Posted January 10, 20214 yr Hi, I'am examin the distribute-seq function and don't get the exact logic behind it: (setf pitch '(c4 cs4 d4 ds4 e4 f4 fs4 g4 gs4 a4 as4 b4)) #| 1 2 3 4 5 6 7 8 9 10 11 12 |# (setf l-v1 '(1/8 -1/8 2/8 -1/8 5/8) l-v2 '(1/8 1/8 -1/8 2/8 1/8) l-va '(-2/8 1/8 -5/8 1/8) l-vc '(-1/8 3/8 1/8 1/8) ) (setf align (distribute-seq pitch l-v1 l-v2 l-va l-vc)) ==>((c4 e4 gs4) (cs4 d4 fs4 a4) (f4 b4) (ds4 g4 as4)) ;;;from the docs, what is the rule for the distribution (when the lists are of different size)? ;;;Do the list of pitches (have to) match the list of length values? #| -----------------that's what I would expect:------------------- 1 5 9 l-v1 '(1/8 -1/8 2/8 -1/8 5/8) 2 6 10 12 l-v2 '(1/8 1/8 -1/8 2/8 1/8) 3 7 l-va '(-2/8 1/8 -5/8 1/8) 4 8 11 l-vc '(-1/8 3/8 1/8 1/8) -----------------that's how it works:------------------------ 1 5 9 l-v1 '(1/8 -1/8 2/8 -1/8 5/8) 2 3 7 10 l-v2 '(1/8 1/8 -1/8 2/8 1/8) 6 12 l-va '(-2/8 1/8 -5/8 1/8) 4 8 11 l-vc '(-1/8 3/8 1/8 1/8) ----------------that's what Stéphane would expect (and what would also make sense to me): 1 6 11 l-v1 '(1/8 -1/8 2/8 -1/8 5/8) 2 3 8 12 l-v2 '(1/8 1/8 -1/8 2/8 1/8) 4 9 l-va '(-2/8 1/8 -5/8 1/8) 5 7 10 l-vc '(-1/8 3/8 1/8 1/8) |# greatful for some insight, thanks! ole
January 10, 20214 yr This will explain the delta time pitch distribution. 🙂 (ps 'gm :va (list '(1/8 c5 -1/8 2/8 -1/8 5/8) '(1/8 g4 1/8 -1/8 2/8 1/8) '(-2/8 1/8 e4 -5/8 1/8) '(-1/8 3/8 c4 1/8 1/8))) Now with your values: (setf row '(c4 cs4 d4 ds4 e4 f4 fs4 g4 gs4 a4 as4 b4)) (setf l-v1 '(1/8 -1/8 2/8 -1/8 5/8) l-v2 '(1/8 1/8 -1/8 2/8 1/8) l-va '(-2/8 1/8 -5/8 1/8) l-vc '(-1/8 3/8 1/8 1/8) ) (setf length (list l-v1 l-v2 l-va l-vc)) (setf pitch (distribute-seq row length)) (setf seq (make-omn :length length :pitch pitch)) (ps 'gm :vn1 (list (1~ seq)) :vn2 (list (2~ seq)) :va (list (3~ seq)) :vc (list (4~ seq)))
