  1. > 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? I cannot offer ready-made examples, but a constraint-based library with various counterpoint (and also harmony) rules ready-made. Cluster engine implements the constraint solver, and many functions for applying user-defined rules to various score contexts in a flexible way (e.g., consecutive notes in certain voices, simultaneous notes across voices at certain metric positions etc). https://github.com/tanders/cluster-engine Cluster rules provides a collection of ready-made rules for the cluster engine library. https://github.com/tanders/cluster-rules Both libraries were initially developed for PWGL, but we ported them to plain Common Lisp to make them usable, e.g., in Opusmodus (where I already used both) and the Max<->Lisp interface I just mentioned in other message. There are some demo/test examples that come with the library (https://github.com/tanders/cluster-rules/blob/master/tests/first-tests.lisp). More extensive documentation (tutorials) are available with the original PWGL versions of the libraries. Some code to smoothly interface the Cluster Library with Opusmodus is part of my tot library (e.g. in the file https://github.com/tanders/tot/blob/master/sources/constraints.lisp). For example, there are means to transform Cluster Library scores into Opusmodus scores (actually, my variant of it, see the docs) and some more complex functions that could be seen as example use cases. For example, the function revise-score-harmonically, expects an existing score that you might create with whatever Opusmodus methods, and some underlying harmony definitions, and that re-harmonises the score accordingly, taking some counterpoint rules etc. into account. I hope the available doc of these packages helps (of which there is also some HTML version online). I cannot provide any more help at this stage, as I am currently extremely busy in my new job... Best, Torsten
  2. Here are some links to another project working on a bridge between Max and Common Lisp. They are calling SBCL in the background using the shell interface of Max, if I recall correctly. The project is not yet very mature, but they have several OpenMusic/PWGL libraries running with a Max interface for pedagogic purposes. https://quod.lib.umich.edu/i/icmc/bbp2372.2017.012/--lisp-in-max-exploratory-computer-aided-composition-in-real?view=image http://www.bachproject.net/2016/10/15/mozlib/ It is tricky to get recent sources of this work online. If you are interested, I suggest you best contact the developers directly, e.g., Julien Vincenot (http://julienvincenot.com/?page_id=269). Say hello from me Best, Torsten
  3. > Sometimes is interesting for hearing snippets with different sounds without having to compile the entire score My Opmo score data structure already allows for that, though you always have to render snippets with an explicit function call, as we cannot define custom shortcuts so far. It is part of my tools at https://github.com/tanders/tot. Check out the function preview-score (https://tanders.github.io/tot/sources/score.html#_g232191). Various other functions allow to transform polyphonic score snippets for one or more instruments in various ways. Best, Torsten
  4. FYI, the changes I proposed are meanwhile merged into the repository at https://github.com/ormf/cm, so you can directly load the Common Music version shared there into Opusmodus 1.3 again. Best, Torsten
  5. I should add that all I fixed was that the full Common Music can be loaded again into Opusmodus 1.3. However, Common Music does not "see" CLM and the interface to it is broken, because CLM is now seemingly defined in another package. However, if anyone wants to use CM with CLM you can load it into a Lisp image without Opusmodus. Best, Torsten
  6. Common Music (CM) is another interesting composition system (http://commonmusic.sourceforge.net), and a recent revision of the old CM version 2 (https://github.com/ormf/cm), which was still implemented in Common Lisp (in contrast to later versions defined in Scheme) can be loaded into and used alongside Opusmodus 1.2 without problems. This was possible primarily due to a largely revised load mechanism of the old CM sources. With the new Opusmodus 1.3 this is not possible any more. It seems the problem is caused by the fact that :CLM (and a number of variants) are still added to *features*, but there is no CLM package anymore. I cannot see the Opusmodus sources, but I assume that all CLM definitions have been added directly to the Opusmodus package. Anyway, due to the present feature CM assumes that CLM is there, but then cannot find its package. Anyway, I found a way around (by changing the relevant feature expressions from #-clm into #-(and clm (not opusmodus)) and will try to have that included in the relevant CM sources at https://github.com/ormf/cm Best, Torsten
  7. EDIT: I fixed the problem by updating the Lisp side of SLIME manually, as the SLIME version in Quicklisp is quite old (20150709). Best, Torsten
  8. Opusmodus 1.2 can be used from within the Emacs editor as well (see the post at the link below for details). For me as a programmer having additionally access to the Emacs Lisp IDE SLIME is greatly preferable due to various advanced features provided by Slime when compared with the more easy-to-use native IDE of Opusmodus. For more information on SLIME see its website: https://common-lisp.net/project/slime Unfortunately, the SLIME link is seemingly broken in Opusmodus 1.3, which I just started for the first time. For those who have no SLIME installed (but have Quicklisp set up), SLIME can be installed with the following command. (ql:quickload "quicklisp-slime-helper") Unfortunately, this results now in an error. To load "quicklisp-slime-helper": Load 1 ASDF system: quicklisp-slime-helper ; Loading "quicklisp-slime-helper" .. > Error: Undefined function asdf/interface::operation-forced called with arguments (#<load-op>) . > While executing: #<standard-method asdf/action:perform (asdf/lisp-action:load-op swank-loader::swank-loader-file)>, in process Listener-2(9). > Type cmd-/ to continue, cmd-. to abort, cmd-\ for a list of available restarts. > If continued: Retry applying asdf/interface::operation-forced to (#<load-op>). > Type :? for other options. I already had SLIME installed, but simply running it does not work either and results in the same error. (cl-user::start-swank) ?

Any help? Thanks a lot! Best, Torsten
  9. Do you perhaps mean the following? Reina, R. (2016) Applying Karnatic Rhythmical Techniques to Western Music. Routledge. https://books.google.co.uk/books?id=4RSrCwAAQBAJ&amp;printsec=frontcover#v=onepage&amp;q&amp;f=false Online material http://www.rafaelreina.org/book-online-material.html Related course http://www.contemporary-music-through-non-western-techniques.com Apologies for my late response. Best, Torsten
  10. There is currently no support for multiple monitors, unfortunately, but it may be on the TODO list of the developers. See also the following link.
  11. BTW: It seems that Opusmodus sends various redundant MIDI events when looking at its realtime output with MIDI monitor. Initially, CC 123 and 120 are initialised to 0 for all 16 channels, but this is done several times (at the end this is done again, but only once). More worryingly, notes are send multiple times. For example, when you send the example below in a score, a note-on for the first note (C5) is send twice almost simultaneously, followed by a note-off for both those notes simultaneously. Indeed, you can commonly hear the result of that as a quasi hick-up in the output, or that the first note is simply skipped. The next notes are also always output twice, but those double events are exactly simultaneously. ((q c5 d5 e5 f5) A related problem is that note-offs and succeeding note-ons are exactly at the same time, which can result in problems for note repetitions. Best, Torsten
  12. I am still working on getting playback for GrandOrgue working properly. I defined a sound set with various articulations (shown in a related post, see link below) for setting, e.g., which manual to use for the current hand, and which stop combinations on that manual. Those articulations already work individually in Opusmodus. The problem I am facing is that I need to constantly combine multiple of such articulations in a single note. For example, I may need to specify that the right hand stops playing on the manual I (one articulation), that it instead plays on manual II and III coupled (two further articulations) and which stop combinations to use for those manuals (two more articulations). So, in this example we have five articulations on a single note, and each needs to send a specific MIDI event. Such an occurrence is something completely normal in organ literature. In OMN, this could be written, e.g., as follows using my sound set shown in the post linked below. '((q c4 -I+II5+III6+II+III)) Now, my only problem is that whenever there are two articulations combined for a single note, where each should output its own MIDI event, Opusmodus always only outputs just one of these MIDI events. I confirmed this by checking the resulting MIDI events both in an exported MIDI file and with a realtime MIDI monitor (https://www.snoize.com/MIDIMonitor/). Note that my setup works with other software (notation software and DAWs), as they allow for having multiple articulations allocated to a single note outputting separate MIDI events. Is this perhaps somehow possible with Opusmodus as well? Best, Torsten PS: I realise that Opusmodus does send multiple MIDI events if multiple MIDI events are explicitly specified for a single articulation, as in the "VSL Cello Solo" file. However, I cannot really explicitly define all the possible articulation combinations as individual articulations instead, as what would result in an impractical large number of them. There are currently individual 48 articulations (for an organ with three manuals and 10 preset combinations each), and these articulations can be combined in various ways in pairs, triplets, quadruples etc., which would result in an impractically huge number of articulations to define. PPS: One potential workaround for some situations would be to instead allocate some of these articulations to rests immediately preceding the notes for which they are needed, but that is not possible either, because custom articulations cannot be added to rests. Instead, additional notes are added. PPPS: For completeness: a related post.
  13. In common music notation, if you use some "sticky" playing technique and you want to "disable" it later, then you should tell so the performer, should you not? Best, Torsten
  14. > Check the GET-RUNNING function. This will explain as well how to use floats in tuning. Is that a new function? It is not available in my image. Best, Torsten -------------------------- Unfortunately, evaluating add-cents-tuning-to-text-atrributes results in an error for me. > Error: ((= (length (explode i)) 5) (filter-first 3 (explode i))  (filter-first 2 (explode i))) can't be destructured against the lambda list (ccl::test true &optional false), because it contains 4 elements, and at most 3 are expected. > While executing: (:internal ccl::nx1-compile-lambda), in process Listener-2(9).
  15. Good to hear that you have both IRCAM solo-instruments and conTimbre. I was considering getting one of those at some stage. What is your impression of either using them for sequencing with a DAW or notation software? Best, Torsten
