AM Posted December 2, 2017 Share Posted December 2, 2017 (edited) i didn't find a OM-library-solution for this kind of thing, so i coded it... if you want to REPLACE the articulation of some specific pitches. perhaps all 'd4 sould be PONTE... you could use this. it was necessary to code it like that, because otherwise you get in trouble with the empty parameter-slots... should work fine greetings andré ;;; SUBFUNCTIONS (defun eliminate-nil (alist) (loop for i in alist when (not (null i)) collect i)) (defun complete-event-slots (omn-list) (let ((omn-art (omn :articulation (single-events (flatten omn-list))))) (single-events (omn-replace :articulation (flatten (eliminate-nil (loop for i in omn-art for cnt = 0 then (incf cnt) when (equal (car i) '-) collect (nth (1- cnt) omn-art) else collect i))) omn-list)))) ;(complete-event-slots '(5q a4 ff pizz 5q e3 -e 5q a4 f)) ;;; MAIN FUNCTION (defun replace-articulation-of-a-pitch (omn-list &key pitches articulation (chance 1.0)) (loop for i in (complete-event-slots (flatten omn-list)) when (and (member (car (omn :pitch i)) pitches) (prob? chance)) append (omn-component-replace i (list articulation)) else append i)) ;;; EXAMPLE (replace-articulation-of-a-pitch '(5q a4 ff pizz 5q e3 p -q 5q d4 pizz) :pitches '(a4 d4) :articulation 'ponte :chance 1.0) -> (5q a4 ff ponte 5q e3 p pizz -q 5q d4 p ponte) Edited December 3, 2017 by AM missing subfunction, now changed opmo 1 Quote Link to comment Share on other sites More sharing options...
