

Hi I'm starting to loose the will to progress. So I just spent an hour trying to evaluate this and getting errors and thinking I'd got the wrong number of brackets and yet it looks fine. (setf motifx12 (rnd-order (gen-repeat 12 (list motif)))) :seed3) And then I realise that I have to place the cursor not on the final bracket but on the one before :seed3) Nowhere does it say this in the manual as far as I can tell. And why? I think it's something to do with the : colon that I don't understand in the language. And I still don't understand seed. I'm really trying to get to grips with lisp but my hair is on fire. 😞

Is it necessary at all to do a basic lisp tutorial? Or will it confuse matters? Or is it in fact an advantage to dip into Common Lisp at the same time as learning Opusmodus? Thanks Andy

The "Introduction to Opusmodus" tutorial states that the 30 part stages collection of score-scripts and text commentaries..."is available for download as a pdf file formatted as a printable A4 book". But I have not been able to find the download...where can I find it? On a related note, and partly the reason for my wanting to get a pdf, is there any way to make the fonts larger in the Assistant pane? Thanks in advance for any info!

i like to insert many text-attrib (hundreds) into the opmo-function (ADD-TEXT-ATTRIBUTES) ... how can i format it the right way when i generate it by a function? thanx for help!! andré ;;; ordinary... by hand - works fine (add-text-attributes '(nr0 "0") '(nr1 "1") '(nr2 "2") '(nr3 "3") '(nr4 "4") '(nr5 "5")) ;;; generated by a function as a list (if there are many attributes) (setf attr-list (loop for i from 0 to 100 collect (list (compress (list 'nr i)) (write-to-string i)))) ;;; INSERT don't work because of the wrong format.... how can i do that/change the format?? (add-text-attributes attr-list) => E…

For sound synthesis purposes (e.g., for an expressive performance), we may want to use note lengths beyond the restricted set of quantised note durations. However, Opusmodus currently prevents various irregular note duration sequences to be auditioned and throws an error instead. What is really interesting, though, is that the notation for such irregular durations still seem to work. It might make sense the other way round (i.e. refusing to notate certain rhythms -- though I am definitely not voting for introducing that :), but I don't see any real reason why arbitrary rhythms may not be auditioned. As an example, below is a short example of some arbitrary no…

It is handy that Opusmodus can display multiple score snippets and full scores alongside each other. Is there perhaps also a way to re-play some snippet still shown? Either with some GUI element that I may have missed or programmatically (they all have a unique name shown, like "UNTITLED 101 (Snippet)").? There is a function audition-musicxml-last-score, is there perhaps a function to again audition a score that is specified by its name? Thanks! Best, Torsten

Hello, I have a problem, I can not finalize an import of a midi file in OPMO. As you can see in the screenshot, the file is imported into the piano-roll, it is correctly read but when in the File menu I want to access "Midi to Partition", this function remains inactive. Do you have an idea to solve this problem? Thank you in advance. Didier

I'm hoping someone on the forum can help me with this. Since the last update, on my laptop I am unable to use any of my spectral libraries I've created. The tbn-cs one that comes in the app still works, just the ones that I created are not found. I try recreating them and they seem to recreate fine, but after I restart Opusmodus, they still cannot be found. When I check my spectral-data/data and spectral-data/partials, I do see all the necessary files I have created. I think that is happening on my desktop machine, but I can't get to it right now to be sure (I think it was on the desktop that I first found my libraries not being found). However, on both machines, when I f…

is there a possibility to filter some "combinations"? when i have a seq like that: (a4 gs4 a4 gs4 a4 fs4 gs4 g5 bb5 g5 gs4) i want to filter all immediate repetitions with pattern-length = 2 the result would be: (a4 gs4 a4 fs4 gs4 g5 bb5 g5 gs4) because a4-gs4 is the pair that repeats

I like how the function tonality-map allows specifying some input harmony (called tonality) and raw music, where the "raw" music is then quasi-quantised into the given harmony. However, I would like to control in which octaves specific tones are allowed to occur. tonality-map allows specifying an underlying harmony that ranges over multiple octaves, but it seems that internally only octave-less pitch classes are used, and any tone in the harmony can occur in any octave in the result. By contrast, in the spectral tradition of music thinking, you change the underlying spectrum if you scramble in which octaves pitches occur. For example, if you have a spectrum o…

It would be useful for playback, if certain articulations would affect the sounding note durations and velocity values. With some articulations this already seems to be the case (e.g., stacc seems to reduce note durations by 50%), while other articulations are ignored during playback in that regard (e.g., leg is notated, but makes seemingly no difference in playback -- notes played legato are not overlapping, as would be expected, nor are non-legato notes very slightly separated). Other articulations are seemingly even wrongly set (e.g., marc is an accent, but it instead shortens the note). Here is a little example demonstrating the problem, which results in t…

How is it possible to change the MIDI output channel of an instrument? For example, when writing for organ, you have two staffs for the right and left hand, but hands can change manuals, and this is best represented by different MIDI channels. Is there a way to define articulations that result in changing the MIDI channel? Thanks! Best, Torsten

Hi, how can I convert binaries to intervals? (gen-binary-euclidean 1 14 8 8) => (1 0 1 1 0 1 0 1 0 1 1 0 1 0) Each set of (1 0) shoud be replaced by 2 resulting in '(2 1 2 2 2 1 2 2). Thanks for help. Achim

Does Opusmodus perhaps already have some quantisation function that expects a list of floats and that basically rounds these floats into a metric rhythm, including using tuplets? I am aware of vector-to-length – that implements a simple form of what I am looking for, but it does not support tuplets. Other algorithmic composition systems have more sophisticated quantisation facilities. For example, OpenMusic provides the box omquantify (among other functions in the Kant library). http://support.ircam.fr/docs/om/om6-manual/co/Quantification.html I am aware that quantification is a complex process, but perhaps that is already there in …

Hello, I'm a little confused about how to include the :map step tonality form in this example. I start with my tonality-series: (setf g-tonality (tonality-series '( (0 3 5 7 10)) :root '(8 11 4 7 0 4 11 4 7 0 3 8 0 7 0 4 11 4 8 3 8 0 7 …

Hello, I'm trying to import Goldberg Variation No 26 into omn (to then process further), and I'm getting a bunch of fairly crazy rhythms (it certainly is a complicated midi file with ornaments, etc). I've tried both with the midi file included in the distro, and also with the attached. Essentially, I'd love to be able to see pretty much the same rhythms that I see when looking at these midi files in, say, Sibelius, once I export from omn. Anyone able to import that file successfully with respect to rhythmic notation (also, am I correct that there's no way to import musicxml into omn currently), and/or have any tips to offer? thanks very much, micha…

One of my approaches to creating, for example, 'percussive textures'...is to combine different/simultaneous bpms. One way...rendering separate audio files at bpm's say at 53 bpm, 59 bpm, 61 bpm, 67 bpm, 71 bpm...then mixing those individual audio stems together. Or another approach, with a sequencer environment like 'Numerology Pro'...creating individual 'sequencer stacks', each having their own separate sequencer clock set to different bpm, to create realtime MIDI/audio version of example above (or other prime number combinations like 'Prime Pillars' and prime spirals). Note, this is different from basic polyrhythms, which are still within the fr…

Hello, newbie question: I'd like to take an omn list and simply repeat each measure 3 times. If I start with the following code: (setf r-transitions1 '((e (e 1)(-e 3)) (-e (e 3)(-e 1)))) (setf marked (gen-markov-from-transitions r-transitions1 :size 120)) ;;conform to timesignature in omn format (setf r1 (length-span (gen-repeat 20 '8/8) marked :omn t)) ;;define the time signatures (setf timesigs (get-time-signature r1)) ;;stream of pitches (setf pitches '(c4 eb4 f4 g4 bb4 c5 eb5)) (setf pitches (chord-interval-add '(12) pitches)) ;;by spanning r1 onto pitches, pitches will repeat as needed (setf pitches (span r1 pitches)) (setf …

I want to translate individual MIDI velocity integers into Opusmodus velocities (i.e. dynamics symbols like p and f). I am aware that I can do this with vector-to-velocity, but I am surprised that this transformation is seemingly so difficult. Below is a function that can do that, but perhaps Opusmodus itself should make this more simple. (defun MIDI-velocity->OMN-velocity (velocity) "Translates individual MIDI velocity integers into Opusmodus velocity symbols. Example: (MIDI-velocity->OMN-velocity 100) => fff" (let ((scaled-velo (/ velocity 127.0))) ; scale into range 0-1 (second (vector-to-velocity 0.0 1.0 `(1.0 ,scaled-velo 0…

Hello All As I continue my fascination with the fractal structures contained in Per Norgard's infinity series, I am wondering whether it might be possible to apply the infinity to particular scales or modes? Say I want to generate an infinity-series based on a pre-existing scales/modes (like in G major) or by any self-defined mode such as (make-scale 'c2 49 :alt '(1 2 1 1)) Any help much appreciated as always. Kind regards Brian

Hi, I am happily exploring the demo of Opusmodus and have come across some specific? issues to my machine set-up (Mac Pro Mid 2009/OSX 10.9.5). 1- I use a program called 'Total Spaces2' to organize separate desktops. This is the first time it's default key commands of Command 1~9 have caused a problem but when I try to use the Opusmodus key commands for 'Snippet' auditioning, etc ('command' + 1~9) it triggers a TotalSpaces2 desktop change instead. As I use TotalSpaces2 99.9% of my day and have long term muscle memory for it's assignments, I need a way to have different key commands for the 'Snippet' auditioning if possible? Is there a Opusmodus preference file…

The functions omn and make-omn are powerful tools to construct and deconstruct scores of multiple parameters. However, beyond the parameter keywords that are well-documented (:length, :pitch, :velocity, and :articulation) it seems there are other keywords that represent important parameters of the score that should not be omitted (e.g., when we are transforming scores, and do not want to loose important characteristics). Here is an example. When the following melodic line is deconstructed, then beyond the well-documented parameter keywords it also shows the parameters :duration and :leg. If the :leg parameter would be omitted in the construction of the (possib…

Not sure where to report this (if at all) but since I am working myself through the basic documentation, just thought I would let you know FWIW about what I think is a typo? (as it won't evaluate as written). Please let me know if there is a more covert way to report these as i don't want to clutter this forum if you prefer direct contact for little things like this ;-) "Working with Binary Rhythmics This piece demonstrates the use of binary lists as an ingenious way to create and modify rhythm: 0 is a rest-length, 1 is a note-length.

Hello All Can anyone help me develop a function which superimposes a rhythm onto a constant list of pitches? For example, how would I go about superimposing a rhythm like (1/2 1/16 7/16 1/8 3/8 3/16 5/16 1/4 1/4 5/16 3/16 3/8) on to list of pitches like (infinity-series 100 '(g4 gs4)) => (g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 fs4 a4 g4 gs4 a4 fs4 e4 b4 g4 gs4 fs4 a4 gs4 g4 f4 bb4 a4 fs4 e4 b4 fs4 a4 g4 gs4 e4 b4 a4 fs4 b4 e4 d4 cs5 gs4 g4 f4 bb4 g4 gs4 fs4 a4 f4 bb4 gs4 g4 bb4 f4 eb4 c5 g4 gs4 fs4 a4 gs4 g4 f4 bb4 fs4 a4 g4 gs4 a4 fs4 e4 b4 f4 bb4 gs4 g4) …
