  1. how is it currently with the support of microtonality (omn & xml-display)? thanks for some informations andré
  2. if you want to change VELOCITY of a technique... (defun replace-velocity-of-a-technique (omn-list &key technique velocity) (flatten (loop for i in (single-events omn-list) when (equal (car (omn :articulation i)) technique) collect (pattern-map (list (list (list '? technique) (list velocity technique))) i) else collect i))) (replace-velocity-of-a-technique '(e. c4 p tasto d4 ponte e4) :technique 'tasto :velocity 'f)
  3. if you want to augm/dim the LENGTH of a special technique... you could use that... or extend it... (defun modify-length-of-a-technique (omn-list &key technique (factor 1) (modification 'augmentation)) (flatten (loop for i in (single-events omn-list) when (equal (car (omn :articulation i)) technique) collect (cond ((equal modification 'augmentation) (length-augmentation factor i)) ((equal modification 'diminution) (length-diminution factor i))) else collect
  4. a perfect listing, very clear and useful!
  5. ...except that makes you a fun and makes you happy - and that is just as important! added 10 minutes later so the question will be what can be better, which will be more exciting than what deep learning (or traditional algorithms) can produce. very fast then - in my opinion - the production becomes quite simple and well done, but this has nothing to do with art (if you want) - it will be the "imitation of art", also algorithmic tools pushing you in this direction - is it "music" or the simulation of "music"?. but as VON FOERSTER said: "the map is the territory"... counteracting (radic
  6. critical thought about this: I think in the near future this will work through "deep learning". So it is questionable how useful it is to formalize such manual and traditional "activities", such "complex rules systems" in CODE. this question generally arises in areas that focus on imitating and executing existing styles. greetings andré
  7. you are brilliant! will it be part of the "official OM", or should i integrate it in my USER LIBRARY? regards andré
  8. the "STEP-TO"-idea could be used more common... with other parameters...welcome to extend/develop it... for mulidimensional/multiparametrical rnd-walks (first example)? :-) ;;; FUNCTION -> same as step-to-pitch (defun reading-list-by-steps (&key steps values start) (let ((pos (car (position-item start values)))) (append (list (nth pos values)) (loop for i in steps do (setf pos (+ pos i)) when (> pos (length values)) do (setf pos (+ 0 i)) collect (nth pos values))))) ;;; EXAMPLES ;;; rnd-wa
  9. is it also possible to start at a specific pitch? (tonality-step '(c4 d4 e4 g4 a4 f4) '(1 1 -1 2 2 -1) :start 'e4)
  10. extended idea: would be nice to do it with chords => instead of a scale, a sequence with chords... thanx a lot for such a quick developing/implementation!!
  11. here is a little "sketched" function STEP-TO-PITCH , perhaps OM could further develop the function... ;;; FUNCTION (defun step-to-pitch (&key steps pitches start) (let ((pos (car (position-item start pitches)))) (append (list (nth pos pitches)) (loop for i in steps ;; setting pos by add the step to pos do (setf pos (+ pos i)) ;; when pitch-range to small then reset to lowest pitch+step ;; could be a more intelligent solution when (> pos (length pitches)) do (setf pos (+ 0 i)
  12. STEP-TO-PITCH - function ...perhaps OM could implement such a STEP-TO-PITCH function (in a more professional programming way)? ...in that way it's simple to map any/same GESTALT(S) on any/different (pitch-)MEDIAS (like pitchfields/spectral/whatelse). ...would be the shortest way to "project" (certainly in varèse-way) for example ALL MY DUCKS to whole-tone-/minor/messiane-x or on a inclined plane "pseudo-code" for this non-sense-example: -> (setf intervals (pitch-to-interval pitches-all-my-ducks)) -> (step-to-pitch intervals :tonality 'messiaen
  13. this is probably a misunderstanding... intervals in a sense of STEPS, not as second/third/... as steps in a predefined/organized pitch/frequency-space... ;;; like that (defun interval-projection-on-pitchfield (&key pitchfield intervals (base 0)) (let ((integers (pitch-to-integer (interval-to-pitch intervals))) (base-0-integers) (centering) (pos)) (setq base-0-integers (loop for i in integers collect (+ (abs (find-min integers)) i))) (setq centering (if (evenp (find-max base-0-integers)) (/
  14. i'm not sure -> but interval-to-pitch works on "chromatic" only!? and not on other TONALITIES...?
  15. short question... is there a function in OM to map an interval-list directly on a TONALITY or a SIEVE? in a way that the intervals are like steps? ..i coded that alreday for myself, but perhaps there is an OM-solution for such things? nonsense-example: (setf intervallist '(1 1 0 -2)) (setf pitches '(c4 e4 g4 b4)) => :start 'c4 => result: '(c4 e4 g4 g4 c4) thanx andré
  16. my wish for SINGLE-EVENTS would be to add user-defined "informations" to an event -> like voice-number, oder instrument, or....
  17. an other solution... same result... greetings andré ;;; by using SINGLE-EVENTS -> my preferred tool (defun alt-add-3rd-quarter (omn-list) (loop for i in (single-events omn-list) when (equal (first i) 'q) append (omn-replace :pitch (chord-interval-add '(4) (list (second i))) i) else append i)) (alt-add-3rd-quarter '(e c4 p d4 q e4 f stacc e f4 p a4 q g4 f stacc)) => (e c4 p e d4 p q e4gs4 f stacc e f4 p e a4 p q g4b4 f stacc)
  18. greetings andré (pitch-to-interval (expand-tonality '(c5 messiaen-mode4))) ; => (1 1 3 1 1 1 3) (pitch-to-interval (expand-tonality '(c5 messiaen-mode5))) ; => (1 1 3 1 1 1 3) -> should be (1 4 1 1 4 1)
  19. have a look -> missing slur/tie (i don't kno the correct expression) between bar1 and bar2... greetings andré p.s. i will post the troubles/bugs here in "SOURCE CODE", okay? (setf mat1-pitches '(a4 g4 eb4 f4 a4 b4)) (setf mat1-durations '(-7 23 -7 5 11 7 -5 11 17)) (setf mat1-lengths (gen-length mat1-durations 1/20)) (setf omn (make-omn :pitch mat1-pitches :length mat1-lengths :velocity '(p)))
  20. for me also... would be nice "to split screens" (composer, score etc...) to work/see it on different windows/screens regards andré
  21. i see, it was a bad example... but perhaps it will be possible to display grace notes in a tuplets in the future?
