Transpose whole list

[david]

ok, thank you for your clarity, I understood everything!

I try to use the function filter-repeat 1 to avoid repetitions of notes like here,  it doesn't work

 

(loop for i in '(0 5 -2 3 8 1 6 -1 4 9 2 7)
      append (pitch-transpose i 
                     (loop for bar in mat collect 
                             (list (filter-repeat 1 (rnd-order (first (gen-divide 5 bar)) :type :pitch) (second (gen-divide 5 bar)))))))

This style of code is hard to read and considered poor practice. It's advisable to use variables for individual expressions, especially when you're just starting out. Before stating that something isn't working, it's a good idea to study the function carefully and run some tests or experiments.

 

Good forum etiquette suggests starting a new post if the previous issue has been resolved. Otherwise, we risk having a single, elongated conversation that strays from the original topic indicated by the post title.

You are right, I will open a new message!

 

but I was just saying I had an error message...that is all!
