Hi
I wonder how can i do to create values of an array mapped in different order on another one.
for example an array of 4 values 1/42 ,2/36, 3/48 , 4/29 mapped in 1-3, 2-4 , 3-1, 4-2 give 1/48, 2/29 , 3/42, 4/36.
it's looks simple but i don't see any efficient solution...

not sure to understand..how do you enter the value 1/42 in an array..?

I input the 42 value on the index 1 of my array

I want to map the indexes not the values

ok, i suppose a script will be better, but here a try, certainly not perfect but can be an inspiration source..?

very intersting but not in realtime unfortunatly. this is my version
unfortunatly this one is limited by the polyphonic aspect of it.
maybe it could inspire someone
