  1. the LOOP-cycles produces data-sequences with lengths about 5 to 20 sec for this... stop and wait via SLEEP is oaky.... inside the loop: i send the datas (the sequences) to screens (generative score + conducting for the musicians / polytempo) and MAXMSP (sound/modsynth) ... this is via OSC for accuracy/coordination so it works fine like that... but: LISP is not exactly suitable for REALTIME processing
  2. dear torsten, that works perfect! so i can display what my algo is doing in each loop... thx
  3. is there a possibilty to ONLY show INSIDE the LISTENER what i like to: some (print ....)-stuff ...and not all the "function-calls" like ..... ratio-to-msec rnd-pick :seed 990096 rnd1 :seed 858709 compress rnd1 :seed 223329 compress list-to-string ratio-to-msec ratio-to-msec ratio-to-msec prob :seed 115209 prob :seed 40751 stop-score-player score-player .... thanx for a hint andré

  8. lieber torsten, herzlichen dank! beste grüsse andré
  9. yes, but i do not compose with OPMO - it's too strange with rhythm/instrumentation/notation. most of the time i'm sketching with OPMO and compose "by hand". guitar-scordatura: i thought i'd rather "pull the pitches out of MIDI/XML" and then convert them.. i will see... but, THANX! greetings andré could look like that (excerpt of a piece for solo trp - also with some SORT-ALGORITHMS inside (sketched/calculated with OPMO) works fine with SIBELIUS for layouting etc...
  10. thanks, dear julio, i'll take a look at it, but depending on the situation, programming takes more time than doing it by hand
  11. i am currently working on a piece for piano, guitar and drums. the guitar will have a "scordatura" so that i can do different harmonics and resonances than with the usual tunings. so that I can now make a more readable score, I would like to write the guitar part on two systems: one system as it sounds and one readable for the guitarist (because of the scordatura/fingerings)... it would be nice if we could do a FUNCTION which transforms the "sounding pitch part" (readable in score) into the "guitar-specific-part" (how to play for guitarist)...
  12. dear julio i would code it! you could do a "systematic/formalized sketch" (not in LISP) and with that you would try to program a function best a.
  13. here it is... but NOT microtonal. just for equal tempered tunings it was too complicated (and not necessary) for me to code it (with attributes and cents, it's a bit ... ), so i coded it just for my needs ... for equal tempered tunings... could use it for guitar/strings, just to have a list of your SCORDATURA-harmonics to work with. would be interesting if someone could CODE a function which transforms a "sounding-pitch-guitar-score" into the "play-score". so i wouldn't have to do it by hand... where are the guitar players here? julio? janusz? greetings andré (defun sort-to-pitch-events (events sort) (let* ((int (loop for i in events collect (list (pitch-to-integer (second i)) i))) (out (sortcar sort int))) (loop for i in out collect (second i)))) ;;----------------------------------------------------------------------------------- (defun gen-natural-harmonics (openstrings &key (scale nil) (n 16)) (progn (add-text-attributes '(str1 "str1") '(str2 "str2") '(str3 "str3") '(str4 "str4")'(str5 "str5") '(str6 "str6")) (let* ((cent-list (cents-to-attribute '(0 2 0 -14 2 -31 0 4 -14 -49 -2 41 -31 -12 0))) (harmonic (loop for i from 2 to n collect (compress (list 'num i)))) (harmonic-seq (loop for i in openstrings for j in (list 'str6 'str5 'str4 'str3 'str2 'str1) collect (make-omn :pitch (rest (harmonics i n)) :length '(q) :articulation (loop for i in cent-list for x in harmonic collect (if (equal i '-) (compress (list x '+ j)) (compress (list i '+ x '+ j)))) :span :pitch)))) (if (null scale) harmonic-seq (sort-to-pitch-events (single-events (flatten harmonic-seq)) '<))))) ;;----------------------------------------------------------------------------------- ;;----------------------------------------------------------------------------------- ;; attributes: string number + partial number + CENTS ;; sorted by strings (gen-natural-harmonics '(e1 a1 ds2 g2 a2 b2) :n 7) => ((q e2 num2+str6 b2 2c+num3+str6 e3 num4+str6 gs3 -14c+num5+str6 b3 2c+num6+str6 d4 -31c+num7+str6) (q a2 num2+str5 e3 2c+num3+str5 a3 num4+str5 cs4 -14c+num5+str5 e4 2c+num6+str5 g4 -31c+num7+str5) (q eb3 num2+str4 bb3 2c+num3+str4 eb4 num4+str4 g4 -14c+num5+str4 bb4 2c+num6+str4 cs5 -31c+num7+str4) (q g3 num2+str3 d4 2c+num3+str3 g4 num4+str3 b4 -14c+num5+str3 d5 2c+num6+str3 f5 -31c+num7+str3) (q a3 num2+str2 e4 2c+num3+str2 a4 num4+str2 cs5 -14c+num5+str2 e5 2c+num6+str2 g5 -31c+num7+str2) (q b3 num2+str1 fs4 2c+num3+str1 b4 num4+str1 eb5 -14c+num5+str1 fs5 2c+num6+str1 a5 -31c+num7+str1)) ;; sorted by pitch (gen-natural-harmonics '(e1 f1 a1 d2) :n 7 :scale t) => ((q e2 mf num2+str6) (q f2 mf num2+str5) (q a2 mf num2+str4) (q b2 mf 2c+num3+str6) (q c3 mf 2c+num3+str5) (q d3 mf num2+str3) (q e3 mf num4+str6) (q e3 mf 2c+num3+str4) (q f3 mf num4+str5) (q gs3 mf -14c+num5+str6) (q a3 mf -14c+num5+str5) (q a3 mf num4+str4) (q a3 mf 2c+num3+str3) (q b3 mf 2c+num6+str6) (q c4 mf 2c+num6+str5) (q cs4 mf -14c+num5+str4) (q d4 mf -31c+num7+str6) (q d4 mf num4+str3) (q eb4 mf -31c+num7+str5) (q e4 mf 2c+num6+str4) (q fs4 mf -14c+num5+str3) (q g4 mf -31c+num7+str4) (q a4 mf 2c+num6+str3) (q c5 mf -31c+num7+str3))
  14. thanx! (i'm doing a little function to get all the natural harmonics for guitar tunings equal tempered or microtonal...)
  15. hi all little question: i would like to SORT an (single-event)-list by pitch... and be able to keep the event-data "in the set" (=> the attribute-cents should be bound to pitch!) ((e e4 mf) (e a4 mf) (e d5 mf) (e g5 mf) (e b5 mf) (e d6 mf) (e b4 mf 2c) (e e5 mf 2c) (e a5 mf 2c) (e d6 mf 2c) (e fs6 mf 2c) (e a6 mf 2c) (e e5 mf) (e a5 mf) (e d6 mf) (e g6 mf) (e b6 mf) (e d7 mf) (e gs5 mf -14c) (e cs6 mf -14c) (e fs6 mf -14c) (e b6 mf -14c) (e eb7 mf -14c) (e fs7 mf -14c) (e b5 mf 2c) (e e6 mf 2c) (e a6 mf 2c) (e d7 mf 2c) (e fs7 mf 2c) (e a7 mf 2c) (e d6 mf -31c) (e g6 mf -31c) (e c7 mf -31c) (e f7 mf -31c) (e a7 mf -31c) (e c8 mf -31c) (e e6 mf) (e a6 mf) (e d7 mf) (e g7 mf) (e b7 mf) (e d8 mf)) any solutions? thanx! andré
  16. real LISP knowledge is very helpful for me. i think it's enough if you know (work with) the fundamentals - like... list/append/cons/loop/loop-inside-a-loop/progn/push/pop/collect/defun... ... so that you can code your specific solutions! greetings andré
  17. i know i'm not a programmer, but it probably makes sense to be able to enter both variants/formats for some functions, but not for others...
  18. you have to put the bar-numbers into a list... i makes sense in my opinion - perhaps you want to "find" more then one bar... (find-bar '(1 2) mat) => ((c4 db4 ab4 f4 g4 bb4) (a4 eb4 b4 e4 d4 gb4))
  19. dear all here's a function (revised, should work correct now) to work with rotations - based on the work of karel goeyvaerts (defun goeyvaerts-rotation* (&key pitches static-pitches generations goeyvaerts-transpose-interval (direction 'up) low-border high-border correction-interval) (let ((pitches (filter-remove (pitch-to-midi static-pitches) (pitch-to-midi pitches)))) (midi-to-pitch (append (list (append pitches (pitch-to-midi static-pitches))) (cond ((equal direction 'up) (loop repeat generations for x in (gen-repeat 50 goeyvaerts-transpose-interval) collect (append (setf pitches (append (loop for i in pitches when (> (+ i x) (pitch-to-midi high-border)) collect (+ x (- i (abs correction-interval))) else collect (+ i x)))) (pitch-to-midi static-pitches)))) ((equal direction 'down) (loop repeat generations for x in (gen-repeat 50 goeyvaerts-transpose-interval) collect (append (setf pitches (append (loop for i in pitches when (< (- i x) (pitch-to-midi low-border)) collect (+ i correction-interval) else collect (- i x)))) (pitch-to-midi static-pitches))))))))) EXAMPLE: ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;; an example with multiple objects inside a chord / GOEYVAERTS uses it woth octave-rotations and with static pitches ;;; here i do it different.... ;;; :goeyvaerts-transpose-interval => in every generation the elements are transposed by next interval (circular) ;;; :static-pitches => will not rotate!! ;;; :high-border => if a pitch is higher then this it will be transposed down by :correction-interval ;;; EVALUATE THIS (setf groups (loop for i in (goeyvaerts-rotation* :pitches '(b3 d4 eb4 gb4 f5 e5 g5 ab5 a4 bb4 db5 c6) :static-pitches nil;'(e4 eb5) :direction 'up :generations 20 :goeyvaerts-transpose-interval '(2 3 5 7 5 3) :low-border 'a2 :high-border 'eb6 :correction-interval -36) collect (gen-divide '(5 3 2 2) i))) ;;; AND THIS / cmd1 => so you see the chords an see the rotation etc..

  20. violà... now it works fine - OPMO could integrate it.... it's easier than i thought: a single index-series is read from the r-i and only this one is used! similar to LACHEMANN, only he determines this index-series himself (for that i coded this simple row-permutation-function)... greetings a. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;; SUB (defun row-permutation (n row rules &key (one-based nil)) (let* ((rules (if (equal one-based t) (mapcar '1- rules) rules))) (loop repeat n collect (setf row (position-filter rules row))))) ;;; MAIN (defun serie-proliferantes (n row) (let ((index-no (loop for x in (pitch-to-midi (pitch-invert (gen-retrograde row))) collect (or (position x (pitch-to-midi row)) (position (- x 12) (pitch-to-midi row)) (position (+ x 12) (pitch-to-midi row)))))) (list row (pitch-invert (gen-retrograde row)) (row-permutation n (pitch-invert (gen-retrograde row)) index-no)))) (serie-proliferantes 6 '(c5 ab4 g4 db5 e4 d4 bb4 eb4 b4 f4 fs4 a4)) => ((c5 ab4 g4 db5 e4 d4 bb4 eb4 b4 f4 fs4 a4) (a4 c5 cs5 g4 eb5 gs4 e5 d5 f4 b4 bb4 fs4) ((fs4 a4 g4 cs5 d5 c5 eb5 gs4 b4 f4 e5 bb4) (bb4 fs4 cs5 g4 gs4 a4 d5 c5 f4 b4 eb5 e5) (e5 bb4 g4 cs5 c5 fs4 gs4 a4 b4 f4 d5 eb5) (eb5 e5 cs5 g4 a4 bb4 c5 fs4 f4 b4 gs4 d5) (d5 eb5 g4 cs5 fs4 e5 a4 bb4 b4 f4 c5 gs4) (gs4 d5 cs5 g4 bb4 eb5 fs4 e5 f4 b4 a4 c5)))
