  1. Hi @Wim Dijkgraaf- I'm using git and just do a standard commit from the folder my workspace an .opmo files are in once I update files. I use OM on two different machines so version control is essential to me not going crazy. Also, my supporting python files (and the music21 library). I think a git integration might be a cool feature and save some time. I doubt it's a high priority though because there are workarounds (like mine). Hope that helps.
  2. This is important stuff and I'm glad we, or rather OpusModus, has the microtonal notation now. I'm taking a class on microtonal music now and having to create a lot of 5-limit and 7-limit lattices. It'd be cool to be able to visualize lattices in the IDE.
  3. I'm unsure as to how to post images inline so I hope this will make sense. Pitch/melody inversion is interesting to me. To try that out, I'm going to take a simple line from Beethoven (pic 1). Using a negative melody, I invert around the tonic to be the following (pic2). The difference in OMN is this: (setf pitches '(a4 g4 fs4 a4 d5 a4 fs5 d5 a5 fs5 e5 d5)) (setf lengths '(e. s e. s e. s e. s e. s e e q)) to this: (setf lengths '(q e q e q e q e q e q e h)) (setf pitches '(f4 g4 gs4 f4 c4 f4 gs3 c4 f3 as3 as3 c4 d4)) If I try the pitch inverse function described above, I start with this: (pitch-invert '(a4 g4 fs4 a4 d5 a4 fs5 d5 a5 fs5 e5 d5)) and I get this: (a4 b4 c5 a4 e4 a4 c4 e4 a3 c4 d4 e4) Which is a bit different probably because I did my manual job incorrectly. However, it's a happy mistake which I will keep because I like it better! Having said that I do think the pitch-inverse is what you're looking for and a very cool compositional tool to have in Opusmodus!

  5. VMWare is a bit more tricky for me being on an AMD rather than Intel (which Mac uses). Latency was severe. My workaround is just to remote in to my old mac and it seems to be working much better.
  6. Curious about the file formats for import. I'm seeing "txt" but I'm wondering if formats that are output by, say Python or R can be used. Just tested and was able to load a .csv but not a .feather or .rds file. Pulling in a dataframe and building a composition off that data will be an interesting experiment.
  7. Thank you for the help everyone! These are great for my section on serialism. I've switched my focus to serialism and neural networks (I found an example that generates content from simple Irish Folk songs in .mid files). My focus is on the ever-changing relationship that composers have with rules and procedures. https://www.mathworks.com/matlabcentral/fileexchange/69632-code-for-webinar-deep-learning-for-signals-and-sound Tom
  8. Hello, I'm making a presentation on 12-tone composition in an educational context. While my focus is on a 12-tone map (including OMN and OpusModus code) I want to begin with some more simple examples e.g. a Canon, a Fugue, first second and third species counterpoint. While I can create a canon, counterpoint and a fugue myself with a bit of time, it would be much less time-consuming for me if I were able to use existing examples. Is there an existing library of OMN examples of these types of compositions? If not, I'm happy to post mine once I'm done. Tom
  9. Thanks, Stephane. This is a great example to work from. I've not created a piece with multiple parts exclusively in Opus Modus yet so this is a good starting point. I received an error with an undefined function. Is that due to a version error or is there a function I need to build and reference as a separate file? Or perhaps its something else. Here's the error I received when I evaluated the file:
  10. Ah, ok. So the script is not a score and must be added to a score? Good to know. That might fix my problem with the evaluate and play. One other thing I am noticing: Opusmodus is crashing whenever the window for another application is brought to the front in OSX. This has only happened since I upgraded to 1.2.21003 two days ago. It did not happen before. Any idea what that cause might be? Thanks, Tom
  11. Hello! I'm using the Version 1.2.21003. After I "evaluate and play" a score in a Workspace, all other score evaluate and play the first score even if I remove the file. For example if I have: Score A Score B and I evaluate and play Score A, when I evaluate and play Score B it plays Score A. If I remove score A, and evaluate and play score B it will play Score A (even though Score A is no longer there). If I remove all scores and evaluate and play in a blank screen, it will play score A. Additionally, after evaluating and playing multiple times, Opus Modus will cease to be able to evaluate and play anything. It gives me the following error: ? compile-score nil > Error: Too few arguments in call to #<Compiled-function serialize-scores #x3000015A629F>: > 0 arguments provided, at least 1 required. > While executing: serialize-scores, in process Listener-1(6). > Type cmd-. to abort, cmd-\ for a list of available restarts. > Type :? for other options. 1 > Once this occurs, it will be the same for all scores. Any idea what's happening? Thanks, T
  12. Hello! I'm very interested in the Euclidean Generator but not sure how to use it. I see a video mentioned by Stephane here: http://composersforum.ning.com/forum/topics/new-video-tutorial-epic-euclidean-percussion-generator-with But I could not find it in the link: http://algorithmicmusiccomposer.blogspot.fr/ Is this video still available? I would love to see it. Thanks! Tom
  13. I'll look into the tonality-map function. Good to know about the score parameters as I will be outputting this as a score as well. Thanks! Tom
