Hey im trying to easily define recursive music structures and im a little stuck.
given a beat number that increments every note, a root (say 50), and a pattern (say [0 -2 -4 -2]), and a list of layers (say (4,16))

i wanna iterate over the pattern every 1 so it completes the cycle every 4:  0, -2, -4, -2, 0 etc...
and also every four so it completes the cycle every 16: 0 0 0 0 -2 -2 -2 -2 etc..

so to isolate the question I lets focus on 16: what mathmatically would represent getting 0 0 0 0 1 1 1 1 2 2 2 2 (the indexes) at certain beats.

my best guess was  floor((beat modulo 16)/4) but dosnt work obviously
