    rest-diminution/augmentation

    i needed functions which shorten/enlarge only the RESTS of my complex/tupled-mixed texture - not precisely - so i coded it with diminution/augmentation+round (otherwise i would be in trouble by the crazy rests)... violà... use it or code it smarter for OMPO! greetings andré 3 functions: rest-diminution rest-augmentation only-length-augmentation ;;; (defun rest-diminution (omnlist &key (factor 1) (round 1/4)) (length-rest-merge (flatten (loop for i in (single-events (length-rest-merge omnlist)) when (< (car (omn :length i)) 0) collect (length-rational-quantize (length-diminution factor i) :round round) else collect i)))) (rest-diminution '(-3q q e4 mp -w e e4 ff) :factor 3 :round 1/4) => (-q e4 mp -h e e4 ff) (rest-diminution '(-3q q e4 mp -w e e4 ff) :factor 3 :round 1/8) => (-e q e4 mp -q. e e4 ff) ;;; (defun rest-augmentation (omnlist &key (factor 1) (round 1/4)) (length-rest-merge (flatten (loop for i in (single-events (length-rest-merge omnlist)) when (< (car (omn :length i)) 0) collect (length-rational-quantize (length-augmentation factor i) :round round) else collect i)))) (rest-augmentation '(-3q q e4 mp -w e e4 ff) :factor 3 :round 1/4) => (-q e4 mp -d. e e4 ff) (rest-augmentation '(-3q q e4 mp -w e e4 ff) :factor 3 :round 1/8) => (-q e4 mp -d. e e4 ff) ;;; (defun only-length-augmentation (omnlist &key (factor 1) (round 1/4)) (length-rest-merge (flatten (loop for i in (single-events (length-rest-merge omnlist)) when (> (car (omn :length i)) 0) collect (length-rational-quantize (length-augmentation factor i) :round round) else collect i)))) (only-length-augmentation '(-3q q e4 mp -w e e4 ff) :factor 3 :round 1/8) => (-3q h. e4 mp -w q. e4 ff) (only-length-augmentation '(-3q q e4 mp -w e e4 ff) :factor 3 :round 1/4) => (-3q h. e4 mp -w q. e4 ff -e)
