Can I assign integer to attribute, for e.x integer to attribute?

Example please.
No. Integer (number) can't be variable.

I want to define pizz=0, arco-ord =1, arco-tasto=2, arco-ponte=3, then to apply to a string of pitch classes (0-11) mod 4, this will give me another string (0-3) and I want this string to be transformed to a string of attributes according to my definition.

you want to map some integers (in your case pc..) to attributes? like that?

 

(position-filter  '(0 1 2 3 4 5)  '(pizz arco ponte molto-ponte stacc stacc+pizz ten+arco ten+molto-ponte))
=> (pizz arco ponte molto-ponte stacc stacc+pizz)


(position-filter  (pcs '6-Z10) '(pizz arco ponte molto-ponte stacc stacc+pizz ten+arco ten+molto-ponte))
=> (pizz arco molto-ponte stacc stacc+pizz ten+molto-ponte)

or in pure CCL

(loop 
  for i in '(0 1 2 3 4 5)
  with attr-list = '(pizz arco ponte molto-ponte stacc stacc+pizz ten+arco ten+molto-ponte)
  collect (nth i  attr-list))
=> (pizz arco ponte molto-ponte stacc stacc+pizz)

 

Check the mapping functions.

Something like that :

(substitute-map '(pizz arco+ord arco+tasto arco+ponte) '(0 1 2 3) '(0 3 2 3 1 3 2 3 3 1 0 0 2 0))
=> (pizz arco+ponte arco+tasto arco+ponte arco+ord
    arco+ponte arco+tasto arco+ponte arco+ponte
    arco+ord pizz pizz arco+tasto pizz)

SB.

Thank you!
