  1. Thank you so much for sharing this information! - Rangarajan
  2. Hi, Opusmodus team has done a great job in supporting L-system. I have been spending some time to understand this feature; seems quite powerful. I have just uploaded a blog post on this topic. Your comments and suggestions will be very much appreciated. Does OM implementation support the full functionality as outlined in this paper? - Rangarajan
  3. I have created a 24-bar piece in Opusmodus. I use 10 instruments including Kalimba, Ghatam, Nadhaswaram, Mridangam, and Udukkai. Played through Reaper. The instruments are from UVI and Propellerhead Reason. - Rangarajan
  4. Thanks. Wouldn't it be nice to add it to the official documentation?
  5. Just downloaded and installed the latest version 2.1.26172. Documentation for the function "pprint-score" seems to be missing. - Rangarajan
  6. It seems to me that Stephane's solution is the preferred one if the euclidean-rhythm is to be generated with different seeds. - Rangarajan
  7. This is a great initiative! Thanks to Janusz & team. Will the proceedings be recorded and made available to us for later viewing (for those who cannot attend live)? Also, I see that some talks on the second day will be in Italian. Will there be a translation for the benefit of those who do not understand Italian? - Rangarajan
  8. Thanks! I fully agree with your view on license fee, etc. I guess it is possible to view OM as a Lisp-based Library for music synthesis, if you exclude the IDE, etc. It is perfectly reasonable for the library vendor to charge developers a "royalty", based on the number of copies of their application sold, in addition to the one-time license fee for purchasing the library. - Rangarajan
  9. Thanks a lot! "chord-interval-add" comes closest to what I want. Stephane's suggestion would be ideal if we want all chords to be the same size. If we need chords of different sizes, "chord-interval-add" seems better suited. Coming to a related point, I would love to take advantage of the huge collection of predefined chords in the OM library. For instance, something like the following might be useful (hope I don't sound silly): (harmonic-progression '(maj7 add9 11 7s/9/b5) '(c4 major)) This allows me to get different chord types in harmonic progression on a given scale. - Rangarajan
  10. That is correct, but how to handle the special extended chords (like V7 as I mentioned earlier)?
  11. There doesn't seem to be a direct way to do this in Ableton. However, it seems straightforward to take care of it in Falcon. In any case, would it not be better to support this in Opusmodus? Perhaps we can set a global variable for this?
  12. Sorry if I wasn't clear. Maybe this will be clearer: I would like to generate a chord progression in C Major scale like this: I-vi-ii-V7-ii. Here the V chord is played as dominant 7th. How do I do this? Next, I want to use the different elements of the chord library in OM to generate a chord progression. How do I do that? Thanks, Rangarajan
  13. Hi, I noticed something strange a short while go and need your urgent help. I am sending the score from OM to Ableton Live, and noticed that when I send the key sequence <C2, C3, C2, C3...> via Port 0, Channel 1 to Ableton Live, it is received as <C1, C2, C1, C2, ...> within Ableton. I tried again with UVI Falcon (instead of Ableton) and it was the same behaviour! Why is this happening? Any fixes? - Rangarajan
  14. Opusmodus has a rich set of predefined chords. But I am a bit confused about how to use this. For example, how do I get the "major" triad with "d4" as the tonic in C Major scale? I tried this: (expand-chord '(d4 maj)) but I get "(d4fs4a4)" instead of "(d4f4a4)" - Rangarajan
  15. Thanks a lot Torsten. The *do-verbose* trick works for me. - Rangarajan
  16. When I execute some code in the editor, trace messages appear in the Listener pane. Is there any way to disable the printing of these messages? When I run a large piece of code, it seems to me that these debug messages introduce some delay before the actual code is executed. Of course, these are very useful for debugging, but, it would be nice to have an option to turn these off when not required. - Rangarajan
  17. I am implementing a library of algorithms for music generation using Opusmodus. Here are 3 snippets generated using this library. The midi outputs are sent to Reaper DAW, which in turn uses instruments available in Propellerhead Reason 11 (through VST3i Reason Rack Plugin). - Rangarajan rnd-nil3-4_4.mp3 rnd-nil2-4_4.mp3 rnd5654328-4_4.mp3
  18. Super! I would have saved some time if you had posted this in response to my earlier query! - Rangarajan
  19. Thanks to suggestion by Janusz, I have been able to solve my requirement thus: ;; Returns a list of pitches from the given list, satisfying the supplied noise ;; pitch-list => arbitrary list of pitches ;; noise => Any noise (defun noise-to-pitch-map (pitch-list noise) (mapcar #'(lambda (n) (nth n pitch-list)) (vector-round 0 (1- (length pitch-list)) noise))) Examples: (noise-to-pitch-map '(c4 d4 e4 f4) (gen-white-noise 10 :seed 89)) => (c4 f4 e4 c4 d4 e4 f4 c4 f4 e4) (noise-to-pitch-map '(c4 d4 e4 c5 d5) (gen-gaussian-noise 10 :seed 89)) => (d5 d4 c4 e4 d4 e4 c4 d4 e4 d5) (noise-to-pitch-map (expand-tonality '(c4 major)) (gen-pink-noise 10 :seed 89)) => (c4 d4 d4 e4 e4 f4 g4 a4 b4 b4) - Rangarajan
  20. Thanks Janusz. Let me experiment with it. - Rangarajan
  21. Hi, vector-to-pitch is a very useful function. I want something quite similar with but with a small change. What it does now (from the doc): (vector-to-pitch '(g3 g4) (gen-white-noise 10 :seed 89))(vector-to-pitch '(g3 g4) (gen-white-noise 10 :seed 89)) => (ab3 g4 eb4 a3 b3 eb4 g4 g3 gb4 e4) Instead of giving (low high) as the first argument, I would like to give, for example, a specific scale. Let us say that I want vector-to-pitch to convert the generated white noise to pitches in Major Scale, with tonic of C4. Is this possible? - Rangarajan
  22. Hi, Under the "File" menu, we have "Open Recent" option. This shows the recently opened workspaces as well as files. I feel it will be better to split this functionality into 2 options: "Open Recent Files" and "Open Recent Workspaces". The former is for opening files and the latter is for workspaces. In my working, I use one or two workspaces and each contains many files. And I constantly shift between files. When I close the application and come back, most of the times I only see the files in the "Recent" list, but not the workspaces I opened. This is somewhat inconvenient. This problem could be solved if we have two separate menu options as I mentioned earlier. - Rangarajan
  23. That is a useful addition to the OM environment, but how does that facilitate creating a stand-alone executable? - Rangarajan
