AM Posted March 6, 2016 Share Posted March 6, 2016 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.

AM Posted March 6, 2016 Author Share Posted March 6, 2016 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 Quote Link to comment Share on other sites More sharing options...
opmo Posted March 6, 2016 Share Posted March 6, 2016 The system will display your expression: (make-omn :pitch '(c5) :length '(3/12 -1/12 4/12 -1/20 3/20 1/20) :velocity '(mf)) even the tuplets are not completed. As for the second post, yes this is a bug. Quote Link to comment Share on other sites More sharing options...
AM Posted March 6, 2016 Author Share Posted March 6, 2016 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... Quote Link to comment Share on other sites More sharing options...
AM Posted March 6, 2016 Author Share Posted March 6, 2016 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) :-) greetings a. (defun time-sign-changes (durations rhys &key (complex-bars 'nil)) (if (equal complex-bars 'nil) (loop for i in durations for j in rhys with sum = 0 with last-j = (first durations) when (and (/= j last-j) (/= sum 0)) collect (list (numerator sum) (denominator sum) 1) into bag and do (setq sum 0) do (setq sum (+ sum (abs (* i j)))) when (> sum 1/4) collect '(1 4 1) into bag and do (setq sum (- sum 1/4)) do (setq last-j j) finally (return (append bag (list (list (numerator sum) (denominator sum) 1))))) (loop for i in durations for j in rhys with sum = 0 with last-j = (first durations) when (and (/= j last-j) (/= sum 0)) collect (list (numerator sum) (denominator sum) 1) into bag and do (setq sum 0) do (setq sum (+ sum (abs (* i j)))) when (> sum 1/2) collect '(1 2 1) into bag and do (setq sum (- sum 1/2)) do (setq last-j j) finally (return (append bag (list (list (numerator sum) (denominator sum) 1))))))) (setq durations '(-1 2 3 4 3 2 -5 4 3 2 4 3 1 7)) (setq rhythms '(1/32 1/32 1/32 1/32 1/20 1/20 1/20 1/20 1/20 1/12 1/12 1/12)) ;;creating the lengths (setq lengths (loop for i in durations for j in rhythms collect (* i j))) ;; creating the bar-changes -> :complex-bars 'nil or 't (setq bars (time-sign-changes durations rhythms :complex-bars 'nil)) (def-score solo (:title "example" :key-signature 'atonal :time-signature bars :tempo '90 :layout (treble-layout 'example)) (example :omn (make-omn :pitch '(c4) :length lengths) :channel 1 :volume 100 :sound 'gm)) Quote Link to comment Share on other sites More sharing options...

AM Posted March 7, 2016 Author Share Posted March 7, 2016 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 Quote Link to comment Share on other sites More sharing options...
opmo Posted March 7, 2016 Share Posted March 7, 2016 I will look into it soon. Quote Link to comment Share on other sites More sharing options...
