  1. Dear Friends, This is the example in the docs for the distribute-stream function. (setf sym '(c4 cs4 d4 eb4 e4 f4 fs4 g4 gs4 a4 bb4 c5 cs5 d5 eb5 e5)) (setf v1 '(1/8 1/8 -1/8 2/8 -1/8 5/8)) (setf v2 '(1/8 1/8 1/8 -1/8 2/8 1/8)) (setf va '(-2/8 1/8 1/8 -5/8 1/8)) (setf vc '(-1/8 3/8 3/8 1/8 1/8)) (setf inst (distribute-stream sym (list v1 v2 va vc))) (setf in1 (make-omn :length v1 :pitch (1~ inst))) (setf in2 (make-omn :length v2 :pitch (2~ inst))) (setf in3 (make-omn :length va :pitch (3~ inst))) (setf in4 (make-omn :length vc :pitch (4~ inst))) (list in1 in2 in3 in4) The result shows that the chromatic pitch sequence is distributed in the voices almost like in every beat, like a 1/4 span. An interesting feature would be the option to specify a series of different length time spans to spread the notes, making the spreading of chords, voicings or serial structures (like hexachords) more controllable. Is it possible , with a keyword ? Another possibility (maybe even better) is to spread the notes according to length sublists of each voice, Best, Julio
  2. Is there any support for swing 8ths in Opusmodus playback ? Best ! Julio
  3. Yes, Janusz I just did it as a fast example to get the idea. Adding a rest is easy. The function would be useful especially when making the rhythms displace to a earlier point (with negative values, like -1/8 or -1/16) where the append would not work.. Would be interesting to keep the bar structure but in this case the function would necessarily involve rotation and not only displacing, in order to put the beginning note/rest to the end of the list or the final note/rest into the beginning of the list. If the bar size is disregarded just using append for forward displacing is enough, but how to make backward displacing ? Best, Julio
  4. Dear Janusz, Thank you, but I did not find such a function. The gen-rotate is a different thing. And the other functions named rotations are more prone to serial manipulations. This length-displace would be more like a displace in time, rewriting the rhythm with an offset (positive or negative) based in a length, like 1/8 or -1/8, or 1/16 or -1/16. Similar to pcs-rhythm but not confined in a 12 module. Best, Julio For example: (setf omn '(q c4 p ten e d4 mp trem s e4 f stacc)) (gen-rotate 1 omn) (s e4 f stacc q c4 p ten e d4 mp trem) but (length-displace 1/8 omn) would be something like (-e q c4 p ten e d4 mp trem s e4 f stacc) Best ! Julio
  5. Dear Friends, I´m searching for a function to make rhythmic displacement of lists and sublists at once. It´s not like rotating, it´s more like displacing all the rhythms by a fixed amount, like transforming this: (-e he. d4 mf e cs4 hs eb4) into this (he. d4 mf e cs4 hs eb4 -e) This means displace all the phrase one 8th note earlier in time. Thank you all ! Best ! Julio
  6. Thanks a lot, Janusz This is a good solution to the note values. But I also have to redistribute the dynamics, like p < f > p, alongside the notes. Maybe a distribute stream of the velocity only ? It looks good, but I got an error here > Error: Too many arguments in call to #<Compiled-function omn-to-time-signature #x30000136862F>: > 4 arguments provided, at most 2 accepted. > While executing: omn-to-time-signature, in process Listener-1(7). > Type cmd-. to abort, cmd-\ for a list of available restarts. > Type :? for other options. 10 > It´s already implemented ? Or this is for the next release ? Best, Julio
  7. Dear Janusz and Friends, ;; I have a question about dictum and its relation with making revisions, like trying to improve the scores for better readability for real musicians. I will demonstrate with a kind of notation I use a lot in my writing. Let´s start with a motif spread through some bars. (setf time-signatures '((2 4 1) (2 4 1) (4 4 1) (2 4 1))) (omn-to-time-signature (gen-repeat 5 '(-e cs6 stacc h. c6 p<f>p long -q)) time-signatures) ;; I use the notation below (the omn result from the expression above) just to keep track of what I´m doing but... ((-e cs6 mf stacc q c6 p<f>p tie+long) (h c6) (-q -e cs6 mf stacc h c6 p<f>p tie+long) (q c6 -) (-e cs6 mf stacc q c6 p<f>p tie+long) (h c6) (-q -e cs6 mf stacc) (h c6 p<f>p tie+long) (q c6 -) (-e cs6 mf stacc q c6 p<f>p tie+long) (h c6) (-q)) ;; for the final writing, I have to rewrite it again in this way, in order to be correctly read and played ((-e cs6 mf stacc q c6 p< tie+long) (q f> tie q p) (-q -e cs6 mf stacc q c6 p< tie+long q f> tie) (q c6 p -) (-e cs6 mf stacc q c6 p< tie+long) (q c6 f> tie q p) (-q -e cs6 mf stacc) (q c6 p< tie q f> tie+long) (q c6 p -) (-e cs6 mf stacc q c6 p< tie+long) (q c6 f> tie q p) (-q)) ;; But, since there are many different ways to express the same length situation, it´s difficult to find a condition to put in the dictum expression to make the substitutions. Doing manually is painful both in Opusmodus or in the notation software. It´s a kind of boring stuff that we have to do as composers. (omn :length '((-e cs6 mf stacc q c6 p<f>p tie+long) (h c6) (-q -e cs6 mf stacc h c6 p<f>p tie+long) (q c6 -) (-e cs6 mf stacc q c6 p<f>p tie+long) (h c6) (-q -e cs6 mf stacc) (h c6 p<f>p tie+long) (q c6 -) (-e cs6 mf stacc q c6 p<f>p tie+long) (h c6) (-q))) ((-1/8 1/8 1/4) (1/2) (-1/4 -1/8 1/8 1/2) (1/4 -1/4) (-1/8 1/8 1/4) (1/2) (-1/4 -1/8 1/8) (1/2) (1/4 -1/4) (-1/8 1/8 1/4) (1/2) (-1/4)) ;;when extracting the length information from the omn phrase, the tie is not present as length. And in this case, maybe a good idea would be to have a kind of "tie2" attribute, only for the cases where the tie is functioning as a duration, and not as an expressive or articulation tie. I think the the tie as a duration should be translated in length value, because essentially this is the meaning of the tie when connecting the same two notes. ;; As the number of notes is altered when using the tie, the distribute-stream processes are also altered. We have to make the manual adjustments and also calculate the new streams of notes considering the repetitions of notes that must occur in the case of durational ties. ;; So, that is my questions concerning the power of Dictum to make revision that could be useful to prepare a score for a definitive and readable form. Looking forward to your ideas and suggestions. All the best ! Julio
  8. Bravo !! Great ! I will have a dedicated computer just to test Opusmodus in Windows !
  9. Dear Janusz, This will be in the next update ? Best, Julio
  10. This is great for motivic development and variation. Best !
  11. Interesting... Maybe Janusz will chime up with some solution. Worked for me at that particular occasion. Best !
  12. Thanks for the observation, Ole ! Best ! Julio
  13. Thanks, Stephane ! Ole, I think that the right way to code my previous example is like this: ((q b4 p leg fs5 < leg e3 < leg a5 <) (e e5 < stacc b5 < stacc c4 mf stacc) (q g5 mf leg a4 leg eb3 leg d4) (e c6 ff stacc b5 stacc a4 stacc) (e c5 > stacc eb5 > stacc gs4 > stacc) (q b4 mf leg f5 leg f5 leg fs5 leg gs5 leg a5) (e cs4 pp g4 < c6 <) (e gs5 fff fermata)) If I put the pp and the < crescendo side by side, we get two C# s. The right way is to put the crescendo for "being carried" by the next g4 note. Looks like each note can carry only one velocity attribute at a time. Best, Julio
  14. I´m studying the Dictum function. For example, this: (setf omn4 '((e b4 fs5 e3 a5) (e e5 b5 c4) (e g5 a4 eb3 d4) (e c6 b5 a4) (e c5 eb5 gs4) (e b4 f5 f5 fs5 gs5 a5) (e cs4 g4 c6) (e gs5))) (dictum '((:butlast leg :bar (1 3 6)) (:apply stacc :bar (2 4 5)) (:any e :apply q :bar (1 3 6)) (:first p :bar 1) (:apply < :bar 1 :event 2) (:apply ff :bar 4) (:apply > :bar 5) (:apply < :bar 7..8) (:apply fff :bar 8) (:last fermata :bar 8)) omn4) ;give me this as result ((q b4 p leg fs5 < leg e3 mf leg a5) (e e5 mf stacc b5 stacc c4 stacc) (q g5 mf leg a4 leg eb3 leg d4) (e c6 ff stacc b5 stacc a4 stacc) (e c5 > stacc eb5 > stacc gs4 > stacc) (q b4 mf leg f5 leg f5 leg fs5 leg gs5 leg a5) (e cs4 < g4 < c6 <) (e gs5 fff fermata)) How to get this result ? ((q b4 p leg fs5 < leg e3 < leg a5 <) (e e5 < stacc b5 < stacc c4 mf stacc) (q g5 mf leg a4 leg eb3 leg d4) (e c6 ff stacc b5 stacc a4 stacc) (e c5 > stacc eb5 > stacc gs4 > stacc) (q b4 mf leg f5 leg f5 leg fs5 leg gs5 leg a5) (e cs4 pp < g4 < c6 <) (e gs5 fff fermata)) Very nice function! Thanks ! Julio
  15. Thanks a lot ! I also used the array in another application. Nice way to use it in the 12-tone matrix. Best ! Julio
  16. FOUND IT !!! (get-form-set '(0 4 9 10 5 3 8 7 1 2 11 6) 'r7)
  17. For example: How to combine from the matrix P0 - second hexachord (F# E G F A G#) with RI5 - first hexachord (D# D F# E G F) Or any hexachordal combination from the matrix (even if it does not form an agregate...) Best, Julio
  18. Dear friends, There is a function to make the 12-tone matrix (twelve-tone-matrix '(3 11 10 2 1 0 6 4 7 5 9 8)) I 0 8 7 11 10 9 3 1 4 2 6 5 0 3 11 10 2 1 0 6 4 7 5 9 8 4 7 3 2 6 5 4 10 8 11 9 1 0 5 8 4 3 7 6 5 11 9 0 10 2 1 1 4 0 11 3 2 1 7 5 8 6 10 9 2 5 1 0 4 3 2 8 6 9 7 11 10 P 3 6 2 1 5 4 3 9 7 10 8 0 11 R 9 0 8 7 11 10 9 3 1 4 2 6 5 11 2 10 9 1 0 11 5 3 6 4 8 7 8 11 7 6 10 9 8 2 0 3 1 5 4 10 1 9 8 0 11 10 4 2 5 3 7 6 6 9 5 4 8 7 6 0 10 1 11 3 2 7 10 6 5 9 8 7 1 11 2 0 4 3 RI The function returns the 48 form matrix of the original 12-tone row. Questions: 1) How can I get some excerpts from the Matrix ? 2) For example, if I want to make a combinatoriality between two hexachords of the matrix, like, for example, the first hexachord of P-0 (3 11 10 2 1 0) + the second hexachord of RI-8 (3 2 6 4 7 5) how can I retrieve the values from the matrix ? Is there some keyword ? Whth this retrieving possibility, the matrix can be very useful for composition. Best ! Julio
  19. Thanks a lot, MIlton ! I´m very happy to see your comment ! Actually, a lot of interesting rhythmic timelines are beyond the 12 units. In indian music there are very long cyclic rhythms and in popular music, the 16 n is very widespread, including the popular drum machines step sequencers. But for the purpose of having a complete set of combinations, any number beyond 12 is too big, generating too much material to make a typology. Maybe in a larger cardinality we can talk about tendencies and not an specific typology. Opusmodus can deal with it, also. Janusz programed a special function based in my dissertation, called pcs-rhythm. It´s well exemplified in the documentation. Here is the forum thread that give birth to the function. All the best and thanks for your kind words ! Julio
  20. Lovely idea ! Eduardo Reck Miranda was born in my city, Porto Alegre / Brasil ! Best ! https://www.exxoshost.co.uk/atari/mirror/myatari/issues/jul2002/camus.htm
  21. Thanks, Stephane I was working around with something like this: (setf mat1 (gen-repeat 2 '((s b4 mf gs3 cs4 fs4) (s a4 mf g3 c4 d4) (s bb4 mf f3 c4 eb4) (s f4 mf d3 g3 c4) (s eb4 mf bb2 gs3 cs4) (s d4 mf a2 e3 g3) (s b3 mf a2 e3 fs3) (s g3 mf c3 d4 a4)))) (setf v1 (gen-trim 3 (omn-to-time-signature (pitch-transpose 12 (list mat1)) '(3 4))) Best !! I´ll try length-span
  22. Dear All, Is there a function to align generated materials to fit in a same space, for example aligning / spanning / trimming 3 voices to fit in a space of, 4 3/4 measures. I know that there are some/many functions related to it, but there are some specific trim-to-time-signature function ? Best, Julio
