  1. Here's a new function a bit similar to my old "add-interval-if-length" function but bit more sophisticated. It use gen-chord3 to create chord on defined length. ;;; ============================================== ;;; UTILITY FUNCTIONS ;;; (defun make-chord-if-length-aux (omn &key (test #'>) (length-val 1/8) (interval-list '((4 7)(7 12))) (cycle t)(relative nil) seed) (setf seed (rnd-seed seed)) (let ((s-events (single-events omn))) (loop for e in s-events for i in (gen-trim (length s-events) interval-list) when (funcall test (omn-encode (first e)) length-val) append (omn-replace :pitch (gen-chord3 (list (second e)) i :cycle cycle :relative relative :seed (seed)) e ) else append e))) ;(make-chord-if-length-aux '(q c4 d4 e4 f4 e g4 a4)) ;(make-chord-if-length-aux '(q c4 d4 e4 f4 e g4 a4) :interval-list '((4 7)(3 10))) ;(make-chord-if-length-aux '(q c4 d4 e4 f4 e g4 a4) :interval-list '((4 7 11 14)(7 9 16)) :cycle nil) ;(make-chord-if-length-aux '(q c4 d4 e4 f4 e g4 a4) :interval-list '((4 7 11 14)(7 9 16)) :cycle nil :seed 4) ;(make-chord-if-length-aux '(q c4 d4 e4 f4 e g4 a4) :interval-list '((4 7 11 14)(7 9 16)) :cycle nil :relative t) ;(make-chord-if-length-aux '(q c4 d4 e4 f4 e g4 a4) :interval-list '((4 7 11 14)(7 9 16)) :cycle nil :relative t :seed 4) ;;; ============================= ;;; MAIN FUNCTION (defun make-chord-if-length (omn &key (test #'>) (length-val 1/8) (interval-list '((4 7)(7 12)))(cycle nil)(relative nil) seed) (setf seed (rnd-seed seed)) (do-verbose ("make-chord-if-length :seed ~s :length-val ~s :interval-list ~s :cycle ~s :relative ~s" seed length-val interval-list cycle relative) (let ((test-fn (case test (> #'>) (< #'<) (= #'=) (otherwise test)))) (if (listp (car omn)) (mapcar #'(lambda (x) (make-chord-if-length-aux x :test test-fn :length-val (omn-encode length-val) :interval-list interval-list :cycle cycle :relative relative :seed (seed))) omn) (make-chord-if-length-aux omn :test test-fn :length-val (omn-encode length-val) :interval-list interval-list :cycle cycle :relative relative :seed (seed)))))) ;;; Tests ;(make-chord-if-length '((q c4 e d4 e4 f4 h d4)(s a4 b4 a4 g4 h f4)(q c4 d4 h e4))) ;(make-chord-if-length '((q c4 e d4 e4 f4 h d4)(s a4 b4 a4 g4 h f4)(q c4 d4 h e4)) :seed 8) ;(make-chord-if-length '((q c4 e d4 e4 f4 h d4)(s a4 b4 a4 g4 h f4)(q c4 d4 h e4)) :interval-list '((2 9)(7 11))) ;(make-chord-if-length '((q c4 d4 e4 f4 g4)(s a4 b4 a4 g4 h f4)(q c4 d4 h e4)) :cycle t) ;(make-chord-if-length '((q c4 e d4 e4 f4 h d4)(s a4 b4 a4 g4 h f4)(q c4 d4 h e4)) :cycle nil :relative t) ;(make-chord-if-length '((q c4 e d4 e4 f4 h d4)(s a4 b4 a4 g4 h f4)(q c4 d4 h e4)) :cycle nil :relative t :seed 8) i've also attached the original file to this post.
