Sort Pitches with lengths

[Pietro Bonanno]

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 to the program.

 

Thank you a lot!

Hi,

 

this could be a solution:

 

(setf orig '((h c6 mp) (w. f5 pp) (d a4 mp)))

(defun prepa (lst)
  (car (pitch-to-integer (omn :pitch lst))))

; test of prepa:
(prepa '(h c6 mp))

(setf ordered (sort (copy-seq orig) #'< :key #'prepa))

SB.

Thank you a lot. It's EXACTLY what I need!
