  1. hi, yes - with this two functions (get-posititon & inserting-on-bar/beat*) you will have a lot of possibilities... 1) post-processing an OMN without changing the global time structure 2) working with "strukturnetze" (lachenmann) 3) countrepoints 4) idea of palimpsts .... ...so, perhaps OPMO could code it smarter then me (that's not complicated :-))? ... i try to do an example today with something like a "strukturnetz"

  3. hi all the following function could be usefull, it's a first sketch, but it seems to work.... if you want to INSERT a new OMN-seq, perhaps in bar 2 on the 3/20 in your BASIC-OMN-sequence... with this function you can do this, it will overwrite your original phrase. test it or tell me whatelse would be better... greetings andré ;;; ------------------------------------------------------------------------ ;;; INSERTING SEQ BY OVERWRITING ;;; ------------------------------------------------------------------------ ;;; SUB (defun get-resolution2 (beat) (cond ((memberp (cadr beat) '(3 6 12 24 48)) 1/24) ((memberp (cadr beat) '(1 2 4 8 16 32)) 1/16) ((memberp (cadr beat) '(5 10 20 40)) 1/20) ((memberp (cadr beat) '(7 14 28 56)) 1/28))) ;;; MAIN: INSERTING SEQ BY OVERWRITING (defun inserting-on-bar/beat* (seq &key insert time-sign bar beat) (let ((resolution (get-resolution2 beat)) (ord-time-sign time-sign) (time-sign (if (listp (car time-sign)) (loop for i in time-sign when (> (caddr i) 1) append (loop repeat (caddr i) collect (list (car i) (cadr i))) else collect (list (car i) (cadr i))) (append time-sign))) (distance (if (listp (car time-sign)) (+ (car (loop repeat (- bar 1) for i in time-sign collect (/ (* (1- bar) (/ (car i) (cadr i))) (get-resolution2 beat)))) (/ (/ (1- (car beat)) (cadr beat)) (get-resolution2 beat))) (+ (/ (* (1- bar) (/ (car time-sign) (cadr time-sign))) (get-resolution2 beat)) (/ (/ (1- (car beat)) (cadr beat)) (get-resolution2 beat)))))) (omn-to-time-signature (omn-merge-ties (flatten (loop repeat (length (omn-to-time-signature seq (list (numerator resolution) (denominator resolution)))) for cnt = 0 then (incf cnt) with new-seq = (omn-to-time-signature seq (list (numerator resolution) (denominator resolution))) with insert-rounded = (append insert (rest (length-rational-quantize (list (apply '+ (omn :length insert))) :round resolution))) when (= cnt distance) collect insert-rounded and do (setf cnt (+ (/ (get-span (flatten insert-rounded)) resolution) cnt -1)) else collect (nth cnt new-seq)))) ord-time-sign))) ;;; EXAMPLES (inserting-on-bar/beat* '((e c6 a5 h b5 tie) (q b5 b5 a5 tie) (h a5 q a5) (h. g5)) :insert '(s f3 e3 eb3 d3) :time-sign '(3 4) :bar 2 :beat '(2 16)) (inserting-on-bar/beat* '((e c6 a5 h b5 tie) (q b5 b5 a5 tie) (h a5 q a5) (h. g5)) :insert '(3q c5 b4 bb4 a4) :time-sign '(3 4) :bar 1 :beat '(2 12)) ;;; EXAMPLE WITH different TIME-SIGNATURES (inserting-on-bar/beat* '(e c6 a5 h b5 tie q b5 b5 a5 tie h a5 q a5 h. g5) :insert '(5q c5 b4 bb4 a4) :time-sign '((2 4 1) (3 8 1) (5 8 1) (3 4 1)) :bar 3 :beat '(3 20))

  10. an idea/extension could be to "filter-events" not only by singular pitches/lengths... but also by motifs, means sequences => "filter a PATTERN" function-name: filter-pattern

    great work! hm, i would be nice, if i could add a optional fifhth/sixth/seventh-value to (l p v a)... in reality - for example - i want to split DIVISI-strings into parts, or splits 100 clarinets (because they are placed around the audience), or something else... this would be possible with opt.args... :-)

    Fibonacci

    looks like adding intervals? ...code it! :-)
  17. data could also be midi-channel, prog-number....
  18. i see and unterstand what you mean... (as a non-programmer :-)), so i'm asking here some naive questions: a) isn't it better to "seperate" the BASIC-OMN-structure from the additionals? in a way, i'm more independet if OPMO changes some things? b) in my way i see completely transparent and easy what's up, and not a mixture of text-attributes/data...? c) if I could change the OPMO SINGLE-EVENTS-structure, i would extend it like I did ...and not mixing it, isnt' it much more "logic" (but perhaps not for a programmer-brain :-)) ...but... it is great to have such good inputs, that's what i'm looking for in this FORUM, thanx a lot torsten!!! herzlich andré added 8 minutes later in my view it would be nice to EXTEND the "make-omn/single-events"-structure by x-add-datas... like: (make-omn :length :pitch :velocity :articulation :data1 :data2 ... ... ...)
  19. if you want to control the global-pitch-progress, and not making/writing all length-list by hand you have to work/think (imo) with EVENTS (in opmo (single-events)), otherwise you will have all the time "random-stuff" or have incorrect synchronisations... but perhaps this is what you are looking for... all the best andré
