Hello,

 

I am trying to assign articulations (attributes) to certain note lengths

 

my attempt:

(setf omn '((q e3 p -q s a4) (s f3 mp -s) (e g3 mf)))
(setf rh (omn :length omn))
;=> ((1/4 -1/4 1/16) (1/16 -1/16) (1/8))

;; how is it possible to convert the ratios to omn-notation?:
(setf rhomn '((q -q s) (s -s) (e)))

(setf aq '(ord)
      as '(stacc)
      ae '(spicc)
      a-q '(-)
      a-s '(-))

(setf art (assemble-section 'a (flatten rhomn)))

;;I don't understand how to handle the rests

(setf pch (omn :pitch omn))
(setf vel (omn :velocity omn))

(make-omn :length rh
          :pitch pch
          :velocity vel
          :articulation art)
; => ((q e3 p ord - s a4 ord) (s f3 mp -) (e g3 mf stacc))

 

Which method can I use to achieve the correct assignment of the attributes to the specific note lengths, in order to obtain this result?

((q e3 p ord -q s a4 stacc ) (s f3 mp stacc -s) (e g3 mf spicc))

 

Thank you very much for any help or advice you can give me,
best wishes

One solution would be:

 

(setf omn '((q e3 p -q s a4) (s f3 mp -s) (e g3 mf)))

(setf dictum '((:any q :apply ord)
               (:any e :apply spicc)
               (:any s :apply stacc)))

(dictum dictum omn)
=> ((q e3 p ord - s a4 stacc) (s f3 mp stacc -) (e g3 mf spicc))

 

Another solution is also possible with the function length-map:

(setf omn '((q e3 p -q s a4) (s f3 mp -s) (e g3 mf)))

(setf out (length-map '((q ord)(s stacc)(e spicc)) omn))
=> ((q e3 p ord - s a4 stacc) (s f3 mp stacc -) (e g3 mf spicc))

 

Thank you very much for your fast and helpful answers!
