i would like to define my own articulations (because in CONTIMBRE  http://www.contimbre.com  you have lot of possibilities with programm-changes... and for mapping i have to define it properly)

 

:::::::::::::::

 

(setq articulations '(arco -  -  pizz - -));; -> that works fine because ord-omn

(setq articulations '(arco -  -  pizz - - legno-battuto - whatever - - - -  );; -> i would like to write such user-defined expressions

-> is there a possibilty?

 

:::::::::::::::

 

(setq vn (make-omn :length lengths
                   :pitch pitches
                   :articulation articulations)) ;; but here is the omn-error with my own expressions, is there any solution?

 

:::::::::::::::

 

if it would work i could map like this:

(def-sound-set gm-violin
   :programs
  (:group violin 
          arco 40
          legno-battuto 50
          pizz 60
          whatever 70))

 

(def-score example
           (:key-signature 'chromatic
                           :time-signature '(4 4)
                           :tempo '(q 70)
                           :layout (violin-layout 'violin))

  (violin :omn vn
          :channel 1
          :sound 'gm-violin))

 

:::::::::::::::

 

in lisp -> create OMN with (midi-to-pitch)... 

 

(setq half-row (loop repeat 13
                 with interval
                 with stack = 60
                 with cnt = 0
                 when (oddp cnt) do (setq interval 13)  
                 when (evenp cnt) do (setq interval -11) 
                 when (= cnt 0) collect stack
                 else collect (setq stack (+ stack interval))
                 do (incf cnt)))

 

(midi-to-pitch (append half-row (reverse (butlast half-row))))

...technically, such pattern-match-things are - for my opinion - interesting when you write one value after the other (step by step with all paramters parallel), and then check all the time (every gen-cycle) the output on PATTERNS, and when there is a match you can change the gen-rules... 

 

data-structure with EVENTS like that...

 

(defstruct event duration pitch velocity rhy reading_rate optional_data)
(setf bot-1 (make-event))

...

 

and in every cycle you could write/GENERATE an EVENT

 

(Excerpt)

do (setf bot-1 (make-event 
                :duration data
                 :pitch (setq pitch-1 (nth seq-cnt-1 pitchfield))
                 :velocity (rnd-walk-in-chord '(1 0 -1) velocityfield velocity)
                 :rhy (rnd-walk-in-chord '(1 -1) rhyfield rhy-1)
                 :reading_rate 1; (rnd-pick'(1 2 3))
                 :optional_data (rnd-pick '(a b c d e))))

 

and then you check it (every cycle) for patterns... and if MATCH you could change the GEN-part the GEN-rules

...

 

like a small robot who tries "to move in the world or to recognize the world"...

dear rangarajan

 

i think the motif-map-function has a PATTERN-MATCH inside, but it "replaces the MATCH", (like in a contextual-rewrite), but perhaps i don't use the name/expression "pattern-match" in a wright/correct way... i'm more composer/musician then programmer :-)

here's a very basic example for am SIMPLE/PURE PATTERN MATCH:
a rnd-gen-value-list (to show how you could use it), with a PATTERN-MATCH-prog who scans it. 
the next value - after a complete match - will be changed into a rest... but you also could start a sub-function then who do what ever you want...? (when you change the code)

 

in a concrete project i coded it also in a more complex way - kind of "nontrivial-machines" (as an experiment) -> PATTERNmatch in pitches changes the DURATIONS, PATTERNmatch in durations changes pitches or timbre... and so on... like a "dynamic-interaction-network"...

 

sorry for my bad english...

FUNCTION - FOR A SIMPLE EXAMPLE

(defun pattern_cogn (liste pattern) 
  (loop for z in liste
    with cnt = 0
    with pattern_cnt = 0
  
    collect z   
    
    ;;;check a value - if it's a match -> incf counter
    when (or (eq  (nth cnt pattern) z)  (eq '? (nth cnt pattern)))
    do (incf pattern_cnt)
    and do (incf cnt)
    else do (setq cnt (setq pattern_cnt 0))
    
    ;;; if the pattern is MATCHED (=> counter = length pattern)  -> the output changes ... for example, the next value will be a rest
    ;;; = consequence
    when (eq pattern_cnt (length pattern))
    collect (* z -1)
    and do (setq cnt (setq pattern_cnt 0))))

 

FUNCTION-EVAL

(pattern_cogn (loop repeat 100
                collect (1+ (random 5))) ; generates rnd-values ->  TO SEARCH IN IT
              '(4 ? 2)) ; pattern to search (here with wildcard)

 

WHEN PATTERN MATCH THEN NEXT VALUE (* -1)

short question (i didn't read the whole documentation)... when i use/work with pattern-matching, i've done it with WILDCARDS ... is there any aspect of that in the motif-map function? or is a "ordinary pattern-matching-function" in OM?

 

like that: pattern to search/replace 

'(0 1 ? 3)

 

this is musically interesting, because it works with "fuzziness"....

 

regards,

andré

 

 

okay, i understand... i'm "not working" with '(q e q...), i'm always working with NUMBERS (with pitches too). it's easier to write/handle the values, easier to do my own specific code (and multipy, add... whatever) - only on "def-score" i'm changing the representation by generating OMN...

 

regards,

andré

you could do it like this on "pure-LISP-level"

(setf lengths '(1/4 2/8 3/8 4/4))

(loop for i in lengths
  with repl = (random (length lengths))
  for cnt = 0 then (incf cnt)
  when (= cnt repl) collect (* i -1)  else collect i)

 

best wishes

andré

short question...

when will the "tuplet-bugs" be fixed...it's  not possible for me to work with this bug...

thanx a lot

andré

cool!!!! :-) thanx!!!

 

it don't works!? no score-display

 

> Error: OMN Parse Error: fail
> While executing: omn-to-ast, in process Listener-1(7).
> Type cmd-. to abort, cmd-\ for a list of available restarts.
> Type :? for other options.

perhaps with a non-overlapping structure of the voices? 

and perhaps the tuplet-5/tuplet-3 will be shown as tuplet-15...

ok, thanx! i see my "wishes" are a little bit special - but perhaps OPUSMODUS can do that (without ties... or...)

hi all

 

i would like to MERGE/FIT the following 3-layer-voices(-EXAMPLE) into a ONE-layer-voice (with complex rhythms) - is it possible in OPUSMODUS?

thanx for help!

andré

 

EXAMPLE:

(setf voices (merge-voices (make-omn :length (gen-length '(1 2 3 4 5 6 7 8) 1/20)
                                     :pitch '(c4)
                                     :velocity '(pppp ppp pp p))
                           
                           (make-omn :length (gen-length '(1 2 3 4 5 6 7 8) 1/8)
                                     :pitch '(c5)
                                     :velocity '(pppp ppp pp p))
                           
                           (make-omn :length (gen-length '(1 2 3 4 5 6 7 8) 1/12)
                                     :pitch '(c6)
                                     :velocity '(pppp ppp pp p))))

(def-score example
           (:key-signature 'atonal
                           :time-signature '(4 4)
                           :tempo '(96)
                           :layout (treble-layout '3-layers))
 (3-layers
  :omn voices
  :channel 1
  :sound 'gm
  :program 1))

more informations: bug (with the 1/20) only when i start with a pitch. when the first value is a rest everthing seems to be okay!

interesting bug: have a look at the 1/20-layer (c6) -> midi sounds correct (!), notation is wrong

 

;;;;;;;;;;;;;;;;;;;;

(setf duration1 '(8 5 3 2 3 5 8))
(setf duration2 '(8 5 3 2 3 5 8)) 
(setf duration3 '(8 5 3 2 3 5 8))

(setf voices (merge-voices (make-omn :length (gen-length duration1 1/20)
                                     :pitch '(c6))
                           (make-omn :length (gen-length duration2 1/32)
                                     :pitch '(b4))
                           (make-omn :length(gen-length duration3 1/8)
                                     :pitch '(as2))))

           (:key-signature '(c maj)

                           :tempo '(60))
  
  (piano
   :omn voices
   :channel 1
   :sound 'gm
   :program 0))

(display-midi (compile-score 'voices) :display :quick-view)

 

;;;;;;;;;;;;;;;;;;;;

 

thanx, but midi don't like such VALUES  :-( - so it works only for notation (or sibelius/finale)...

 

for the future it would be nice for my work (and perhaps interesting for other composers), when the time/rhythm-things could be more flexible - i think the biggest bounderies in opusmodus are the time/rhythm-things and it's notation (paper/pencil is the most flexible way, and i don't want to be a limited by software). if you work really "experimental" you want to map rhythm-values in a complexer way...

 

for me it would be great and very nice, when it would be possible to notate/play such rhy-sequences like '(1/4 1/4 1/12 1/12 3/16 1/16....) with values that are not completing 1/4. at the moment OPUSMODUS is "correcting" this... (would be nice to have irregular time-signatures or bars with no time-signature!!!)....  

 

in my work for example: i have programmed BOTS/non-trivial-machines, who are generating values "step-by-step" and the inner-state of the non-trivial-machine always changes its datas/memory (in a rnd-way). the result is, that the rhythm-values all the times are changing (more or less like in the special-bars-examples). and because it's not possible to calculate the output of the non-trivial-machine (that's the natural constitution of them), it's not possible to "fit the rhyhm-values" into prefiexed-bar-structures. that's a problem for my work and so i have to write such strange programs who fix the complicated rhy-changes :-)

 

thanx for your great work!!!

andré

 

a solution: perhaps it's interesting for anyone (or as an example for OPMUSMODUS-implementation) - a simple function (programmed by a friend and myself)  - not very smart but it (should) work(s) :-)

thanx for the anwser...

first example: it's possible to do this, i can realize with "special-bars" like 2/3 or 5/20 - by a little (self-made) lisp-function - so it works...

 

seems to be a bug...

evaluate this: 

(make-omn
         :pitch '(c5 c3 c2 c3 c4)
         :length '(-2/12 2/12 -1/12 6/12 -1/12 3/12 1/12)                           
         :velocity '(mf))

 

after the 6/12 the next value -1/12 is shown as -1/8 in the score

score 

when i evaluate this:

(make-omn
         :pitch '(c5)
         :length '(3/12 -1/12 4/12 -1/20 3/20 1/20)                           
         :velocity '(mf))

 

the result is wrong (look at (3/12 -1/12 4/12).... but i would like to notate something like valeur ajoutée

isn't it possible? thanx a.

thanx, that's the way it works

little lisp-problem/question with &optionel / &key... 

here are two test-programs to explore keyword and optional paramters

 

 

this test-program works

 

(defun test1 (liste  add  &key (add-on/off))

  (loop for i in liste 

    when (equal add-on/off 'on)

    collect (+ i add)

    else collect i))

 

(test1 '(1 2 3 4 5) 100 :add-on/off 'on)

 

 

this version with &optional don't work... why? 

 

(defun test2 (liste  add &optional (x 10) &key (add-on/off))

  (loop for i in liste 

    when (equal add-on/off 'on)

    collect (+ i add x)

    else collect i))

 

(test2 '(1 2 3 4 5) 100 :add-on/off 'on)

thanx for help

i will write a little function and post it at the forum later.

yes, that's the way it will works... only one little "problem"...

 

the pitch will be always different... so the search-pattern should be something like '(e ?) -> to '((acc ?) -> pitch sould be overtaken to (acc ?), i only want to replace the length-val to an acc..
