AM Posted October 19, 2018 Share Posted October 19, 2018 (edited) with these functions you could write your CENTS for tuning directly into OMN-attributes, and extract it afterwards 1. generate by add-cents-tuning-to-text-atrributes the cent values into text-attributes (only one time), you could decide if it will be shown in the score "as CENTS or as FLOAT" 2. now you could write your CENTS for tuning into OMN-attributes like 50ct, -34ct ...also in combination with other text-attributes legno+50ct, pizz+-65ct, -45ct+batt 3. you could EXTRACT afterwards your LIST for TUNING directly from OMN by get-tuning-from-omn*.if an EVENT has no cent-attribute it will be unchangend (= 0 cents) ;;; ------------------------------------------------------------------------------------------------------------------- ;;; ------------------------------------------------------------------------------------------------------------------- ;;; this function adds CENTS or FLOATS to text-attributes, in this way you can notate ;;; - have a look how it's written in the score -> all combinations of attributes possible ;;; ------------------------------------------------------------------------------------------------------------------- ;;; ------------------------------------------------------------------------------------------------------------------- (defun add-cents-tuning-to-text-atrributes (&key (centlist nil) (type nil)) (loop for i in (loop for x in (if (null centlist) (append (loop for i from 0 upto 99 collect i) (loop for i from 1 upto 99 collect (neg! i))) centlist) collect (compress (list x 'ct))) append (add-text-attributes (list i (write-to-string (if (equal type :float) (float (/ (append (compress (if (equal (car (explode i)) '-) (if (= (length (explode i)) 5) (filter-first 3 (explode i)) (filter-first 2 (explode i))) (if (= (length (explode i)) 4) (filter-first 2 (explode i)) (filter-first 1 (explode i))) ))) 100)) i)))))) ;;; EXAMPLES (add-cents-tuning-to-text-atrributes :type :float) ;; have a look to notation: cmd3 (-q -q e c4 fff q c4 mf 50ct e c4 mf -40ct e c5 ff) (add-cents-tuning-to-text-atrributes :type :cents) ;; cents are written ;; have a look to notation: cmd3 (-q -q e c4 fff q c4 mf 50ct e c4 mf -40ct e c5 ff) ;;; ------------------------------------------------------------------------------------------------------------------- ;;; ------------------------------------------------------------------------------------------------------------------- ;;; this function get out all notated microtones for TUNING ;;; if there is nothing written it will be 0 cents (0) ;;; you can combine all kinds of attributes ;;; ------------------------------------------------------------------------------------------------------------------- ;;; ------------------------------------------------------------------------------------------------------------------- (defun memberp (n liste) (not (equal 'nil (member n liste)))) (defun find-duplicates (lst) (cond ((null lst) '()) ((member (car lst) (cdr lst)) (cons (car lst) (find-duplicates (cdr lst)))) (t (find-duplicates (cdr lst))))) (defun get-tuning-from-omn* (omnlist centlist) (loop for i in (single-events (length-rest-remove omnlist)) with n = 0 when (not (null (find-duplicates (append (disjoin-attributes (car (last i))) centlist)))) do (setf n (float (/ (append (compress (remove-if-not #'numberp (explode (car (find-duplicates (append (disjoin-attributes (car (last i))) centlist))))))) 100))) and collect (if (equal (car (explode (car (find-duplicates (append (disjoin-attributes (car (last i))) centlist))))) '-) (* -1 n) n) else collect 0)) ;;; EXAMPLES (setf centlist (add-cents-tuning-to-text-atrributes :type :float)) ;;; evaluate this and you will get the tuning-list with all combinations of attributes (get-tuning-from-omn* '(-q -q e c4 fff q c4 mf legno+50ct+num1 e c4 mf -50ct+legno+batt e c5 ff pizz+-34ct) centlist) => (0 0.5 0.5 -0.34) (get-tuning-from-omn* '(-q -q e c4 fff -34ct+pizz q c4 mf legno+50ct e c4 mf -50ct+legno+batt e c5 ff pizz+-34ct) centlist) => (-0.34 0.5 -0.5 -0.34) (get-tuning-from-omn* '(-q -q e c4 fff -34ct+pizz+num11 q c4 mf legno+50ct e c4 mf -50ct+legno+batt e c5 ff pizz+-34ct) centlist) => (-0.34 0.5 -0.5 -0.34) ;;; cmd3 for LAYOUT/SCORE (-q -q e c4 fff -34ct+pizz+num11 q c4 mf legno+50ct e c4 mf -50ct+legno+batt e c5 ff pizz+-34ct) (-q -q e c4 fff q c4 mf legno+50ct+num1 e c4 mf -50ct+legno+batt+num2 e c5 ff pizz+legno+-34ct) Edited October 20, 2018 by AM a small change - now you can write also 0ct for no detuning opmo 1 Quote Link to comment Share on other sites More sharing options...

opmo Posted October 20, 2018 Share Posted October 20, 2018 The future pitch (v1.4) will look like: c4 c4[50] fs4[50] d6[-30] etc... chord c4fs5[50] Every cents value which falls into microtonal notation (50, 30 -50 -75 ...) will be part of the notation all others will be written above the note: -43c lviklund, torstenanders, AM and 1 other 4 Quote Link to comment Share on other sites More sharing options...
