I wonder if there's a function to allow for systematic transformations of rhythmic streams, like in the example below. From a regular stream of 16th notes: (s c4 d4 e4 f4 5q d4 e4 f4 g4 e4 s f4 g4 a4 f4 3q g4 a4 b4) To occasional introduction of quintuplets, tuplets, etc: (s c4 d4 e4 f4 5q d4 e4 f4 g4 e4 s f4 g4 a4 f4 3q g4 a4 b4) Or: (6q c4 d4 e4 f4 d4 e4 s f4 g4 f4 g4 5q a4 f4 g4 a4 b4) Thank you!

;;; ADD-RND-DUST TO LENGTHS ;;; this function adding RANDOMLY some "dust" to the LENGTHS, so it will be like a little rubato, ;;; or "humanizing"-effect. the ADD-SPAN is in percent (0.1 = 10%) on each length-value. (defun add-rnd-dust (omnseq &key (span '(0.1)) (seed nil) (quantize '(1 2 3 4 5 6 7 8 9))) (let ((rhy (omn :length omnseq)) (sp)) (progn (setf rhy (loop with cnt = 0 for i in rhy do (setf sp (nth cnt span)) when (not (null seed)) do (incf seed)

Good morning. I'm interested in score analysis and I've encountered an issue. Is it possibile in Opusmodus, after I've create a score in OMN form (for example : (h c6 mp) (w. f5 pp) (d a4 mp) ) sort these sublist in PITCH ascending order linking the corresponding value of LENGTH? example: convert this: (h c6 mp) (w. f5 pp) (d a4 mp) in this: (d a4 mp) (w. f5 pp) (h c6 mp) where every sublist remains the same but the order is changed on a pitch base (in this case ascending). I've tried SORT-ASC and similar, but probably there's something to try and I'm new

Hi, How can I find the sum of lengths in OMN including rests? Obviously the code below won't work, but it will give you an idea what I'm looking for: (setf anacrusis-ls '((-s = = = = = = =) (-3e = = = = =) (-5q. = = = = = = = = =))) (setf pick (rnd-pick anacrusis-ls)) (setf sum (find-sum pick)) All the best, Erik
