In Lesson 4, it is statet that "You can see the LENGTH-WEIGHT replaces previously 'sounding' lengths with rest-lengths throughout the stream of pitches. "
But  actually Length-Weight  INSERTS rests. Sounding pitches are not replaced, but shiftet.
Is that correct?

 

To swallow pitches use GEN-SWALLOW function:

(gen-swallow '(1/4 -1/4 1/4 -1/4) '(c4 d4 e4 g4))

All depends on the stage you are using the LENGTH-WEIGTH function and what you want to achieve.

Anyway, I could add the swallow process into the function.

What does that mean?

Is the input omn form or just a length values, this is what I was saying and at what stage of your composition you used the function.

Adding  'swallow' to LENGTH-WEIGHT function would be appreciated here 😉

The additional swallow keyword (default t) will be part of the next release. 🙂

(length-weight '((q c4 d4 e4 f4 g4 a4 b4)
                 (q c4 d4 e4 f4 g4 a4 b4))
               :weight '((3 1) (5 2))
               :swallow nil
               :seed 875)
=> ((q c4 d4 e4 f4 g4 - a4) (q c4 d4 - e4 f4 g4 -))

;; With :swallow T (default)

(length-weight '((q c4 d4 e4 f4 g4 a4 b4)
                 (q c4 d4 e4 f4 g4 a4 b4))
               :weight '((3 1) (5 2))
               :seed 875)
=> ((q c4 d4 e4 f4 g4 - b4) (q c4 d4 - f4 g4 a4 -))

great !

Very important for keeping pitch alignment between 2 or more voice for counterpoint control !!
