Hi,

I want the following rhymical structure of tied length values ( see attached .jpg). When I write it like this:

(setf laengen-oben-zwei '((q. e tie) (q 3q 3q_3q_q. e tie) (q. e_h tie) (e q._h)))

the ties are ignored by the mapping

see:

(setf laengen-oben-zwei '((q. e tie) (q 3q 3q_3q_q. e tie) (q. e_h tie) (e q._h)))
(setf toene-oben-zwei '(c4 d4 e4 fs4 gs4 bb4))

(make-omn 
 :length laengen-oben-zwei
 :pitch toene-oben-zwei)

how can I express the length-values so that the ties are taken in account?

thanks for a hint!

TIE can't be used in length alone.

TIE is part of OMN form (grammar).

You need to rewrite your lengths without the TIE attribute.

You could do:

(setf laengen-oben-zwei '(q. e_q 3q 3q_3q_q. e_q. e_h_e q._h))
(setf toene-oben-zwei '(c4 d4 e4 fs4 gs4 bb4))

(setf mat
      (make-omn 
       :length laengen-oben-zwei
       :pitch toene-oben-zwei))

(omn-to-time-signature mat '(4 4))

Of course you can use the time signature on the DEF-SCORE level :-)

like this?

(setf laengen-oben-zwei '((q. e_q 3q 3q_3q_q. e_q. e_h_e q._h)))

and than define the 4/4 in the score section?

The _ tie is fine. The time signature you will define in DEF-SCORE section.

Overlooked half of your reply! Thanks for the pointer to the

omn-to-time-signature function. Very handy!
