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...
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)
when will the "tuplet-bugs" be fixed...it's not possible for me to work with this bug...
thanx a lot
cool!!!! :-) thanx!!!
it don't works!? no score-display

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...)
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!
(setf voices (merge-voices (make-omn :length (gen-length '(1 2 3 4 5 6 7 8) 1/20)
:velocity '(pppp ppp pp p))
(make-omn :length (gen-length '(1 2 3 4 5 6 7 8) 1/8)
:velocity '(pppp ppp pp p))
(make-omn :length (gen-length '(1 2 3 4 5 6 7 8) 1/12)
:velocity '(pppp ppp pp p))))
:time-signature '(4 4)
:layout (treble-layout '3-layers))
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)
(make-omn :length (gen-length duration2 1/32)
(make-omn :length(gen-length duration3 1/8)
(:key-signature '(c maj)
:time-signature '(4 4)
(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!!!
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) :-)
(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))
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...
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.
what's new/different in Opusmodus 1.1.18273
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 listewhen (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 listewhen (equal add-on/off 'on)collect (+ i add x)else collect i))(test2 '(1 2 3 4 5) 100 :add-on/off 'on)> Error: While compiling test2 :
> Bad lambda list : (liste add &key add-on/off &optional (x 10)), in process Listener-1(7).thanx for helpandré
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..
simple question, perhaps someone could help me.
i like to replace some ordinary notes (example) with an "acciaccatura"?
'((e c6 q. ab5 3e g5 f5 e5 q f5 -))
'((acc c6) q. ab5 3e g5 f5 e5 q f5 -) ; = replace e c6 with (acc c6)
i think, its not complicated but i didn't found the OMN-solution.
thanx for your help!!
a solution could be... to write the cents (-14) or what ever as TEXT-file above each note - so you could work with it in sibelius/finale/paper
POLYTEMPO: would be great and very interesting! here is the technology to do/perform this LIVE on STAGE... http://www.smc-conference.net/smc-icmc-2014/images/proceedings/PS2-B03-PolytempoNetwork.pdf. (by philippe kocher - institute for computer music and sound technology zurich university of art).
it works simple and fantastic!!
MICROTONAL: i prefer (q c4.0456) but i would like more (or as an option) 60.0456 (via midi-note-number), so you could work/calculate directly with numbers and "pure lisp-code"....
it works in PWGL, not really for notation but i can listen/programm/simulate polytempo-scores in midi (or other players). so i could transfer my lisp-code to pwgl-boxes... etc...
but i would be nice, if i could do it in OPUSMODUS, no boxes etc... :-)
Doubt about motif-map function
in Support & Troubleshooting
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
this is musically interesting, because it works with "fuzziness"....
