Merge-voices from list

[vpolajnar]

Dear Opmo users, i would like to merge voices from one single list. So I would like this (not-working) merge-voice function:

(setf test '((s) (-s s) (-e s)))
(merge-voices test)

To work like this:

(merge-voices '(s) '(-s s) '(-e s))

 

 

Does anyone has an Idea how to achieve it?

 

Best,

Vili

merge-voices function is made for OMN expressions, not length lists.

Dear Stephane,

 

thank you, even if try with "OMN expressions" in a list , if i understand it correctly, is pretty same.

 

(setf test '((s c4) (-s s c4) (-e s c4)))

(merge-voices test)
(merge-voices '(s c4) '(-s s c4) '(-e s c4))

 

But anyways, does anyone knows how this function is programmed so I could program own one, with result I wanna achieve.

 

 

Best,

 

Vili

some "ugly code" ...but it works.... 

you want to use (merge-voices) with ONE list as input?

 

(setf test '((w c2) (h c4 d4) (q g5 g5 g5 g5)))

(defun your-merge-voices (alist) 
          (merge-voices (first alist) 
                        (second alist) 
                        (third alist) 
                        (fourth alist) 
                        (fifth alist)))

(your-merge-voices test)

Dear friends,

 

I got the result

 

(z^w c2 z^h c4 q g5 g5 z^h d4 q g5 g5)

 

in this operation, using André´s function. What is the meaning of z and ^ in the OMN language ?

 

THanks,

best,

Julio

Common Lisp's APPLY function applies the function of the first argument to the remaining arguments.

 

(setf test '((s c4) (-s s c4) (-e s c4)))
(apply #'merge-voices test)
=> ((s c4) (s c4) (s c4))

oh, thx, did not know, that APPLY works on functions "first to the remaining arguments."!

This is OM polyphonic notation.

Thanks, Stephane !!

 

Is there some documentation about it ? 

Very good to know.
