  1. perhaps some (old) hocket-function... ?
  2. for my current project i have to CONVERT/MAP pitches/lengths/velocity or MIDI into a binary sequence. so i coded this simple FUNCTION... feel free to use/adapt.... greetings andré ;; SUB (defun fill-to-x-bit (listseq &key (bitlength 7)) (loop for i in listseq when (< (length i) bitlength) collect (append (gen-repeat (- bitlength (length i)) 0) i) else collect i)) ;; MAIN (defun convert-to-binary (alist &key (parameter 'pitch) (length-resolution 127) (velocity-resolution 12) (pitch-resolution ni
  3. i'm very interested in!! thx to you JULIO!!! strukturnetz is not a piece, it's "a kind of technique" he used you could read about it here: https://www.amazon.de/Differenzen-Poststrukturalistische-Beispiel-Lachenmann-Ferneyhough/dp/3931264157 listen here... the STRUKTURNETZ is also "notated" in the score (on top)
  4. like that? should work... it "loops" x-times (depends on length of seeds-list) and collect the rhythms... (setf seeds (vector-round 1 100 (gen-white-noise 8 :seed 13))) (setf rhythm (loop for i in seeds collect (euclidean-rhythm 16 4 16 's :type 2 :seed i))) perhaps there is an OPMO-solution, this is LISP
  5. would be interesting. it has quite some (distant?) aspects of LACHENMANN's "strukturnetz", and could be nice to work in such an direction...
  6. dear ole i have no "preseted" soundsets for my work... in my current "sketch" i'm using/something something like this.. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (add-text-attributes '(e-bow "e-bow") '(harm-I "harm-1") '(harm-II "harm-II") '(harm-III "harm-III") '(harm-IV "harm-IV") '(harm-V "harm-V") '(harm-VI "harm-VI")) (def-sound-set gm-guitar :programs (:group guitar ord 0 bartok-pizz 1 tap 2 ponte 3 harm-I 4 harm-II
  7. or... (loop for x from 7 downto 1 for y from 1 to 7 collect (list x 3 y))
  8. i have been working with conTimbre for a long time and it is exactly what i was looking for. playing techniques can easily be done by OPMO or SIBELIUS (vst3) via program changes. it has a great many different playing techniques. I always found IRCAM_LIB to be very inadequate, as there were not enough playing techniques etc. / you can also control CT via OSC (and as standalone or via MAXMSP). when I wrote for ensemble with additional e-player, CT-live always worked very well. (The only negative point I could say is that there are a few SAMPLES that weren't played / recorded very wel
  9. Dear all Today I dealt briefly how to control PROCESSING (software and programming language) by Midi. There is a great interface for this: "rwmidi" by Giuseppe Torre. You can download and install it, it works fine! A short Video (no Sound) with a very simple Processing Example movie.mov I think this is a good combination if you want to visualize your midi output (or just use de midi-data in realtime) or if you want to program a separate VISUAL track in OPMO. Here is a small example (I can't program usable in PROCESSING yet, sorry :-)) Downloads
  10. thanks... i will post the CODE and some videos etc. when i have finished the work - premiere will be in november... greetings andré
  11. dear all here's an example (from my current work)... this little video shows how i generate/display SCORE (instrumental parts) on a screen + virtual conductor (piano part). the example is "nonsense", but shows how it looks/works... you see the bars (generating), the cue, beat... and the arrow (that shows you where to read/play) ...also you hear some bad (sry) sound-simulation of the setup. in this way i can generate a whole piece in realtime on STAGE (all musicians will read their part from their own screen). this one will be for 5 instruments, ePlayer and m
  12. here is a sketch for an alternative "binary-(or element-)layer-FUNCTION (defun element-layer (lists &key (rnd nil)) (let ((lists (if (null rnd) lists (rnd-order lists :list t)))) (car (last (loop for x in (rest lists) with list = (car lists) collect (setf list (loop for i in list with cnt = 0 when (equal i 0) collect (nth cnt x) and do (incf cnt) else collect i)))))))
  13. testing videoplayer in OPMO.mov whitenoise.mov
  14. you want to map some integers (in your case pc..) to attributes? like that? (position-filter '(0 1 2 3 4 5) '(pizz arco ponte molto-ponte stacc stacc+pizz ten+arco ten+molto-ponte)) => (pizz arco ponte molto-ponte stacc stacc+pizz) (position-filter (pcs '6-Z10) '(pizz arco ponte molto-ponte stacc stacc+pizz ten+arco ten+molto-ponte)) => (pizz arco molto-ponte stacc stacc+pizz ten+molto-ponte) or in pure CCL (loop for i in '(0 1 2 3 4 5) with attr-list = '(pizz arco ponte molto-ponte stacc stacc+pizz ten+arco ten+molto-ponte) collect (nth i attr-list)) => (piz
  15. i've made different user folders... named: user editing user pattern matching .... ...or you could put all in the same... (i realized for my work, that most of the time i'm using a "coded function" only for a specific project/work. so i stopped it to put all special functions into my user library. now, i have the functions only in my project workspace...)
  16. in german... https://www.amazon.de/Programmieren-COMMON-LISP-Otto-Mayer/dp/3860257102 (but without LOOP) https://www.tutorialspoint.com/lisp/index.htm https://lisptips.com https://www.youtube.com/channel/UCMV8p6Lb-bd6UZtTc_QD4zA
  17. you're welcome!! i think for specific solutions it helps a lot to learn some LISP-basics (loops/conditionals/car/cons/...), then you have the possibility to make your own additional functions/libraries in OPMO. and OPMO is really great for such things!! greetings andré
  18. like that..?... some code... greetings andré (defun replace-velocities-in-a-seq (omn-list &key pitch velocity-list) (flatten (loop with cnt = 0 for i in (single-events omn-list) when (equal (cadr i) pitch) collect (omn-replace :velocity (nth cnt velocity-list) i) and do (incf cnt) else collect i when (> cnt (length velocity-list)) do (setf cnt 0)))) (replace-velocities-in-a-seq '(e c4 ppppp d4 d4 e4 f4 d4 d4 g4 b4 d4 d4 d4 d4) :pitch 'd4 :velocity-list
  19. okay, then it seems to be a AUDULUS- or MOD-SYNTH-"problem". (audulus is only for simulation, real mod-synth for live) thanks!
  20. dear janusz at the moment i'm working with AUDULUS 3 and OPMO, work's fine. but there are some problems with the articulation. is it possible that in ord. there is a little "overlapping" between two notes? in this case AUDULUS don't "recognize" a change of velocity etc... with stacc it works fine (but with a gap). is there a "non-overlapping"-articulation with almost no gap between the notes? thanks andré
  21. (setf scale '(c4 d4 e4 f4 g4 a4)) (setf scale (omn-replace :length 'e scale)) ;; or (make-omn :pitch '(c4 d4 e4 f4 g4 a4) :length '(e q e e s t))
  22. you could use LENGTH-MODIFY "LENGTH-MODIFY will modify a series of lengths by adding, subtracting, multiplying or dividing them with a list of duration values. If the count argument is not given to LENGTH-MODIFY then the count is chosen at random."
  23. really interesting, janusz!! great!!! i will like DENSITY
